Tissues: 17 MCQs with answers

A group of cells with similar structure and function

A tissue is defined as a group of cells that are similar in structure and work together to perform a specific function.

Meristematic tissue

Meristematic tissue is a plant tissue responsible for growth. Nervous, muscle, and connective tissues are animal tissues.

Meristematic tissue

Meristematic tissue consists of actively dividing cells that lead to plant growth.

Parenchyma

Parenchyma is a simple permanent tissue. Meristems are dividing tissues, not permanent.

Epithelial tissue

Epithelial tissue forms the protective covering and lining of body surfaces and cavities.

Connective tissue

Connective tissue includes bone, blood, and cartilage, and it supports and connects different parts of the body.

Muscular tissue

Muscular tissue is made of cells that can contract, enabling movement.

Nervous tissue

Nervous tissue is composed of neurons that transmit electrical impulses.

Meristematic

Meristematic tissue is a plant tissue, not an animal tissue.

False

Some plant tissues like sclerenchyma and xylem vessels are made of dead cells.

True

Epithelial tissue is one of the four main types of animal tissues.

Apical meristem

Apical meristem is a meristematic tissue located at the tips of roots and shoots. Collenchyma, xylem, and phloem are permanent tissues.

Collenchyma

Collenchyma has thick corners and provides flexible support to young stems.

Sclerenchyma

Sclerenchyma cells are dead and have thick lignified walls, providing strength and support.

Cardiac muscle

Cardiac muscle is a specialized muscle tissue found only in the heart, enabling rhythmic contractions.

Xylem

Xylem transports water and minerals from roots to other parts of the plant.

Phloem

Phloem transports food (sugars) from leaves to other parts of the plant.
