Animal Tissues - 2 - Free MCQ Practice Test with solutions, Class 9

Tissues are groups of cells with similar structures and functions working together to perform specific tasks in the body.

Adipose tissue is a specialised form of connective tissue designed for storing energy in the form of fat. It plays a crucial role in:

• Energy metabolism
• Cushioning various body parts

Skeletal muscles are responsible for voluntary movements because:

• They are attached to bones.
• They are under conscious control.

This enables actions such as:

• Walking
• Running
• Writing

Cardiac muscle cells are:

• Cylindrical in shape
• Have branching interconnections
• Facilitate synchronized contraction

Each cardiac muscle cell typically contains:

• A single nucleus

This distinguishes them from skeletal muscle cells, which are:

• Long and cylindrical
• Multinucleated due to the fusion of multiple cells during development

The axon is the long extension of a neuron that transmits signals away from the cell body to other neurons, muscles, or glands. It plays a crucial role in neural signalling by conducting action potentials over long distances.

Tendons are the connective tissues responsible for:

• Attaching muscles to bones
• Enabling movement
• Facilitating the transfer of muscle forces to skeletal parts

While ligaments also connect structures, they specifically:

• Link bones to other bones
• Do not connect muscles

Squamous epithelial tissue is specifically known for forming barriers that protect and separate different body systems, such as the lining of the skin and organs. This type of tissue is characterized by its flat, layered cells which provide effective protection against external factors.
