What are the primary functions of leaves on a plant?

Leaves serve multiple critical functions that are essential for a plant's survival and overall health. The primary functions of leaves include photosynthesis, transpiration, and gas exchange.

Photosynthesis is the process by which leaves capture sunlight and convert it into chemical energy, using carbon dioxide from the air and water from the soil to produce glucose and oxygen. This process not only provides energy for the plant but also releases oxygen into the atmosphere, which is vital for the survival of many organisms.

Transpiration is the process of water vapor loss from the surface of leaves, which helps to regulate temperature within the plant and maintain the flow of nutrients and water from the roots to the leaves. This loss of water is essential in creating a negative pressure that assists in drawing water up through the plant.

Gas exchange occurs through small openings on the underside of leaves called stomata, allowing the entry of carbon dioxide necessary for photosynthesis and the exit of oxygen produced as a byproduct. This exchange is crucial for maintaining the plant's metabolic processes and overall health.

In contrast, the other options do not encompass the key roles of leaves. Water absorption and nutrient storage are primarily functions of roots, while flower production and seed dispersal pertain to reproductive structures in the plant. Support and
