Question 1

Which type of plant tissue is responsible for the increase in the length of stems and roots?

Accepted Answer

Apical meristem. Apical meristem is found at the growing tips of stems and roots. Its primary function is to facilitate the primary growth or lengthening of the plant body. This tissue consists of actively dividing cells that contribute to the plant's height.

Question 2

The flexibility in plants is primarily due to which simple permanent tissue?

Accepted Answer

Collenchyma. Collenchyma tissue provides mechanical support and flexibility to young plant parts like petioles. The cells are characterized by localized pectin thickening at the corners. This allows plant organs to bend easily without breaking.

Question 3

Which of the following animal tissues connects muscle to bone?

Accepted Answer

Tendon. Tendons are fibrous connective tissues that attach skeletal muscles to bones. They are tough and have limited flexibility compared to other connective tissues. They play a crucial role in transmitting the force of muscle contraction to the bone.

Question 4

Which complex permanent tissue in plants is responsible for the conduction of water and minerals?

Accepted Answer

Xylem. Xylem is the vascular tissue that transports water and dissolved minerals from the roots to the leaves. It consists of four elements including tracheids, vessels, xylem parenchyma, and xylem fibers. This conduction process is largely unidirectional in the plant.

Question 5

The study of the structure and organization of tissues is known as?

Accepted Answer

Histology. Histology is the branch of biology that focuses on the microscopic study of plant and animal tissues. It involves examining how cells are organized to perform specific physiological functions. This field is essential for understanding the overall health and pathology of an organism.
