Question
Fertilization is the fusion of sperm and egg to make a diploid zygote.
Is the zygote stage unicellular or multicellular?
Solution
The zygote stage is unicellular.
When fertilization occurs, a sperm cell (which is haploid) fuses with an egg cell (which is also haploid) to form a zygote. This zygote contains a full set of chromosomes, making it diploid. Since it results from the fusion of two gametes, the zygote is a single cell at this initial stage of development.
Following the zygote stage, the unicellular zygote begins to undergo mitotic divisions, leading to the development of multiple cells, eventually forming tissues and organs as the organism grows. This transition from a unicellular zygote to multicellular stages is essential for the organism's development.
