Question

l.8.2.a formative 1
which of the following is an example of sexual reproduction?
a piece of a starfish is broken off and grows into a new starfish in a process called regeneration.
a bacterium copies its dna and divides into two daughter cells in a process called binary fission.
a yeast offspring grows out of the body of its parent in a process called budding.
a pollen grain from one flower fertilizes another flower, resulting in the development of a seed.

Explanation:

Sexual reproduction involves the fusion of gametes (like pollen carrying male gametes and the ovule in a flower carrying female gametes) from two parents, leading to genetic variation. Regeneration (starfish), binary fission (bacteria), and budding (yeast) are asexual reproduction methods as they involve a single parent and no gamete fusion. The pollen fertilizing a flower involves two parents (the flower producing pollen and the flower being fertilized) and gamete fusion, so it's sexual reproduction.

Answer:

D. A pollen grain from one flower fertilizes another flower, resulting in the development of a seed. (Note: Assuming the last option is labeled D; if the original options had labels like A, B, C, D, and the last one is the correct one, this is the answer. If the labels were different, adjust accordingly based on the correct option's label and text.)
