Question

What is the ploidy level of a sporophyte in angiosperms?

• A. n
• B. 2n
• C. 3n
• D. 4n

Hint:

Sporophyte = 2n, Gametophyte = n in alternation of generations.

Answer 1

The Correct Option is B

Step 1: Recall alternation of generations.
In plants, life cycles alternate between:
- Gametophyte (n): haploid, produces gametes.
- Sporophyte (2n): diploid, develops after fertilization and produces spores via meiosis.
Step 2: Apply to angiosperms.
In angiosperms, the zygote (2n) divides mitotically to form the sporophyte, which is diploid (2n).
Step 3: Conclusion.
The ploidy of a sporophyte in angiosperms is diploid (2n).
Final Answer: \[ \boxed{\text{Sporophyte in angiosperms is diploid (2n).}} \]
