In a typical angiosperm, if the number of chromosomes in the endosperm is $3n = 30$, what would be the number of chromosomes in the synergid cells and the antipodal cells respectively?
- A.10 and 10
- B.20 and 10
- C.10 and 20
- D.20 and 20
Show correct answer & step-by-step solution
Correct answer: A — 10 and 10
Solution
- The endosperm is triploid ($3n = 30$), so the haploid number is .
- Synergid cells are part of the egg apparatus and are haploid ().
- Antipodal cells are also haploid ().
- Therefore, both cell types contain 10 chromosomes.
- Hence the answer is (A).
