Leaf practice questions

Front

What is the cuticle in a leaf?

Back

The cuticle is a waxy layer that covers the surface of the leaf, helping to prevent water loss.

Front

What is the outer layer of cells in a leaf called?

Back

The outer layer of cells in a leaf is called the epidermis.

Front

What does phloem transport in plants?

Back

Phloem transports sugar produced during photosynthesis from the leaves to other parts of the plant.

Front

What is the function of the cuticle in a leaf?

Back

The cuticle protects the leaf from water loss and environmental damage.

Front

What is the role of the upper epidermis in a leaf?

Back

The upper epidermis protects the leaf and helps reduce water loss.

Front

What is the palisade layer in a leaf?

Back

The palisade layer is a layer of tightly packed cells in the leaf where most photosynthesis occurs.

Front

What is the spongy mesophyll?

Back

The spongy mesophyll is a layer of loosely arranged cells in the leaf that allows for gas exchange.

Front

What is the function of stomata in leaves?

Back

Stomata are small openings that allow for gas exchange, letting CO2 in and O2 out.

Front

What is the difference between xylem and phloem?

Back

Xylem transports water and minerals from the roots to the leaves, while phloem transports sugars from the leaves to the rest of the plant.

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.
