Column I | Column II | ||
A. | Aleurone layer | 1. | Nutrition |
B. | Parthenocarpic fruit | 2. | Without fertilization |
C. | Ovule | 3. | Seed |
D. | Endosperm | 4. | Double fertilization |
Answer:
(a) It is the
correct sequence of the options in the two columns.
Aleurone layer
surrounds the tissue of monocot seed and morphologically andbiochemically
distinct from seed. It is a protein aceous layer (surrounding theendosperm and
separating embryo) which provides nutrition and helps in germination .
Parthenocarpic
fruit are seedless fruit which develops without the fertilization of egg cell
present in the ovule of the plants.
The ovule cantains
the female reproductive unit, i.e., embryo sac that develop into a seed after
it is fertilized.
Endosperm is
formed during the process of double fertilization by the fusion of one male
gamete with the two polar nuclei at the centre of the embryo sac.
