Question

In amorphophallus and Colocasia (Ariods) an extremely enlarged underground vertical stem meant for vegetative reproduction and storage is:
A) Tuber
B) Corm
C) Bulb
D) Rhizome

Answer 1

Vegetative reproduction is a type of asexual reproduction which occurs in plants in which another plant develops from a fragment of the parent plant or a specific regenerative structure. Numerous plants normally reproduce along this way, yet it can likewise be prompted and induced artificially.

Colocasia is a genus of flowering plants in the family Araceae, local to southeastern Asia and the Indian subcontinent. A few species are generally developed and naturalized in other tropical and subtropical regions.

The corm is a short underground stockpiling and storage organ of the plant. It is a swollen stem which stores food to endure winter, summer dry season and warmth. It is additionally called a bulbot rubber. It is covered with scale leaves or tunics. It is found in plants like Amorphophallus, Colocasia, Corcus. A corm comprises at least one internode. Inside, a corm consists of parenchyma cells wealthy in starch.

Therefore, the correct answer for this question is B, i.e. Corm

Note: There are two sorts of proliferation: sexual and asexual. Sexual reproduction is the association of the pollen and egg, drawing from the genes of two parents to make another, third individual. Sexual reproduction includes the floral parts of a plant.
