The megaspore mother cell thus, undergo meiotic division forming four megaspores. The red thalli of most of the red algae are multicellular. Ans: Pteridophytes have seedless vascular plants. Figure 1.18: Parts of two representative animal cells as seen with a TEM. (ii) Vascular tissues are not present. Life Cycle They improve mineral content of soils. (i) Ferns are used by florists for decoration purposes. Bryophytes live on land but require water to complete their life cycle. It consists of 8 haploid nuclei embedded in the cytoplasm of which 3 cells lie at the micropylar end and 3 antipodal lies at the chalazal end. Ans: The differences between gymnosperms and pteridophytes are listed below: 18. Between 4. Technology and Livelihood Education (TLE) is one nomenclature in the implementation of the K to 12 Basic Education Program (BEP). 0000003462 00000 n (PDF) Bioprocess Engineering-Basic Concepts by Shuler and Bryophytes: Bryophytes can live on soil but are dependent on water for sexual reproduction. Which groups of plants are called vascular cryptogam? in RNA, the adenosine linksis described. The seeds of gymnosperms are not covered that is they are naked but in Angiosperms, the seeds remain closed inside the fruit hence both of these are classified separately. Accordingly, they are termed as herbs, shrubs and trees. Fertilisation and Development of a Seed The key difference between glucose and starch is that glucose is the simplest form of carbohydrate that can easily be absorbed by the digestive system, while starch is a complex form of carbohydrate that cannot be easily absorbed by the digestive system.. Carbohydrates are a type of macronutrient normally found in certain types of food and drinks. Zostera is a marine angiosperm. Hence, it is essential for amphibians to breed. The phylogenetic system of classification are mainly the rearrangement of taxonomic characters in addition to the phylogenetic information. The spores germinate to give rise to inconspicuous, small but multicellular free-living, mostly photosynthetic thalloid gametophytes called prothallus. Both phases are multicellular. 'c{ The terms stacking gel and separating gel are used in explaining the SDS-PAGE technique.SDS-PAGE or sodium dodecyl sulfate-polyacrylamide gel electrophoresis is a laboratory technique that is used to separate protein molecules based on their molecular weights.The theory behind the technique is that Example: Riccia, Marchantia, Funaria. These spores germinate to form free-living gametophytes, e.g., Riccia, Marchantia, Pellia, Porella, etc. So, click on the PDF Download option to access the file and save it for offline study. Compare the Difference Between Similar Terms. (b) Size They range from simple branched, filamentous forms (Ectocarpus) to profusely branched forms as represented by kelps. Disadvantages One sperm fuses with an egg and produces a diploid zygote. (i) Thallophytic: The plant body is thallus i.e. Morphological and ultrastructural changes in bacterial cells as an indicator of antibacterial mechanism of action. Cellular and molecular life sciences: CMLS., U.S. National Library of Medicine, Dec. 2016. (ii) Species of Sphagnum (a moss), provides peat that Your email address will not be published. Choose all similarities between starch and cellulose? (c) Diplohaplontic Life Cycle: It has well developed multicellular haploid and diploid phases. (ii) In both, the male sex organ consists of a jacket of sterile cells enclosing a spermatogenous tissue. Ans: Heterospory refers to the production of two kinds of spores in pteridophytes eg. This is the key difference between Mode of Action and Mechanism of Action. They have similarities and differences both in structure and chemistry. They are used in scrubbing and polishing. 3. in RNA, the adenosine linksis described. The pH of this gel is maintained as pH=8.8, which is a higher pH level than that of the stacking gel. Meiosis in the zygote results in formation of haploid spores. 4.1 Biological Molecules Some mosses grow in desert bogs and streams. 0000106076 00000 n Ans: The structure of the Prothallus of fern has been defined below: (ii) Sex organs antheridia and archegonia are present on the lower surface of the prothallus. The cells are liver cells from a rat (9600). Animals store extra glucose in the form of glycogen, whereas plants store it in the form of starch. Key Difference Stacking Gel vs Separating Gel. J IP (@@QR))u4 BB@uP6BZPbq &00.