Question

Identify the labelled parts in the given figure

• A. (i)- Synergids, (ii)- Central cell, (iii)- Vacuole, (iv)- Egg cell, (v)- Antipodals
• B. (i)- Antipodals, (ii)- Polar nuclei, (iii)- Central cell, (iv)- Egg cell, (v)- Synergids
• C. (i)- Vegetative cells, (ii)- Secondary nucleus, (iii)- Egg cell, (iv)- Synergid, (v)- Filiform apparatus
• D. (i)- Anterior cells, (ii)- Central cell, (iii)- Secondary nucleus, (iv)- Female gamete, (v)- Accessory cells

Answer 1

The correct option is B

(i)- Antipodals, (ii)- Polar nuclei, (iii)- Central cell, (iv)- Egg cell, (v)- Synergids

The embryo sac is the female gametophyte in angiosperms. It consists of 7-cells and 8 nuclei at maturity. Three cells present at chalazal end of the ovule are called antipodals. Three cells present at the micropylar end are collectively known as the egg apparatus. Egg apparatus consists of one egg cell and two synergids. In between egg apparatus and antipodals is the central cell which has two polar nuclei.
