Growth, at a cellular level, is primarily associated with an increase in the amount of protoplasm. Many parameters are involved in measuring protoplasm growth, including the differences in length, area, volume, and cell number, the weight of the fresh tissue sample and the weight of the dry tissue samples measured during the growth period. As a result, no single parameter is good enough to demonstrate the growth throughout the life of a flowering plant.

‘Both a short-day plant and a long-day plant can flower simultaneously in a given place’. Explain
‘Both growth and differentiation in higher plants are open’. Comment.
