Final Answer-Explanation:
The external structure of the leaf is adapted to photosynthesis in a number of ways. The leaf is typically broad and flat, which maximizes its surface area for absorbing sunlight. The leaf is also typically thin, which allows for the diffusion of gases, such as carbon dioxide and oxygen, into and out of the leaf. The leaf is also covered in a waxy cuticle, which helps to prevent water loss.
The internal structure of the leaf is also adapted to photosynthesis. The leaf contains a number of chloroplasts, which are the organelles in which photosynthesis takes place. Chloroplasts contain chlorophyll, which is a green pigment that absorbs sunlight. The light energy absorbed by chlorophyll is used to split water molecules into hydrogen and oxygen. The hydrogen is then used to create glucose, a sugar that is used by the plant for energy. The oxygen is released into the atmosphere.
The leaf also contains a number of veins, which transport water and nutrients to the chloroplasts. The veins also transport the glucose that is produced by photosynthesis to other parts of the plant.
The leaf is a remarkable organ that is essential for the survival of plants. The external and internal structure of the leaf are perfectly adapted to the process of photosynthesis.
