Answer:
A frog releases sperm over eggs that were laid by another frog, and these cells fuse together.
A pollen grain from one flower fertilizes another flower, resulting in the development of a seed.
Explanation:
Sexual reproduction can be described as a method of reproduction in which haploid gametes from a male and a female parent unite to form a diploid zygote.
A frog fertilizing an egg present in water is an example of external fertilization. External fertilization means that the fertilization occurs outside the body of the female parent but it is a mode of sexual reproduction.
The pollen grains of a flower fertilizing the egg of another flower is also sexual reproduction.
