B K.C. Mehta:- He Investigated the effects of temperature on rust fungi growth. He performed his research in the field of fungus-induced plant rusting, which changes the colour of plant leaves from green to brown, red or orange. - P. Maheswari:- He Discovered the production of haploid anther culture. Haploid cells are excellent tools to study gene function as they contain a single copy of the genome and are thus unable to mask the effect of mutations. - Cohen and Boyer:- They Discovered recombinant DNA technology. A recombinant DNA molecules are produced by joining together two or more DNA segments usually originating from different organisms. - Singer and Nicolson:- Proposed the fluid mosaic model of the cell membrane. According to this model membranes are made up of lipids, proteins and carbohydrates. The main lipid membrane components are phospholipids.

Choose the correct group of organisms based on their cell wall materials respectivelyCellulose, Peptidoglycan, Algin, Mycolic acid and Pseudomurein.
B Ulothrix is an example of green algae having barrel shaped or cylindrical cells. The cell wall of green algae is composed of propectin and cellulose. Bacillus is a type of bacterial cell or bacteria. Bacterial cell is made up of peptidoglycan, often known as mureine. Laminaria belongs to the phaeophyceae. The cell wall of Laminaria is made up of cellulose and algin. The cell wall of Corynebacterium and Mycobacterium specieses are made up of mycolic acids. Pseudomurein is present in the cell wall of methanogenic archaebacteria.

Energy is used in which of the following ?
1 Active absorption
2 Passive absorption
3 Diffusion
4 None of the above
Explanation:
A Active absorption is the absorption of water by roots using adenosine triphosphate produced by root respiration ; It is called active absorption because the roots cells actively participate in the process. Diffusion- The movement of molecule from a region of higher concentration to a region of lower concentration.

Which of the following lacks cell wall?
1 Gametes
2 Amoeba
3 Mycoplasma
4 All of these
Explanation:
D Cell wall is the outer covering of all plants, fungi and some bacterial cell, it surrounds the plasma membrane. Cell wall is not found in animal cell. Like all prokaryotes mycoplasma lacks the cell wall, mycoplasma is a genus of bacteria. Amoeba lacks a cell wall like other protozoans. Cell wall absent in gametes also.
