Plant Structure and Function Quiz

A waxy layer covering the surface of leaves that prevents water loss and protects against pathogens.

The specialized tissue in plants responsible for transporting water and dissolved minerals from roots to the rest of the plant.

The specialized tissue in plants responsible for transporting sugars (food) produced during photosynthesis from leaves to other parts of the plant.

A band of waterproof material in plant roots that forces water to pass through the endodermal cells, regulating the flow of water and nutrients.

A type of plant tissue that provides flexibility and support to the plant, particularly in young stems and leaves.

The large, central vacuole in plant cells is responsible for storing water, nutrients, and waste products, playing a crucial role in maintaining cell turgor pressure and regulating cell volume.

Parenchyma cells, found throughout plant tissues, are responsible for photosynthesis, food storage, and tissue repair. They are the most common type of plant cell.

Collenchyma cells provide flexibility and support to growing plant parts, particularly stems and leaves. They have thick cell walls, but unlike sclerenchyma cells, they remain alive at maturity.

The dermal tissue is the outer protective layer of a plant, acting as a barrier against environmental damage and disease. It includes the epidermis, which is covered by a waxy cuticle to prevent water loss.

Guard cells are specialized cells that regulate the opening and closing of stomata, tiny pores in the leaves and stems that allow for gas exchange and transpiration.

Trichomes are hair-like structures found on the epidermis of plants, providing protection from insect predation by deterring herbivores and preventing excessive water loss.

Xylem is a type of vascular tissue that carries water and dissolved minerals upward from the roots to the rest of the plant.

Phloem is a type of vascular tissue that carries sugars and other nutrients produced by photosynthesis throughout the plant.
