Plant Structure and Function

Front

What are collenchyma, parenchyma, and sclerenchyma?

Back

They are types of plant cells that provide support and storage.

Front

What is the function of the epidermis in plants?

Back

The epidermis serves as a protective outer layer of the plant, regulating gas exchange and water loss.

Front

What are stomata?

Back

Stomata are small openings on the surface of leaves that allow gases (like CO2 and O2) to enter and exit the plant.

Front

What hormone is responsible for promoting stem elongation and growth in plants?

Back

Gibberellins are hormones that promote stem elongation and growth.

Front

What role does ethylene play in fruit ripening?

Back

Ethylene is a gaseous plant hormone that triggers the ripening process in fruits.

Front

Define parenchyma cells.

Back

Parenchyma cells are versatile plant cells involved in storage, photosynthesis, and tissue repair.

Front

What is the role of collenchyma cells in plants?

Back

Collenchyma cells provide flexible support to young plant stems and leaves.

Front

What is the function of sclerenchyma cells?

Back

Sclerenchyma cells provide rigid support and strength to mature plant parts.

Front

What is the cortex in plant structure?

Back

The cortex is the outer layer of a plant root or stem, involved in storage and transport.

Front

What is the endodermis?

Back

The endodermis is the innermost layer of the cortex in roots, regulating water and nutrient uptake.
