Answer:
Leave is an important structure of plant body where food production occurs in the process of photosynthesis. In the leaves, small tiny pores called stomata are present on lower side of the leaf. These pores are responsible for the exchange of gases such as carbondioxide and oxygen. These stomata opens and carbondioxide is absorbed from the atmosphere and water from the soil. Both reactants combine in the presence of sunlight producing oxygen and glucose. Oxygen is released through stomata and glucose is stored in different parts of plant.

I think it’s b not sure though
Answer:
The difference between the microfilaments, intermediate filaments, and microtubules are stated below.
Explanation:
- They are made up of two chains made up of monomeric globular proteins called actin. The chains are coiled around each other.
- They have a diameter of about 7 nanometre.
- They help in cellular movement.
- They form strands which are made up of fibrous proteins like keratin, vimentin, desmin.
- They have a diameter which ranges from 8 nanometre to 10 nanometre.
- They have structural function and are required to maintain the cell shape and organelle position.
- They are formed when the globular proteins, alpha-tubulin and beta-tubulin form dimer and undergo polymerisation.
- They have a diameter of about 25 nanometre.
- They form the structural components of flagella, cilia and centrioles. They prevent cell compression.
