What is the function of phloem in a plant?

Back

Phloem carries food and sugars throughout the plant.

Front

What is the role of guard cells in leaf structure?

Back

Guard cells control the opening and closing of the stomata.

Front

What is the palisade mesophyll?

Back

The palisade mesophyll is a layer of cells in the leaf where most photosynthesis occurs, containing many chloroplasts.

Front

What are stomata?

Back

Stomata are small openings on the leaf surface that allow for gas exchange (CO2 in, O2 out).

Front

What is the epidermis in leaf structure?

Back

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

Front

What is the cuticle?

Back

The cuticle is a waxy layer on the leaf surface that reduces water loss.

Front

What is the spongy mesophyll?

Back

The spongy mesophyll is a layer of loosely packed cells in the leaf that facilitates gas exchange and contains air spaces.

Front

How do xylem and phloem differ in function?

Back

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

Front

What is the importance of chlorophyll in leaves?

Back

Chlorophyll is the pigment that captures light energy for photosynthesis.

Front

What is the main purpose of photosynthesis?

Back

Photosynthesis converts light energy into chemical energy in the form of glucose.
