Supporting Tissues in Plants - Free MCQ Practice Test with solutions, JAMB

Collenchyma tissue provides flexible support to the growing parts of the plant, such as young stems and leaves.

Sclerenchyma tissue consists of thick, rigid cell walls that provide strength and support to plant organs, such as stems and roots.

Xylem tissue transports water and dissolved minerals from the roots to the other parts of the plant, primarily in an upward direction.

Phloem tissue is responsible for the transportation of sugars, amino acids, and other organic nutrients throughout the plant.

Plant fibers, such as those found in the stems of hemp and flax, are mainly composed of sclerenchyma cells. These cells provide strength and support.

Xylem tissue contains tracheids and vessels, which are specialized cells responsible for conducting water and minerals throughout the plant.

Phloem tissue is responsible for the movement of food (sugars and organic nutrients) from leaves to other parts of the plant, including the roots, fruits, and seeds.

Collenchyma tissue provides mechanical support to young stems and leaves, enabling the plant to withstand mechanical stress.

Xylem tissue is composed of dead cells. These cells are empty, with no cytoplasm, and their main function is to transport water and minerals.

The phloem tissue, along with the cork cambium, is responsible for the formation of the outer bark in plants.