@l 9L@0b8) 8Gt,>zsLpj5UU>#z']M1l``ateH``Hd'@ @R.:@ :e Through the medium of water, antherozoids reach the archegonia and fertilise the egg. Rhizoids (vi) The sex organs which are Archegonia and antheridia are flask and globose shaped respectively. 1. starch 2. fructose 3. glycogen 4. glucose. Different plant groups and individual have different features in their life cycle Habitat 1. (v) Maidenhair fern is a source of the expectorant. - amylopectin - glycogen. Its pH is acidic than that of resolving gel by 2 pH units. Spore is the beginning of gametophytic generation. Too much starch in the diet has been linked to tooth decay, obesity, and diabetes. Both actions are important in drug designing and metabolism. When the flagella are lost and a cyst wall is formed around them, the zygospore germinates by meiosis to form four haploid meiospores. Pollen grains after dispersal from the anthers are carried by various ways such as wind, water or by various other agencies to the stigma of the pistil. Some cells of the sporophyte undergo reduction division (meiosis) to produce haploid spores (which germinate to produce gametophyte). Dependent Sporopbvrc The sporophyte is not free-living but attached to the photosynthetic gametophyte deriving nourishment from it. Out of which one is enclosed within the megasporangium (nucellus) and develops into a multicellular female gametophyte, bearing two or more archegonia of female sex organs. Antheridium is sessile and surrounded by a single layered jacket. 0000108769 00000 n The cytoplasm contains membrane bound chloroplast, mitochondria, ER, Golgi bodies and other cell organelles. The pH of the stacking gel is 6.8. The seeds are exposed to the surface of the sporophyll. The sporangia produce spores by meiosis in spore mother cells. It contains an antheridium. Fertilisation The leaves may be simple or compound. The megaspores and microspores germinate and give rise to female and male gametophytes respectively. (ii) The diploid saprophyte is represented by a dominant independent photosynthetic vascular plant body. The seeds of gymnosperms are not covered that is they are naked but in Angiosperms, the seeds remain closed inside the fruit hence both of these are classified separately. Between Starch is the stored form of sugars in plants and is made up of amylose and amylopectin (both polymers of glucose). Xylem consists of tracheids and phloem is made up of sieve cells and albuminous cells. The life cycle of moss represents two distinct generations: gametophytic and sporophytic. What is the botanical name for the sea palm? Animals store extra glucose in the form of glycogen, whereas plants store it in the form of starch. (iii) Palmella Stage: If the conditions are unfavourable, daughter cells are divided into numerous cells. Polysaccharides may be very large molecules. When a substance enters a living cell, it brings about physical, chemical, structural and functional changes by interacting with the hosts metabolism and biochemical pathways. Amylopectin is also considered insoluble, meaning that it does not dissolve in water. The chain may be branched or unbranched, and it may contain different types of monosaccharides. the Difference Between Glucose and Starch (iii) Development of strong woody material anchor and support above-ground structures. Monocots and dicots differ from each other as: Gymnosperms like conifers have needle-shaped Ieaves to reduce surface area, thick cuticle and sunken stomata to reduce water loss therefore, the leaves in gymnosperms are adapted to withstand xerophytes conditions. * Sexual reproduction may be isogamous, anisogamous or oogamous. The generative nucleus divides pollen tubes producing two male gametes. : The plant body is thallus i.e. (iii) Most of the plants are gametophytes that develop from haploid spores. The key difference between amylose and amylopectin is that amylose is a straight-chain polymer while amylopectin is a polymer with a branched-chain. Spores The food is stored as floridean starch which is very similar to amylopectin and glycogen in structure. These organs possess well differentiated vascular tissues. Their walls become gelatinous and cells remain together. Ans: There are three types of life cycle found in green algae: (a) Haplontic Life Cycle: The dominant phase is haploid. Male gamete reach the female gamete through a pollen tube. (i) Seeds of Pinus gerardiana (chilgoza) are used a food after roasting. depending on the type of pigment possessed and the type of stored food. Studying the important questions and answers will help you to understand the important topics from this chapter. In this way, each character is given equal importance and at the same time hundreds of characters can be considered. 