Leaf Structure

Front

What role do plants play in food chains?

Back

Plants are producers, meaning they create their own food through photosynthesis and serve as the primary source of energy for other organisms in the food chain.

Front

What is the function of guard cells in leaves?

Back

Guard cells regulate the opening and closing of stomata, controlling gas exchange and water loss in the leaf.

Front

What structure in leaves helps prevent water loss?

Back

The cuticle is a waxy layer that covers the leaf surface, reducing water loss and protecting the leaf.

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

How do gases enter and leave the leaf?

Back

Gases like carbon dioxide and oxygen enter and leave the leaf through small openings called stomata.

Front

What is the palisade mesophyll?

Back

The palisade mesophyll is a layer of tightly packed cells in the leaf where most photosynthesis occurs due to high chlorophyll concentration.

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 and contains air spaces.

Front

What is the function of vascular tissue in leaves?

Back

Vascular tissue, consisting of xylem and phloem, transports water, nutrients, and sugars throughout the plant.

Front

What are stomata?

Back

Stomata are small openings on the leaf surface that allow for gas exchange and transpiration.

Front

What is the significance of chlorophyll in leaves?

Back

Chlorophyll is the green pigment in leaves that captures light energy for photosynthesis.
