________ is the union of the gametes that results in the production of a ________ the fertilized egg.
fertilization; zygote
pollination; embryo
fertilization; haploid cell
meiosis; zygote

Explanation:

• Fertilization: It is the process where male and female gametes (sperm and egg in animals, pollen and ovule in plants) fuse together.
• Zygote: When fertilization occurs, the resulting cell is called a zygote. A zygote is diploid (has a full set of chromosomes, formed from the union of two haploid gametes).
• Pollination: Pollination is just the transfer of pollen (male gamete - like structure in plants) to the female reproductive part (pistil). It is a step before fertilization in plants and does not directly result in a fertilized egg equivalent (zygote in animals, embryo sac fertilization products in plants).
• Embryo: An embryo is formed after the zygote undergoes cell - division and differentiation. It is not the immediate product of gamete union.
• Haploid cell: Gametes are haploid. When they fuse (fertilization), the resulting cell (zygote) is diploid, not haploid.
• Meiosis: Meiosis is the process by which diploid cells (in the reproductive organs) divide to form haploid gametes. It is not the union of gametes.

Answer:

Fertilization; zygote
