Test: Animal Tissues - 1 - Class 9 MCQ

Smooth muscles (ii) and cardiac muscles (iii) are involuntary muscles. Striated muscles (skeletal muscles) are generally under voluntary control.

Lysosomes are called the "suicide bags" of the cell because their enzymes can break down cellular components, and in certain conditions, they can lead to the digestion of the cell itself.

The fluid matrix of blood is plasma. Plasma carries blood cells, nutrients, hormones, and waste products throughout the body.

Cardiac muscles are striated, uninucleated, and branched. They are involuntary muscles responsible for the rhythmic contraction and relaxation of the heart.

Cartilage is not found in the kidney. It is a connective tissue that provides support and flexibility and is found in various parts of the body, including the nose, ear, and larynx.

Multicellular glands are formed by the folding of epithelial tissue. Epithelial tissue forms the lining of glands and ducts.

Ligament, tendon, and blood are examples of connective tissues. Ligaments connect bone to bone, tendons connect muscle to bone, and blood is a type of connective tissue.

Dislocation of bones typically involves the tearing or stretching of ligaments, the tough bands of connective tissue that connect bones to each other.

Contractile proteins, such as actin and myosin, are found in muscles. These proteins enable muscle contraction.

The hard matrix of bone consists of minerals, primarily calcium and phosphorus, which contribute to bone strength and rigidity.

Tissues in a multicellular organism ensure division of labour, where different types of cells perform specific functions, contributing to the overall functioning of the organism.

Epithelial tissue has an exposed outer surface and an inner surface anchored to connective tissue by a thin, non-cellular structure called the basement membrane.

Osteocytes are cells found in bones. They play a role in maintaining bone tissue.

The cells in the intestine with microvilli are specialized for absorption and are columnar epithelial cells.

Areolar connective tissue is a versatile tissue found between the skin and muscles, around blood vessels, and in various other locations. It provides support and flexibility.

Fats are stored in the human body as adipose tissue. Adipose tissue serves as a storage site for fat.

Neurons have a single long part called an axon, which transmits nerve impulses away from the cell body.

Muscular tissue is responsible for movement in the body. It is composed of muscle cells that contract and enable various types of movement, such as voluntary movements controlled by skeletal muscles or involuntary movements in organs like the heart.

The correct answer is A: Striated muscles.

• Striated muscles are also known as skeletal muscles.


• These muscles display a pattern of alternating light and dark bands, called striations.


• This banding is due to the arrangement of actin and myosin filaments within the muscle fibers.


• Smooth muscles and cardiac muscles do not have this distinct banding pattern.

Neurons receive and transmit information in the form of nerve impulses. These impulses travel along the length of the neuron and allow communication between different parts of the nervous system.
