Which of the following statements is true about the structure and function of plant tissues?

  1. Most of the tissues are supportive and dead.

  2. Most of the tissues are supportive and are uniformly distributed.

  3. Most of the tissues are live and uniformly distributed.

  4. Most of the tissues provide mechanical strength and are alive.

  5. Most of the tissues provide mechanical strength and are uniformly distributed.

Show answer
Correct Option: A
Explanation:

It is the property of plant tissues that they provide support and mechanical strength to a plant and are dead in nature.

The parenchyma cells found in aquatic plants are called

  1. chlorenchyma

  2. aerenchyma

  3. collenchyma

  4. sclerenchyma

  5. phloem

Show answer
Correct Option: B
Explanation:

Aerenchyma cells have large air cavities to give buoyancy to the plant and help in floating.

Primary growth in plants is initiated by

  1. apical meristems

  2. lateral meristems

  3. cambium

  4. dermal tissue

  5. intercalary meristems

Show answer
Correct Option: A
Explanation:

They help in lengthwise growth of stem and roots and hence, contribute to the primary growth of stem and roots.

Mature sclerenchyma cells are

  1. thin walled and often contain chloroplasts

  2. lignified and contain no living protoplast

  3. suberised and contain living protoplasts

  4. lignified and contain living protoplasts

  5. lignified and suberised

Show answer
Correct Option: B
Explanation:

The cells of this tissue are dead and the walls are thickened due to the presence of lignin.

Which type of epithelial cells does inner layer of intestines consist of?

  1. Squamous

  2. Columnar

  3. Ciliated columnar

  4. Cuboidal epithelium

  5. Stratified squamous epithelium

Show answer
Correct Option: B
Explanation:

Present in the inner lining of the intestine

The constituents of plasma are

  1. proteins, salts and hormones

  2. calcium and phosphorus compounds

  3. red blood cells (RBCs), white blood cells (WBCs) and platelets

  4. proteins and sugars

  5. None of these

Show answer
Correct Option: A
Explanation:

Plasma constitutes them.

Xylem consists of which of the following elements?

  1. Tracheids, sieve tubes, fibres and companion cells

  2. Tracheids, xylem fibres, companion cells and vessels

  3. Tracheids, xylem fibres, vessels and xylem parenchyma

  4. Tracheids, sieve tubes, fibres and parenchyma

  5. Tracheids, sieve tubes, phloem fibres and vessels

Show answer
Correct Option: C
Explanation:

Xylem consists of tracheids, xylem fibres, vessels and xylem parenchyma as they help in transportation of water and minerals in the plant. Tracheids and vessels are tubular and help in vertical transportation, whereas parenchyma stores food and helps in sideways conduction of water.

Ciliated columnar epithelium forms the lining of

  1. mouth

  2. intestine

  3. respiratory tract

  4. kidney tubules

  5. ducts of salivary glands

Show answer
Correct Option: C
Explanation:

This is where absorption and secretion occurs, as in the inner lining of the intestines, tallciliated columnar epithelium cells are present.

Which simple permanent tissue is thickened at the corner?

  1. Chlorenchyma

  2. Aerenchyma

  3. Collenchyma

  4. Sclerenchyma

  5. Phloem

Show answer
Correct Option: C
Explanation:

The cells of this tissue are living, elongatedand irregularly thickened at the corners.

Corners of Collenchyma are thick due the presence of

  1. lignin

  2. pectin

  3. chloroplast

  4. plastids

  5. chromoplasts

Show answer
Correct Option: B
Explanation:

Present in corners along with cellulose in Collenchyma

Bone cells are embedded in a hard matrix that is composed of

  1. calcium and phosphorus compounds

  2. calcium compounds only

  3. phosphorus compounds only

  4. proteins and sugars

  5. proteins and phosphorus

Show answer
Correct Option: A
Explanation:

Bone cells are embedded in a hard matrix that is composed of calcium and phosphorus compounds

Which tissue makes the husk of coconut?

  1. Parenchyma

  2. Sclerenchyma

  3. Collenchyma

  4. Chlorenchyma

  5. Vascular bundles

Show answer
Correct Option: B
Explanation:

They make the plant hard and stiff since the cells are dead and lignified. Hence, they form the husk of coconut.

Two bones can be connected to each other by which type of connective tissue?

  1. Ligament

  2. Tendon

  3. Cartilage

  4. Areolar connective tissue

  5. Blood

Show answer
Correct Option: A
Explanation:

Two bones can be connected to each other by another type of connective tissue called the ligament.

Main features of striated muscle are

  1. multinucleate with dark and light bands

  2. uninucleate and unbranched

  3. spindle shaped and involuntary

  4. branched and multinucleated

  5. branched and cylindrical

Show answer
Correct Option: A
Explanation:

These are features of striated muscles

Neuron consists of a

  1. nerve cell with cytoplasm and nucleus

  2. nerve cell with short fibres called axon

  3. nerve cell with long part as axon and short branches called dendrites

  4. nerve cell with nerve endings

  5. nerve cell without nucleus

Show answer
Correct Option: C
Explanation:

Complete parts of a Neuron