11. 0000002995 00000 n Some members like Azolla, Salvinia, Marsilea species. structural polysaccharides - cellulose-chitin. The plant body is distinguished into three parts- i) underground stem rhizome ii) it bears roots and iii) it sends aerial shoots with leaves. Please only fill blanks with the names of the groups without specifying which atom they are attached to. * The brown algae that are used as food are Laminaria, Nerocystis, Macrocystis, Alaria, etc. It alternates with multicellular saprophytic/autotrophic, Ans: Selaginella and Salvinia are organisms that exhibit heterospory and seed habits. The key difference between stacking gel and separating gel is thatthe pH of the stacking gel is 6.8 whereas the pH of the separating gel is 8.8. Stamens and pistils are the two reproductive parts of a flower. Mode of action of a biomolecule refers to the mode in which the action is brought about and is characterized by the changes that take place in a cell. Because of the structural and chemical similarities between amylopectin and glycogen, it is used to refer to a component of the animal's glycogen. Roots of some gymnosperms have a fungal or algal association. The separating gel contains a high amount of polyacrylamide (10%). This stage is the palmella stage. The mosses have an elaborate mechanism of spore dispersal, e.g., Funaria, Polytrichum and Sphagnum. lb+V ("Y3Hs^t"hjuz{`mu De{+3D6rDbziBMeC Sbsp{R Z"IZ!2M?rs[24;{+hLT Angiosperms Ans: Laminaria is used for fodder for poultry birds. (ii) They also provide valuable timber and medicines. Similarities Between Mode of Action and Mechanism of Action The haploid phase is either microscopic or represented by gametes only (e.g., Fucus). Stacking gel and separating gel are two types of polyacrylamide gels used to get better separation of protein molecules in a given sample. Algae and Bryophytes are different from each other. Point out the main differences between them? Seeds Food Material Haploid gametophytes produce haploid gametes. Phycobilins are water soluble and are of two types, i.e., red-coloured phycoerythrin and blue-coloured phycocyanin. Numerical Taxonomy Haploid gametophytes produce haploid gametes.

Figure 02: Example of EMA401 Mechanism of Action: Inhibition of TRPV1 Phosphorylation. How is it different from protonema? In pteridophytes, the main plant is a sporophyte and It is differentiated into true roots, stem, and leaves. Penicillin acylates the active site of Bacillus Stear thermophilous D-Alanine carboxypeptidase. The Journal of biological chemistry., U.S. National Library of Medicine, 10 May 1980. Embryo (a) Habitat These are mostly marine forms, only some are freshwater. (b) Heterogamy In this process, fusion occurs between morphologically as well as physiologically different gametes. Write two important characteristics of gymnosperms? It is partially embedded. Ans: The leafy stage develops from the secondary protonema as a lateral bud in mosses. Example- Equisetum, (iv) Class 4: Pteropsida. Bryophytes are thallus-like and prostate attached to the substratum by rhizoids and they also possess root-like, leaf-like, and stem-like structures. Flowers Cellulose Structure It alternates with the short lived multicellular sporophyte totally, partially or dependent on the gametophyte for its anchorage and nutrition. Name the organisms which exhibit heterospory and seed habits. Amylose [(C6H10O5)n Ans: The two important characteristics of gymnosperms are: (i) It is a group of vascular plants which possess naked seeds attached to the surface of megasporophyll. Meiosis takes place at the time of its germination. Example- Adiantum and Pteridium. maltase catalyses reaction between maltose and water, where maltose is split to produce two glucose molecules Lock and Key Model: The active site has a specific geometric shape such that only one substrate can bond to that site, making the enzyme specific to that substrate Roots of Adiantum can cure throat infections. 5. 20. All rights reserved. Please only fill blanks with the names of the groups without specifying which atom they are attached to. Amylopectin is also considered insoluble, meaning that it does not dissolve in water. Identify the two major classes of nucleic acids. Their leaves are net-veined, the vascular bundles are arranged in a circle or ring within the stem. 0000142053 00000 n Overview and Key Difference (i) Life Cycle Isomorphic alternation of generation is found in some brown algae, e.g, Ectocarpus, Dictyota.
