In animals, testis is the male reproductive organ that produces sperms. Similarly, in plants, anther is the male reproductive part that produces pollen grains.
(ii) Sperm : Pollen grains
Sperm is a male gamete in animals. In plants, pollens are male gametes. The generative cell of pollen divides to produce two nuclei called male gametes.

In animals, ovary is the female reproductive organ that produces eggs. Similarly, in plants, ovary is the female reproductive organ that contains ovules.

Eggs in animals are also called ova. In plants, eggs are present inside the female gametophyte, i.e., ovule.
