The plasma membrane needs lipids, which make a semi-permeable barrier between the cell and its environment. It also needs proteins, which are involved in cross-membrane transport and cell communication, and carbohydrates, which decorate both the proteins and lipids and help cells recognize each other. Hope this helps :)

Fertilization and formation of the zygote occur Within the body of mosquito.
Zygote, from the Ancient Greek (zygtós), "attached, yoked," from (zygoun), "to join, to yoke," A fertilization between two gametes produces a eukaryotic cell. The genome of a zygote, which consists of the DNA from each gamete, is what makes up a new individual creature and holds all of its genetic material.
The zygote is the first developmental stage in animals with many cells. When an egg cell and sperm cell unite to produce a new, distinct organism, a zygote is created in humans and the majority of other anisogamous species. With the aid of mitosis, the zygote can divide asexually in single-celled organisms to create identical progeny. The chloroplast DNA (cpDNA) of a Chlamydomonas zygote is inherited uniparentally from the parent with the mt+ mating type; as a result, such cells are typically uncommon. The mapping of chloroplast genetics through recombination was made possible by these uncommon biparental zygotes.
