Main function of leaf isa)Manufacture of foodb)Exchange of gasesc)Both 1 and 2d)None of the aboveCorrect answer is option 'C'. Can you explain this answer?

Question

Answer

C option is correct because as we know that plant make their own food in the presence of light as well as exchange of gases also takes place.

Answer

Its main functions are photosynthesis and gas exchange. A leaf is often flat, so it absorbs the most light, and thin, so that the sunlight can get to the chloroplasts in the cells. Most leaves have stomata, which open and close. They regulate carbon dioxide, oxygen, and water vapour exchange with the atmosphere.

Answer

Leaf is an important organ of a plant that plays a vital role in the process of photosynthesis. It is responsible for the production of food and exchange of gases.

The main function of a leaf is to manufacture food through the process of photosynthesis. During photosynthesis, the leaf uses sunlight, water, and carbon dioxide to produce glucose and oxygen. This glucose serves as the main source of energy for the plant, while oxygen is released into the atmosphere as a byproduct.

The leaf is equipped with specialized structures called chloroplasts, which contain a pigment called chlorophyll. Chlorophyll captures sunlight and converts it into chemical energy, which is used to drive the process of photosynthesis. The leaf also contains numerous tiny openings called stomata, which allow for the exchange of gases.

The exchange of gases is another important function of the leaf. Through the stomata, the leaf takes in carbon dioxide from the atmosphere, which is essential for photosynthesis. At the same time, oxygen produced during photosynthesis is released into the atmosphere through the stomata. This exchange of gases ensures a constant supply of carbon dioxide for photosynthesis and the removal of excess oxygen.

In summary, the main function of a leaf is to both manufacture food through photosynthesis and exchange gases with the atmosphere. Through photosynthesis, the leaf produces glucose, the plant's source of energy, and releases oxygen. The leaf also takes in carbon dioxide and releases excess oxygen through the stomata, ensuring a continuous supply of carbon dioxide for photosynthesis.

Answer

As leaf contains chlorophyll in it that helps in the manufacturing of food and also it contains stomata that helps in gaseous exchange.

Answer

C option is correct because (I)leaves have chlorophyll help in making food(I)it has pores called stomata on it which help in exchange of gases

Answer

Gases exchange and preparation of food take place in leaves
