Origin of Life, Plant Structures and Funcions

Front

What is the function of guard cells in a leaf?

Back

Guard cells control the opening and closing of the stoma, regulating gas exchange and water loss.

Front

What adaptation helps a plant survive in low sunlight conditions?

Back

Large leaves increase the surface area for capturing sunlight, enhancing photosynthesis.

Front

What is the primary role of leaves in plants?

Back

Leaves provide a place for photosynthesis to occur, converting sunlight into energy.

Front

What is the function of xylem in plants?

Back

Xylem transports water and minerals from the roots to the leaves.

Front

What is the main purpose of seeds in flowering plants?

Back

Seeds protect and distribute the zygote, ensuring the continuation of the species.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to synthesize foods from carbon dioxide and water.

Front

What role do roots play in a plant's survival?

Back

Roots absorb water and nutrients from the soil and anchor the plant in place.

Front

What is the cuticle in plants?

Back

The cuticle is a waxy layer that covers the leaves and stems, helping to prevent water loss.

Front

How do stomata function in plants?

Back

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

Front

What is the role of chlorophyll in photosynthesis?

Back

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