Question

Read the given statements and select the correct option.

(i) One maize root cell can give rise to more than 17,500 cells.
(ii) A cell in watermelon can increase in size upto 3,50,000 times.
(iii) The growth of pollen tube is measured in terms of length.
(iv) The growth of the leaf is measured in term of surface area.

• A. Statements (i) and (ii) are correct.
• B. Statements (iii) and (iv) are correct.
• C. Statements (i) and (iii) are correct.
• D. Statements (i), (ii), (iii) and (iv) are correct.

Answer 1

The correct option is D Statements (i), (ii), (iii) and (iv) are correct.

The root cells may give rise to more than 17,500 cells, the cells of the root undergo mitotic division in an arithmatic manner, where some of the dividing cells undergo differentiation while others continue to divide.

A water melon pulp contains about 90% of water, so the enormous increase in size of the cell is due to endosmosis.

The growth of the pollen tube is measures in $\mu$ meters

A leaf visually is a two dimensional structure hence it is measured in terms of surface area.

So, the correct answer is 'Statements (i), (ii), (iii) and (iv) are correct.'
