* Photosynthesis: This is the primary function of leaves. They contain chlorophyll, a green pigment that captures sunlight. This energy, along with water and carbon dioxide, is used to create sugars (glucose) for the plant's growth and development.
* Transpiration: Leaves release water vapor through tiny pores called stomata. This process helps regulate the plant's internal temperature and draws water up from the roots.
* Gas Exchange: The stomata also allow for the exchange of gases. The plant takes in carbon dioxide for photosynthesis and releases oxygen as a byproduct.
* Nutrient Uptake: Leaves can absorb nutrients from the air, such as nitrogen, through tiny hairs on their surface.
In summary: Leaves are the plant's food factories, helping the bean plant grow, thrive, and produce seeds.
