Multiple choice

Which of the following tissues is present in the husk of coconut?

  1. Sclerenchyma

  2. Chlorenchyma

  3. Aerenchyma

  4. Meristematic tissue
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Sclerenchymatous tissue is present in the husk of coconut, which comprises of dead cells with thickened cell walls due to deposition of lignin and hemicellulose. This makes husk of coconut hard and stiff. That is why it is difficult to remove.

Multiple choice

Which of the following is not a characteristic feature of ferns?

  1. They have true roots, stems and leaves.

  2. They are predominantly land plants.

  3. They produce flowers and seeds.

  4. Their leaves are divided into leaflets.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Ferns do not produce flowers and seeds. They reproduce by spores, which grow on the lower surface of leaves.

Multiple choice

Which among the following statements is incorrect?

  1. Dodder is a common parasitic angiosperm.

  2. The leaves of Indian spinach are thick due to storage of water.

  3. Saprophytic plants feed on living plants.

  4. Autotrophic plants prepare their own food with the help of chlorophyll and sunlight.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Saprophytes are plants, which derive food from dead and decaying plant or animal matter.

Multiple choice

Coconut husk is an example of which of the following tissues?

  1. Sclerenchyma

  2. Collenchyma

  3. Chlorenchyma

  4. Aerenchyma

  5. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Yes, it is correct. The cells here are dead and intercellular space is absent. It presents structural rigidity to plant parts. Coconut husk is an example of this tissue.
