Answer 2

Answer:

Option (4) Wheat

Explanation:

• A plant usually goes through 3 phases namely

1. Juvenile or vegetative phase

2. Reproductive or mature phase or recovery phase

3. Old age or senescent phase

• The recovery phase describes the period between two flowering phases. This is otherwise known as the inter-flowering phase or the inter-flowering period.

• During this period, the plant accumulates all the necessary resources essentially required for flowering.

• Polycarpic plants are long-lived plants that can reproduce more than once in their lifecycle before dying. And thus they undergo the recovery phase.

• Since mango, orange, jack fruit comes under polycarpic plants that remain sexually active throughout life and do not die after flowering and fruiting.

• But the wheat plant is a monocarpic plant that is short-lived and dies after flowering and fruiting occur. hence no recovery phases are seen here.

Hence Option (4) is correct.
