What is the job of the leafs?

The main function of a leaf is to produce food for the plant by photosynthesis. Chlorophyll, the substance that gives plants their characteristic green colour, absorbs light energy. The internal structure of the leaf is protected by the leaf epidermis, which is continuous with the stem epidermis.

What are the two main functions of the leaf?

The two main functions performed by the leaf are photosynthesis and transpiration. Photosynthesis is the process by which green plants make their food from carbon dioxide and water in the presence of sunlight.

How does a leaf make food?

Light work

Their roots take up water and minerals from the ground and their leaves absorb a gas called carbon dioxide (CO2) from the air. They convert these ingredients into food by using energy from sunlight. This process is called photosynthesis, which means 'making out of light'.

How do leaves help trees?

Leaves make food for the whole plant, keeping it alive by converting sunlight into energy. If a plant or tree does not have healthy, functioning leaves it will die as it would be unable to feed itself. Photosynthesis is the process that plants use to make food, which requires light, carbon dioxide and water.

Why are leaves important to plants?

Leaves provide food and air to help a plant stay healthy and grow. Through photosynthesis, leaves turn light energy into food. Through pores, or stomata, leaves “breathe” in carbon dioxide and “breathe” out oxygen.

What is a leaf answer?

The term leaf refers to the organ that forms the main lateral appendage on the stem of vascular plants. In general, leaves are thin, flat organs responsible for the photosynthesis of the plant.

What is the role of leaves in photosynthesis for Class 7?

Answer: Leaves are designed and adapted to allow photosynthesis to take place. They are flat and broad to capture as much of the light energy from the sun as possible. They also contain lots of tiny holes called stomata which allow for the absorption of carbon dioxide and the release of oxygen.

How do leaves produce?

Leaves make food via the process of photosynthesis. Photosynthesis is the act of making food from water, carbon dioxide, energy from the sun and nutrients.

What makes plants green?

Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green. Plants that use photosynthesis to make their own food are called autotrophs.

What eats a leaf?

Rabbits, Voles, Woodchucks, Deer, Chipmunks, Squirrels. All eat leaves or fruits of plants in vegetable gardens.

How do leaves help the environment?

Leaves break down quickly and will make great fertilizer for your garden or yard in the spring. Use them as mulch around plants. Leaves provide some protection to plants in cold weather, and as they break down they add nutrients to the soil.

What happens in the leaves of a plant?

Photosynthesis– a process that happens in the leaves of plants where sunlight, water, and carbon dioxide (from the air) are converted into food and oxygen. Chlorophyll– a chemical that is in leaves throughout the year and that helps them make food through photosynthesis. It is also what makes leaves green.

Why trees lose their leaves?

The main reason for leaf drop on most trees is that, come winter, it gets pretty cold and dry in our part of the world. Rather than expend energy to protect these fragile organs, trees shed leaves to conserve resources.
