NEET BIOLOGY

Detailed explanation-1: -Like other multicellular organisms, plants grow through a combination of cell growth and cell division. Cell growth increases cell size, while cell division (mitosis) increases the number of cells. As plant cell s grow, they also become specialized into different cell types through cellular differentiation.

Detailed explanation-2: -The process of mitosis generates new cells that are genetically identical to each other. Mitosis helps organisms grow in size and repair damaged tissue.

Detailed explanation-3: -Body tissues grow by increasing the number of cells that make them up. Cells in many tissues in the body divide and grow very quickly until we become adults. When we are adults many cells mature and become specialised for their particular job in the body.

Detailed explanation-4: -Cell division leads to exponential increase in cell number. More cells mean more synthesis of biomolecules, without disturbing the homeostasis of the organism. This is the reason why cells increase in number and not in their size.

Detailed explanation-5: -Cell proliferation is the process of generating an increased number of cells through cell division. Both cell division and growth are tightly linked to the cell cycle and its regulation.
