Question

A flower represents a complex array of functionally specialised structures that differ substantially from vegetative plant body in form and cell types.

Select the statements that is not true with regard to floral meristems.

• A. Floral meristems are larger in size than the vegetative meristems
• B. Increase in size of the floral meristem is due to larger size of the cells, which in turn results from rapid cell expansion only
• C. Increase in size of the floral meristem is largely a result of increased rate of cell division in central cells
• D. A floral morphogenesis is controlled by a network of genes in plants

Answer 1

The correct option is B Increase in size of the floral meristem is due to larger size of the cells, which in turn results from rapid cell expansion only

During the reproductive phase of a shoot apex, the width of floral meristem increases, become less conical and grows. This increase in size is because of the increase in rate of cell division in the central cells.

Thus, the correct answer is (B).
