Question

How many generations are required by a cell of meristem to produce 128 cells

Answer 1

A single mitotic division of oNe cell produces twO cells. 2nd division of this two cells produces 4 cells and so on. 2^n = Number Of cells after n divisions. Thus 7 generations of mitosis yields 128 cells from a single cell.

Answer 2

In 7th mitotic generation it produces totally 128 cells from single cell.

EXPLANATION:

Meristem is tissue in the plant containing the undifferentiated cells. These cells give rise to organ of the plant and are responsible for growth.  

The numbers of generations required by a cell of meristem to produce 128 cells are as follows

• The single mitotic division produces two cells.
• The second division produces four cells and hence $\bold{2^{n}}$ cell in every generation.
• In 7th mitotic generation it produces totally 128 cells from single cell.
