Leaf Structure, Pigments, and Light Review

Front

What are guard cells?

Back

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

Front

What is the function of stomata?

Back

Stomata are small openings on the leaf surface that allow for gas exchange, enabling the intake of carbon dioxide and the release of oxygen.

Front

What pigment is responsible for the green color in plants?

Back

Chlorophyll is the pigment that gives plants their green color and plays a crucial role in photosynthesis.

Front

What is the stroma in a chloroplast?

Back

The stroma is the liquid portion of the chloroplast where the light-independent reactions of photosynthesis occur.

Front

What are the openings on the lower leaf epidermis called?

Back

The openings on the lower leaf epidermis are called stomata.

Front

What role do chloroplasts play in plants?

Back

Chloroplasts are organelles in plant cells that conduct photosynthesis, converting light energy into chemical energy.

Front

What is the function of the cuticle in leaves?

Back

The cuticle is a waxy layer that covers the leaf surface, helping to reduce water loss and protect against environmental damage.

Front

What are palisade cells?

Back

Palisade cells are elongated cells located beneath the upper epidermis of leaves, containing chloroplasts for photosynthesis.

Front

What are spongy cells?

Back

Spongy cells are loosely packed cells in the lower part of the leaf that facilitate gas exchange and contain chloroplasts.

Front

What is the role of xylem in leaves?

Back

Xylem is responsible for transporting water and minerals from the roots to the leaves.
