Which best describes the life cycles of moss and angiosperm?
jonny [76]

Ans. Option (IV).

Mosses can be defined as non-vascular, flowerless plants that are found in shady or damp regions and reproduce via haploid spores. During reproduction in moss, haploid male gametes or spores are released into surrounding environment that fuse with female spores to form zygote that develop into mature sporophyte.

Angiosperms are vascular, flowering plants that reproduce by seeds. During reproduction in angiosperms, haploid male gametes or pollen grains are released into surrounding environment that fuse with female gametes or eggs to form zygote that develop into seed.

Thus, the correct answer is option (IV).
