Select the incorrect statement. (A) Growth, at a cellular level, is principally a consequence of increase in the amount of protoplasm. (B) In maize, the growth in root apical meristem growth as an increase in the size of the cell. (C) The growth of a pollen tube is measured in terms of its length. (D) An increase in surface area denotes the growth in a dorsiventral leaf.

Tardigrade Admin · Accepted Answer

In one single maize, root apical meristem can give rise to more than 17,500 new cells per hour, whereas cells in a watermelon may increase in size by up to 3,50,000 times. In the former, growth is expressed as increase in cell number; the latter expresses growth as increase in size of the cell. While the growth of a pollen tube is measured in terms of its length, an increase in surface area denotes the growth in a dorsiventral leaf.
