Photosynthesis and Leaf Structure Flashcard

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water, and releasing oxygen as a byproduct.

Front

What are the main parts of a leaf involved in photosynthesis?

Back

The main parts of a leaf involved in photosynthesis are the palisade layer, spongy layer, stomata, and chlorophyll.

Front

What is the function of the palisade layer in a leaf?

Back

The palisade layer is responsible for most of the photosynthesis in a leaf due to its high concentration of chloroplasts.

Front

What is the role of the spongy layer in a leaf?

Back

The spongy layer facilitates gas exchange and contains air spaces that allow carbon dioxide to diffuse to the palisade layer.

Front

What are 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 function of stomata?

Back

Stomata are small openings on the surface of leaves that allow for gas exchange, enabling carbon dioxide to enter and oxygen to exit.

Front

What is xylem?

Back

Xylem is a type of vascular tissue in plants responsible for the transport of water and minerals from the roots to the rest of the plant.

Front

What is phloem?

Back

Phloem is a type of vascular tissue that transports sugars and other metabolic products downward from the leaves.

Front

What is the cuticle in a leaf?

Back

The cuticle is a waxy layer on the surface of leaves that helps reduce water loss and protect against environmental damage.

Front

What is chlorophyll?

Back

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