Question

Consider the following statements:
(a) In leguminous plants, leaf base becomes swollen, called pulvinus.
(b) The fleshy leaves of onion and garlic store food
(c) In Alstonia, leaves show alternate phyllotaxy.
(d) The lamina in Australian acacia become green and synthesize food.
Of the above statements.

• A. (b) and (d) are correct
• B. (a) and (c) are correct
• C. (a) and (b) are correct
• D. (b) and (c) are correct
• E. (a) and (d) are correct

Answer 1

The correct option is C (a) and (b) are correct

The swollen leaf based is called as pulvinus. It is present at the base or apex of the petiole. Pulvinus leaf base is commonly seen in leguminous plants. Bulbs are storage organs with fleshy leaves. They store food and water. Examples include onion and garlic. These are also called as bulbous vegetables. The petiole in Australian acacia become green and synthesize food. The buds are short lived. Phyllotaxy is the arrangement of leaves on the stem. It is of 3 types, namely opposite, alternate and whorled. In Alstonia, leaves show whorled phyllotaxy.

Thus, the correct answer is '(a) and (b) are correct.'
