False

Explanation:
Detailed explanation-1: -A bryophyte spore is haploid. A haploid cell has one set of chromosomes, a diploid cell has two. In humans, the egg and sperm cells are haploid. When they unite, the resulting cell is diploid and the ensuing embryo continues its development as a diploid individual.
Detailed explanation-2: -Generally non-motile, with some exceptions for male gametes.
Detailed explanation-3: -The male gametes of Bryophytes are motile (biflagellate) and known as antherozoids; the female gametes are non-motile and known as eggs (oosphere). Water is essential for the act of fertilization.
Detailed explanation-4: -So, the correct answer is ‘Zygote undergoes meiosis to produce sporophyte. ‘
