Select the incorrect statement.
Options
- AGrowth, at a cellular level, is principally a consequence of increase in the amount of protoplasm.
- BIn maize, the growth in root apical meristem growth as an increase in the size of the cell.
- CThe growth of a pollen tube is measured in terms of its length.
- DAn increase in surface area denotes the growth in a dorsiventral leaf.
Correct answer
B. In maize, the growth in root apical meristem growth as an increase in the size of the cell.
Step-by-step solution
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.
