Onion root cells are diploid.
Onions, like most plants, are diploid organisms. This means their cells, including the root cells, contain two sets of chromosomes. Specifically, onion root cells have a total of 16 chromosomes (2n = 16). Each parent contributes one set of 8 chromosomes.
Here's a breakdown:
- Diploid (2n): Possessing two complete sets of chromosomes, one from each parent.
- Haploid (n): Possessing only one complete set of chromosomes, as found in gametes (sperm and egg cells).
In the case of onions, only the reproductive cells (gametes) are haploid. The somatic cells, like those in the roots, are diploid, ensuring the plant's genetic stability and proper development.
