Question

A mature embryo sac HAS THE FOLLOWING



A)7 CELLS 7 NUCLEI

B)8 NUCLEI 7 CELLS

C)6 CELLS 6 NUCLEI

D)MANY CELLS AND NUCLEI​

Answer 1

Hola, friends ☺️

8 NUCLEI 7 CELLS IS REQUIRED ANSWER

=>The Number of cells = 3 antipodal cells + 2 synergids + 1 egg cell + 1 central cell= 7 cells. BUT the CENTRAL CELL HAS TWO POLAR NUCLEI IN IT. Therefore total number of nuclei = 7 + 1 extra in central cell= 8 nucleate.

Answer 2

8 NUCLEI 7 CELLS IS REQUIRED ANSWER

=>The Number of cells = 3 antipodal cells + 2 synergids + 1 egg cell + 1 central cell- 7 cells. BUT the CENTRAL CELL HAS TWO POLAR NUCLEI IN IT. Therefore total number of nuclei = 7+ 1 extra in central cell= 8 nucleate.
