MCQ
Two nuclei with one cell are found in
- AAntipodal cell
- BChalazal cell
- ✓Central cell
- DSynergid cell
✓
Answer
Correct option: C.
Central cell
c
Central cell.Six out of the eight nuclei are surrounded by cell walls and organized into cells (egg cells and antipodal cells) and remaining two nuclei called polar nuclei are situated below the egg apparatus in large central cell. Thus, a typical angiospermic embryo sac at maturity is $8- nucleate$ and $7-celled$.Mature embryo sac
