Question

In human beings, the largest cell formed during oogenesis is .................

• A. secondary oocyte
• B. 1st polar body
• C. primordial cell
• D. oogonium

Hint:

The secondary oocyte is the largest cell formed during oogenesis, after it has undergone division.

Answer 1

The Correct Option is A

Step 1: Understanding oogenesis.
Oogenesis is the process of egg cell (oocyte) formation in females. During oogenesis, the secondary oocyte is the largest cell formed. It is the primary oocyte that undergoes maturation and division.
Step 2: Analyzing the options.
(A) secondary oocyte: Correct — The secondary oocyte is the largest cell formed during oogenesis.
(B) 1st polar body: Incorrect — The 1st polar body is a smaller cell produced during the division of the primary oocyte.
(C) primordial cell: Incorrect — The primordial cell is the early stage of the oocyte, not the largest cell.
(D) oogonium: Incorrect — The oogonium is the stem cell stage that develops into oocytes, but it is not the largest cell.
Step 3: Conclusion.
The correct answer is (A) secondary oocyte, as it is the largest cell formed during oogenesis.
