Test: Tissue- 1 - Question 1

Chloroplasts occur in which of the following cells?

Detailed Solution for Test: Tissue- 1 - Question 1

Specialized parenchyma cells known as chlorenchyma found in plant leaves contain chloroplasts. This allows them to perform a photosynthetic function and responsible for the storage of starch. 

So, the correct answer is 'Chlorenchyma and parenchyma.'

Test: Tissue- 1 - Question 2

In desert plants, the rate of water loss gets reduced due to the presence of__________.

Detailed Solution for Test: Tissue- 1 - Question 2
  • Cuticle is a protective, hydrophobic waxy covering produced by epidermal cells of leaves, young shoots and other aerial parts.
  • It minimizes the water loss through transpiration (with the help of stomata) and reduces pathogen entry.
Test: Tissue- 1 - Question 3

Lignified or thickened cell wall is a characteristic feature of______.

Detailed Solution for Test: Tissue- 1 - Question 3

Sclerenchyma cells have thickened lignified walls, which make them strong and waterproof. They are commonly classified into support types and conducting forms. Support sclerenchyma is comprised of sclereids and fibers.

Test: Tissue- 1 - Question 4

Which of the following tissues has dead cells?

Detailed Solution for Test: Tissue- 1 - Question 4
  • Sclerenchyma cells are the permanent tissues present in the plants.
  • They provide hardness and stiffness to the plant and are composed of dead cells.
  • This tissue is present in stems around vascular bundles in the veins of leaves and in hard covering of seeds and nuts.
Test: Tissue- 1 - Question 5

Bones are connected to muscles at the joints by______.

Detailed Solution for Test: Tissue- 1 - Question 5
  • Tendons connect muscles to bones. Tendons (another type of tough connective tissue) on each side of a joint attach to muscles that control the movement of the joint.
  • Ligaments connect bones together.
Test: Tissue- 1 - Question 6

Voluntary muscles are found in______.

Detailed Solution for Test: Tissue- 1 - Question 6

Limbs are the voluntary muscles because we can completely control them.

Test: Tissue- 1 - Question 7

The columnar epithelial cells possess cilia in______.

Detailed Solution for Test: Tissue- 1 - Question 7

Ciliated columnar epithelium moves mucus and other substances via cilia and is found in the upper respiratory tract, the fallopian tubes, the uterus, and the central part of the spinal cord.

Test: Tissue- 1 - Question 8

Select the incorrect sentence.

Detailed Solution for Test: Tissue- 1 - Question 8

A tendon is a flexible but inelastic cord of strong fibrous collagen tissue attaching a muscle to a bone.

Test: Tissue- 1 - Question 9

Both collenchyma and sclerenchyma give mechanical strength to plants; but the former differs from the latter, in_______.

Detailed Solution for Test: Tissue- 1 - Question 9
  • Sclerenchyma are dead cells hence they don't possess protoplasm at maturity in the same way as phloem sclerenchyma have.
  • But due to lignified cell wall at the corner, they are not able to expand more hence they don't lose protoplasm.
Test: Tissue- 1 - Question 10

Cork cells are made impervious to water and gases by the presence of_______.

Detailed Solution for Test: Tissue- 1 - Question 10

The walls of cork cells are heavily thickened with an organic substance, suberin. Suberin makes these cells impervious to water and gases.
