what is a zygote?
a fertilised diploid egg/ovule
how do zygotes form embryos?
zygotes undergo cell division to form an embryo
fertilisation in animals?
when the nuclei of the haploid sperm and egg fuse together to form a diploid zygote
fertilisation in plants?
when the nuclei of the haploid pollen and ovule fuse together to form a diploid zygote
