What is the function of stomata in leaves?

Back

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

Front

What is phloem and what role does it play in plants?

Back

Phloem is a type of vascular tissue in plants responsible for transporting sugars and nutrients produced during photosynthesis from the leaves to other parts of the plant.

Front

What is the palisade layer in a leaf?

Back

The palisade layer is a layer of tightly packed cells located beneath the upper epidermis of the leaf, containing chloroplasts for photosynthesis.

Front

What is the role of spongy mesophyll in leaves?

Back

Spongy mesophyll is a layer of loosely arranged cells in the leaf that facilitates gas exchange and contains air spaces for the movement of gases.

Front

What are vascular bundles in plants?

Back

Vascular bundles are structures in plants that contain both xylem and phloem, facilitating the transport of water, nutrients, and food.

Front

What is the primary function of xylem in plants?

Back

Xylem is a type of vascular tissue responsible for transporting water and dissolved minerals from the roots to the rest of the plant.

Front

How do stomata regulate water loss in plants?

Back

Stomata can open and close to regulate the amount of water vapor that escapes from the leaf, helping to maintain water balance.

Front

What is the difference between xylem and phloem?

Back

Xylem transports water and minerals upward from the roots, while phloem transports sugars and nutrients downward from the leaves.

Front

What is the significance of chloroplasts in the palisade layer?

Back

Chloroplasts in the palisade layer are essential for photosynthesis, as they capture sunlight and convert it into chemical energy.

Front

What is the role of the epidermis in leaves?

Back

The epidermis is the outer layer of cells that protects the leaf and helps reduce water loss.
