Question:

Answer the question from the diagram of typical anatropous ovule.

Identify the diploid cells present in the ovule:

(A) Outer integument
(B) Antipodal
(C) Nucellus
(D) Synergids

Choose the correct answer from the options given below:

Options:

(A), (B), only

(A), (C), only

(B), (C), only

(B), (D), only

Correct Answer:

(A), (C), only

Explanation:

The correct answer is Option (2) → (A), (C), only

The diploid cells present in the ovule include the following:

  • (A) Outer integument: The integuments are the outer protective layers of the ovule and are made up of diploid cells.
  • (C) Nucellus: The nucellus is the tissue within the ovule that surrounds the embryo sac and is also diploid.

The other options are as follows:

  • (B) Antipodal: These cells are part of the female gametophyte (embryo sac) and are haploid.
  • (D) Synergids: These cells are also part of the female gametophyte and are haploid.

So, the correct answers are: (A) Outer integument and (C) Nucellus.
