Leaf structure/function and photosynthesis

Front

What is the upper epidermis of a leaf?

Back

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

Front

What role do xylem cells play in photosynthesis?

Back

Xylem cells transport water from the roots to the leaves, which is essential for the process of photosynthesis.

Front

What are palisade cells?

Back

Palisade cells are elongated cells located beneath the upper epidermis of a leaf, where most photosynthesis occurs due to their high chlorophyll content.

Front

What is the function of stomata in leaves?

Back

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

Front

How do guard cells regulate gas exchange?

Back

Guard cells surround each stoma and control its opening and closing, thus regulating the exchange of gases and water vapor.

Front

What is the spongy layer in a leaf?

Back

The spongy layer is a layer of loosely packed cells in the leaf that allows for gas exchange and contains air spaces for the diffusion of gases.

Front

What is the cuticle of a leaf?

Back

The cuticle is a waxy layer on the surface of the leaf that helps prevent water loss.

Front

What is the primary function of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in plants that absorbs light energy, primarily from the sun, to drive the process of photosynthesis.

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 are the products of photosynthesis?

Back

The products of photosynthesis are glucose (a sugar) and oxygen.
