In the context of cell division, what is a zygote?
A
A cell that results from the division of a somatic cell during mitosis
B
A mature reproductive cell capable of fusing with another cell
C
A single cell formed by the fusion of two gametes during fertilization
D
A specialized cell that undergoes meiosis to produce gametes

Understand the term 'zygote': A zygote is the initial cell formed when two gametes (sperm and egg) fuse during fertilization. It is diploid, meaning it contains two sets of chromosomes, one from each parent.
Differentiate between the options provided: Analyze each option to determine which one accurately describes the zygote. For example, a zygote is not formed by somatic cell division (mitosis), nor is it a mature reproductive cell (gamete).
Focus on fertilization: Recall that fertilization is the process where two haploid gametes (sperm and egg) combine to form a single diploid cell, which is the zygote.
Clarify the role of meiosis: Meiosis is the process that produces gametes (sperm and egg), but the zygote itself is formed after these gametes fuse, not during meiosis.
Conclude with the correct definition: A zygote is a single cell formed by the fusion of two gametes during fertilization, marking the beginning of a new organism's development.
