Question:

Underground modification of stem occurs for following special functions, except

Options:

1. Storage of food
2. Vegetative propagation
3. Assimilation
4. Perennation

Solution:

Underground modification of stems, such as rhizomes, bulbs, corms, and tubers, serve various functions including storage of food, vegetative propagation, and perennation (survival during adverse conditions). However, assimilation, which is the process by which plants produce organic compounds using sunlight, carbon dioxide, and water, primarily occurs in the leaves and other green aerial parts of the plant through photosynthesis. Underground stems are not typically involved in the process of assimilation, so option 3 is incorrect. Options 1, 2, and 4 are all valid functions of underground stem modifications.
