The branch of Biology dealing with structure, function and reproduction of cell is:
1 Cytology
2 Anatomy
3 Histology
4 Cell biology
Explanation:
D The study of structure and function of the cell called cell biology including. Physiology, biochemistry and genetics. Cytology is the study of structure of cell where as histology is the study of tissue and cells.

Comparing small and large cells, which statement is correct?
1 Small cells have a small surface area per volume ratio
2 Exchange rate of nutrients is fast with large cells
3 Small cells have a large surface area per volume ratio
4 Exchange rate of nutrients is slow with small cells
Explanation:
C To maintain surface area - to - volume ratio in a balanced state, some cells are provided with microvilli, which increases the absorptive area. In small cells the random, tiny motions of molecules can easily distribute material. Small cell have a large surface area per volume ratio.

Which of the following is not a function of water in cell?
1 It provides energy for chemical reaction
2 It act as a solvent
3 It provides a medium for chemical reaction
4 It release hydrogen ions on ionization
Explanation:
A Providing energy for chemical reaction is not a function of water in cell. Water use as universal solvent and act as a maintain a cell inside.

Auxetic growth is increase in
1 cell number only
2 cell volume only
3 fatty tissue
4 intercellular material
Explanation:
A Auxetic growth:- growth in certain organism happens as a result of an increase in cell size. There are exactly the same amount of cells. Cell growth result in an increase in body size. For example- Nematodes, rotifers and tunicates.

Which of the following sentences is correct?
1 Cells of all living organisms have a nucleus
2 Both animal and plant cells have a well defined cell wall.
3 In prokaryotes there are no membrane bound cell organelles.
4 Cells are formed de novo from abiotic materials.
Explanation:
C Prokaryotic cells are simple cells that don't have a nucleus or membrane - bound organelles. They do have DNA and Ribosome. The absence of intracellular compartmentalization indicates the primitive nature of prokaryotic cells. Eg. Bacteria blue green algae, archaea, mycoplasma etc.
