Front

What are stomata?

Back

Stomata are small openings on the surface of leaves that allow gases, such as carbon dioxide and oxygen, to enter and exit the leaf.

Front

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts, which are organelles found in plant cells.

Front

What is the function of chloroplasts?

Back

Chloroplasts are responsible for converting light energy into chemical energy through the process of photosynthesis.

Front

What is the palisade mesophyll layer?

Back

The palisade mesophyll layer is a layer of elongated cells located just beneath the upper epidermis of the leaf, where most chloroplasts are found.

Front

What are palisade cells?

Back

Palisade cells are tightly packed, elongated cells in the palisade mesophyll layer that contain chloroplasts and are primarily responsible for photosynthesis.

Front

What is the role of guard cells?

Back

Guard cells are specialized cells that surround stomata and control their opening and closing, regulating gas exchange and water loss.

Front

What is the upper epidermis of a leaf?

Back

The upper epidermis is the outer layer of cells on the top side of the leaf that provides protection and helps reduce water loss.

Front

What is the lower epidermis of a leaf?

Back

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

Front

What is the spongy mesophyll layer?

Back

The spongy mesophyll layer is located beneath the palisade mesophyll and contains loosely arranged cells with air spaces that facilitate gas exchange.

Front

What is chlorophyll?

Back

Chlorophyll is a green pigment found in chloroplasts that absorbs light energy for photosynthesis.
