18958.	Question : How does cytokinesis in plant cells differ from that in animals cells ?
Answer» Solution :Cytokinesis in plant CELLS occurs by a process different from that seen in animal cells. In plant cells, a CELL plate is laid down which is usually initiated at the centre and extends TOWARDS the periphery. After the cell plate is laid down, PRIMARY walls are formed on either side of the cell plate. Whereas in animal cells, a cleavage furrow appears at the beginning of TELOPHASE, which becomes progressively deeper as the spindle breaks down. Eventually the ingrowing constrictions join and separate two daughter cells.

18993.	Question : Cyanobacteria plays a major role in our ecology. Discuss.
Answer» Solution :1. Cyanobacteria, also known as 'Blue GREEN algae' help in CARBON fixation in a major way on the ocean surface. 2. They are helpful in nitrogen fixation in paddy FIELDS leading to a BETTER harvest. 3. About 80% of photosynthesis on ocean surface is done by cyanobacteria. So, it can be said that they play a major role in our ecology.

Discussion

18995.	Question : Cyanobacteria are classified under
Answer» Protista Plantae Monera Algae Solution :KINGDOM Monera is such a group in which all forms of bacteria are included.

In other OPTIONS Protista, Algae and plant Eukariyot and UNICELLULAR and multicellular organisms are included.

Discussion

18996.	Question : Cyanobacteria and some otherphotosynthetic bacteria don't have chloroplasts. How do they conduct photosynthesis ?
Answer» Solution :CYANOBACTERIA and photo synthetic bacteria are PROKARYOTIC. They don.t contain MEMBRANOUS organisms. But they possess membranous STRUTURE of photosynthetic pigments. They are of primary level. They can ACCEPT light enrgy and do photosynthesis.

Discussion

18997.	Question : Cyanobacteria and heterotrophic bacteria have beenclubbed together in eubacteria of kingdom Monera as per the Whittaker's 'Five Kingdom Classification' even though the two are vastly different from each other. Is this grouping of the two types of taxa in the same kingdom justified? Is so why?
Answer» Solution :In the two-kingdom classification system, cyanobacteria were included amongst algae, and placed with plants because they share with them many characteristics—the use of chlorophyll a as the MAIN photosynthetic pigment, the use of water as a source of electrons and hydrogen for fixing `CO_2`, the oxidation of water with two photosystems, the release of oxygen as a byproduct of photosynthesis, the presence of cell wall, and blue-green colouration in some cyanobacteria. This taxonomic treatment, primarily based on their plant-like photosynthetic ACTIVITIES, became UNTENABLE around 1960 when fundamental differences in CELLULAR organisation of prokaryotes and eukaryotes were fully elucidated. It is now clear that while cyanobacteria and plants have many common features, they are really very different. While plants are eukaryotes, cyanobacteria are prokaryotes like other monerans. Cyanobacteria evolved at least 2.5 billion YEARS ago, which is roughly 1 billion years before the first eukaryotes. While both plants and cyanobacteria have cell walls, the plant cell wall is made up of cellulose, while the bacterial wall of peptidoglycan. A major difference from plants is that many forms of cyanabacteria can fix atmospheric nitrogen. The ability to fix atmospheric nitrogen is dependent on the enzyme nitrogenase, which can only function under anaerobic conditions. While cyanobacteria do generate oxygen as a product of photosynthesis, certain filamentous types produce specialized cells, called heterocysts, that containnitrogenase and are impervious to oxygen.

Discussion

18998.	Question : Cyanobacteria and heterotrophic bacteria have been clubbed together in eubacteria of kingdom-Monera as per the "five kingdom classification" even though the two are vastly different from each other. Is this grouping of the two types of taxa in the same kingdom justified ? If so, why ? Discuss the cellular composition of cyanobacteria and heterotrophic bacteria that make them introduced in eubacteria.
Answer» SOLUTION :All the prokaryotes have been kept under the kingdom Monera. Both cynobacteria and HETEROTROPHIC BACTERIA are prokaryotes and hence are being kept under the same kingdom. Mode of nutrition is the major difference between cynobacteria and heterotrophic bacteria. So, this classification is justified.

Discussion

18999.	Question : Cut pieces of beetroot do not leave the colour in cold water but do so in hot water. Explain.
Answer» Solution :The PIECES of beetroot does not BECOME colourless but releases colour in hot water. Because the pigments of beet become SOLUBLE in hot water and POSSESS diffusion. Due to hot temperature particles of pigment get help to RELEASE from cell membrane.

Discussion

19000.	Question : Cut a transverse section of young stem of a plant from yourschool garden and observe it under the microscope. How would you ascertain whether it is a monocot stem or a dicot stem ? Give reasons.
