because the egg and sperm cell combine to reproduce:
Cells combine to create a baby through a process called fertilization. During sexual reproduction, a sperm cell from a male and an egg cell from a female join together in a process called fertilization. This forms a zygote, which is the first cell of a new organism. The zygote then undergoes cell division and development to eventually form a baby.
Gametes are sex cells such as sperm and egg so they MUST be haploid because when they combine to make a baby the baby has one full set of chromosomes. not 2.
Molecules.
cells !! :)Cells combine to form tissues, which combine to form organs, which combine to form systems, which combine to form the body.
cells combine to form a tissue.
yes
a baby
A parent has cells in their body and when parents have sexual relationship they combine,and then the mother goes in to labor and has their baby..
A sperm and an ovum (egg) are the two cells that combine to create a person. Fertilization is when these two cells combine.
Gametes are sex cells such as sperm and egg so they MUST be haploid because when they combine to make a baby the baby has one full set of chromosomes. not 2.
merge cells
It becomes a baby. They go through something called mitosis where the cell gets copied in to two. Then it continues the process and basically make a organ and different organs make up baby !

A sperm cell and an egg cell. They combine to make a baby with full chromosomes.
