Why is study of tissues important?

It helps understand how different body parts work efficiently through division of labour among cells.

What are voluntary and involuntary muscles?

Voluntary muscles act under conscious control; involuntary muscles act without conscious effort.

What are parts of a neuron?

Dendrites, cell body (cyton), and axon.

What is the structural and functional unit of the nervous system?

The neuron is the structural and functional unit of the nervous system.

What is nervous tissue?

Nervous tissue transmits messages between the brain, spinal cord, and body parts.

What are cardiac muscles?

Cardiac muscles are involuntary, branched, and found only in the heart.

What are smooth muscles?

Smooth muscles are involuntary, found in walls of internal organs like stomach and intestines.

What are striated muscles?

Striated muscles are voluntary muscles attached to bones for body movement.

What are the types of muscles?

Striated, unstriated, and cardiac muscles.

What are muscular tissues?

Muscular tissues help in movement by contraction and relaxation.

Tendon connects muscle to bone and helps in movement.

Ligament connects bone to bone and provides flexibility and strength.

Cartilage is a flexible connective tissue present in ear, nose, and joints.

Bone is a hard connective tissue that provides shape, support, and protection to body.

What are the components of blood?

Plasma, red blood cells, white blood cells, and platelets.

Blood is a fluid connective tissue that transports oxygen, nutrients, and hormones.

What is adipose tissue?

Adipose tissue stores fat and provides insulation.

What is areolar tissue?

Areolar tissue joins different tissues and fills spaces between organs.

What is connective tissue?

Connective tissue connects and supports different parts of the body.

What is cuboidal epithelium?

It provides mechanical support and is found in kidney tubules.

What is columnar epithelium?

Columnar epithelium helps in absorption and secretion, seen in small intestine lining.

What is squamous epithelium?

It is a thin flat epithelium found in alveoli and blood vessels allowing diffusion.

What are the types of epithelial tissues?

Squamous, cuboidal, columnar, ciliated, and glandular epithelial tissues.

What is epithelial tissue?

Epithelial tissue forms the outer covering of body organs and lines cavities and glands.

How are animal tissues classified?

They are classified into epithelial, connective, muscular, and nervous tissues.

What are animal tissues?

Animal tissues are groups of similar cells performing specific functions in animals.

Cork is a protective tissue of dead cells formed by cork cambium.

It is the outermost single layer of cells covering the plant body.

What are protective tissues?

Protective tissues like epidermis and cork protect plant surfaces.

What are the components of phloem?

Sieve tubes, companion cells, phloem fibres, and phloem parenchyma.

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

What are the elements of xylem?

Tracheids, vessels, xylem parenchyma, and xylem fibres.

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

What are complex permanent tissues?

Xylem and phloem that help in transport of materials in plant are complex tissues.

What is sclerenchyma?

Sclerenchyma is a dead supporting tissue with lignified walls providing rigidity and strength.

Collenchyma provides flexibility and mechanical support to the plant.

Parenchyma is a living simple permanent tissue that stores food and provides support.

What are simple permanent tissues?

Tissues made of similar cells performing the same function like parenchyma, collenchyma, sclerenchyma.

What are the types of permanent tissues?

Simple permanent and complex permanent tissues.

What are permanent tissues?

Permanent tissues are made of mature cells that have lost the ability to divide.

What is the function of lateral meristem?

It increases the girth or thickness of stems and roots.

Where is apical meristem found?

It is found at root and shoot tips and causes increase in length.

What are the types of meristematic tissues?

Apical, intercalary, and lateral meristem.

What are meristematic tissues?

These are tissues with actively dividing cells responsible for plant growth.

How many types of plant tissues are there?

Plant tissues are of two types: meristematic and permanent tissues.

Who coined the term tissue?

The term 'tissue' was coined by Bichat.

Tissues are groups of similar cells that work together to perform a specific function in plants and animals.

Tissues-True/False

This True/False question set for Class 9 Biology Chapter "Tissues" thoroughly reviews the composition, structure, and functions of both plant and animal tissues. Questions address all key types—meristematic, permanent, epithelial, connective, muscular, and nervous tissues—helping learners distinguish their roles and features. Students can test facts about tissue locations, examples in organisms, and how tissues enable growth, support, protection, transport, movement, and repair in multicellular life. Each question is paired with a clear explanation, fostering solid understanding and meaningful revision for exams or quick quizzes.
