Plant spores are usually
select one:
a. haploid

c. tetraploid (4n)
d. dilpoid (2n)

The correct answer will be option- A

Explanation:

Spores are the reproductive unit produced as a result of sexual reproduction and asexual reproduction in both lower and higher plants.

The plant groups like Fungi, Algae, Bryophytes, Pteridophytes and Gymnosperms produce these spores which provides adaptation as they can be dispersed for the long-distance as well as germinate and form an organism.

The spores are formed by the process of sporogenesis which forms four spores from a diploid structure their meiosis which reduces the genetic material to half and maintain the haploid ploidy number.

Thus, option-A is the correct answer.
