Internal leaf

Front

What is the main function of the leaf?

Back

The main function of the leaf is to make food through the process of photosynthesis.

Front

What are guard cells?

Back

Guard cells are specialized cells that control the opening and closing of stomata, regulating gas exchange in the leaf.

Front

What is the role of stomata in leaves?

Back

Stomata are small openings on the leaf surface that allow gases like carbon dioxide and oxygen to enter and exit the leaf.

Front

Where are most chloroplasts found in a leaf?

Back

Most chloroplasts are found in the palisade mesophyll layer, which is located just beneath the upper epidermis.

Front

What is the cuticle in a leaf?

Back

The cuticle is a waxy layer that covers the leaf surface, helping to reduce water loss.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

What is the upper epidermis?

Back

The upper epidermis is the outer layer of cells on the top side of the leaf, providing protection and helping to reduce water loss.

Front

What is the palisade mesophyll layer?

Back

The palisade mesophyll layer is a layer of tightly packed cells in the leaf that contains many chloroplasts for photosynthesis.

Front

What is the lower epidermis?

Back

The lower epidermis is the outer layer of cells on the underside of the leaf, which also contains stomata.

Front

What gases are exchanged through the stomata?

Back

The gases exchanged through the stomata are carbon dioxide (CO2) and oxygen (O2).
