If the synergid of an ovule contains 24 chromosomes, then what will be the number of chromosomes in its endosperm?
- A$24$
- B$48$
- Correct answerC$72$
- D$96$
Solution
Synergids are haploid cells present in the embryo sac of an angiosperm.
Thus, the haploid chromosome number is $n = 24$.
The endosperm in angiosperms is formed by triple fusion and is typically triploid ($3n$).
Number of chromosomes in the endosperm = $3n = 3 \times 24 = 72$.
Answer: $72$
Thus, the haploid chromosome number is $n = 24$.
The endosperm in angiosperms is formed by triple fusion and is typically triploid ($3n$).
Number of chromosomes in the endosperm = $3n = 3 \times 24 = 72$.
Answer: $72$
Hence, the correct answer is option: 'C'.
