When a sperm cell and egg cell come together.
The correct answer is: When a sperm cell and egg cell come together.
The correct answer is: When a sperm cell and egg cell come together.
To arrive at this answer, you can eliminate the other options by understanding the definitions of the terms given.
- The process of pollen moving from place to place: This describes the process of pollination, which is different from fertilization. Pollen transfer is the movement of pollen from a male reproductive structure (anther) to a female reproductive structure (stigma) in flowering plants.
- When an animal is attracted to a flower: This describes an animal's behavior, possibly for the purpose of obtaining nectar or pollen, but it does not refer to fertilization.
- The changes that occur in organisms over time: This describes the process of evolution, which is unrelated to the specific act of fertilization.
That leaves us with the option "When a sperm cell and egg cell come together," which accurately describes fertilization. Fertilization is the union of a sperm cell (male gamete) with an egg cell (female gamete) to form a zygote, initiating the development of a new organism.
