Question

In colocasia, _______ is modified to store the food.
A. Stem
B. Root
C. Leaves
D. Flowers

Answer 1

Hint: We have to know that in the genus Araceae, Colocasia is a genus of flowering plants indigenous to southeastern Asia and the Indian subcontinent. In other tropical and subtropical areas, several plants are extensively cultivated and naturalised. It is an outstanding source of resistant starch and fiber, which account for many of its health benefits.

Complete answer:
In order to perform some functions, the vegetative parts of the plants have been changed. The colocasia plant stem has been altered into a corm. Corm is used in the form of carbohydrates that can be used as the food supply for the preparation of the food.
It is possible to grow the plant on the ground or in large containers. In subtropical and tropical countries, they are grown outdoors year-round. They are planted out for the summer in temperate regions and dug up and stored over winter, dry and with ventilation to avoid fungal infection. In more or less any temperature region, as long as the summer is warm, they can be fully developed. At temperatures between 20 to 30°C, growth is best. If temperatures fall below 10°C for more than a few days, the plants can be affected.
So, the correct answer is “Option A”.

Note:
Popular preparations include curry cooking, frying, and boiling. The roots and leaves of Colocasia are abundant in carbohydrates, dietary minerals, and protein. Iron, copper, magnesium, potassium, and zinc are also micronutrients. Phytochemicals such as anthraquinones, apigenin, catechins and derivatives of cinnamic acid, vitexin, and isovitexin are found in Colocasia leaves.
