During the germination of coconut, the major stored food is digested by.

  1. a-amylase

  2. Lipase

  3. Protease

  4. Trypsin

B Correct answer
Explanation

Coconut is an oil seed with an endosperm rich in fats and lipids. During germination, the stored lipids must be broken down by lipases to provide energy and carbon skeletons for the growing embryo.

Monocot seed generally shows

  1. Epigeal germination

  2. Hypogeal germination

  3. Both A and B

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In hypogeal germination, the cotyledons do not come out of the soil surface. In such seeds, the epicotyl (i.e., part of the embryonic axis between plumule and cotyledons) elongates pushing the plumule out of the soil. All monocotyledons show hypogeal germination.

So the correct option is 'Hypogeal germination'.
