Question

Reproductive leaves are found in
A. Allium
B. Bryophyllum
C. Saccharum
D. Argemone

Answer 1

Hint: A special type of reproduction occurs wherein the leaves are modified to form reproductive leaves. These leaves have the ability to form a whole new individual.

Complete Answer:
This kind of leaves usually forms a tiny plant at the ends or edges of the leaves. They have the capability to form the new organisms when they detach from the parent plant as they fall on ground. Air plants generally have their notches along the leaf margins and have their own roots. These leaves or the plants bearing them thus show asexual mode of reproduction.
Let us analyse the options to find out which plants have reproductive leaves.

Option A: Allium produces capsules which are ball shaped and black colour. They repeduce through asexual mode of reproduction through bubils in the flower head.Therefore, this is the incorrect option.

Option B: Bryophyllum are also called air plants. In these plants, the reproduction occurs through the leaves. The newly formed leaves which are tiny plants detach from the parent plant and grow into a mature plant once it touches the soil.Therefore, this is the correct option.

Option C: Saccharum also called the sugarcane plant reproduces through the pieces of stem called as cuttings. Therefore, this is the incorrect option.

Option D: Argemone reproduction occurs through seeds and produces 30,000 seeds per year.Therefore, this is the incorrect option.

Thus, the correct option is B Bryophyllum.

Note: The leaves of the Bryophyllum have broad possessions notches at the margins. Their buds also called epiphyllous buds have the potential of new plant leaves having shoots and small leaves.
