To address your query about the type of cell produced by the union of haploid gametes during fertilization, let's break down the options:

1. Somatic cell: This refers to any cell of the body that is not a reproductive cell. Somatic cells are diploid in nature, but they are not a direct product of fertilization.

2. Body cell: This term is often synonymous with somatic cells and is typically used to describe any cell forming the body tissues, excluding germ cells (gametes).

3. Zygote: This is the correct answer. A zygote is the initial cell formed when two gametes (sperm and egg) fuse during fertilization. It is diploid, having received a set of chromosomes from each parent, hence restoring the diploid number.

4. Synapsids: This term typically refers to a group of animals defined by specific anatomical characteristics, particularly in relation to their skull structure, and is not relevant in this context.

5. Sex cell: This term generally describes gametes (sperm and egg), which are haploid, not diploid.

Final Answer

The correct term for the diploid cell produced by the union of haploid gametes during fertilization is zygote.
