Spores have two copies of chromosomes.
Spores have three copies of chromosome.
None of the above
Hint:
The number of chromosomes found in gametes.
The correct answer is: Spores have a single set of chromosomes.
Plants and animals have both somatic cells and sex cells.
The somatic cells are diploid containing two sets of chromosomes while the sex cells are haploid having a single set.
Fertilization always occurs between haploid cells. As a result, a diploid zygote is formed.
- Somatic cells are diploid
- Gametes are haploid
