Question

Which of the following embryosac is 4 nucleated?
A)polygonum type
B)Oenothera type
C)Allium type
D)Endymion type

Answer 1

polygonum type is a embryosac which is 4 nucleated.

Answer 2

Answer:

Here only the oenothera type of the embryo sac is of 4 nucleated in which the functional megaspore undergoes two successive division to form 4 nucleate embryo.

While in the polygonum type there is the 7 celled 8 nucleate structure in which the monosporic embryosac is 4 nucleate.

The allium type has only two nucleate embryosac.
