What is the primary function of leaves in plants?

The primary function of leaves in plants is to carry out photosynthesis and gas exchange. Leaves are equipped with chlorophyll, which is a pigment that captures sunlight and uses it to convert carbon dioxide from the air and water from the soil into glucose and oxygen through the process of photosynthesis. This essential process not only provides energy for the plant but also releases oxygen into the atmosphere, which is vital for many living organisms.

Additionally, leaves have structures called stomata that allow for the exchange of gases, facilitating the intake of carbon dioxide and the release of oxygen during photosynthesis. This dual role in energy production and gas exchange highlights the critical importance of leaves in the overall health and functioning of plants.

In contrast, while leaves might play a minimal role in water absorption, that function primarily belongs to roots. Nutrient storage is often handled by different plant structures such as stems or roots, and although leaves can sometimes store sugars temporarily, they are not primarily designed for nutrient storage. Supporting the plant structure is mainly attributed to stems and roots, which provide stability and support for the plant to grow upright.
