Question

The other nuclei of cells within the embryo sac (synergids and antipodal cells) are

• A. Important for fertilization
• B. Important for development
• C. Vestigial
• D. To release food for embryo

Answer 1

The correct option is A Important for fertilization

The egg cell will start the sporophyte generation, if it is fertilized. It is flanked by 2 synergid cells. In almost all angiosperms, they secrete an attractant that guides the pollen tube through the micropyle into the embryo sac. The large central cell which in most angiosperms contains 2 polar nuclei, will after its fertilization develop into the endosperm of the seed. Three antipodal cells are present in the case of the embryo sac of angiosperms.
