Question

A leaf is a food factory. Explain.

Answer in Brief

Solution

The leaves of green plants are specially developed for the purpose of synthesizing food. The leaf anatomy is best suited for collecting the raw materials. The leaf absorbs CO2 from the atmosphere through its stomatal openings. It gets water from the stem. The chloroplasts are the actual sites of photosynthetic reactions-light and dark reactions which result in the formation of glucose. Hence, the ability to collect raw materials and to carry on chemical reactions to synthesize food, it is called as the food factory of the plant.
