Question

Choose the correct option-

A gymnosperm cell has 30 chromosomes in it. What will be the number of chromosomes present in its endosperm?

• A. 60
• B. 20
• C. 15
• D. 10

Answer 1

The correct option is C

15

The correct option is C.

Explanation of Correct option

1. The endosperm is the tissue that surrounds the embryo and provides nutrition.
2. In gymnosperms, one nucleus degenerates, thus lacking a true endosperm.
3. It is pre-fertilized tissue and haploid in number.
4. In the above statement, the gymnosperm cell has a total of 30 chromosomes (diploid number).
5. Thus, the endosperm will have half of the diploid number or 15 chromosomes.

Final answer: The total number of chromosomes in the endosperm of the given gymnosperm plant is 15.
