Question

2. Single cell formed by the fusion of male and
female gametes
3. Growing of new plants from a few cells in
culture medium​

Answer 1

Explanation:

When the male and female gametes fuse, they become a zygote, which in turn becomes a new embryo containing the full 46 chromosomes – half from the father and half from the mother. This fusion of gametes is called fertilisation. Gametes are formed by a type of cell division meiosis.

Fusion. During sexual reproduction, a male and female gamete will merge together to form a new organism. The two haploid cells will fuse together to form a diploid cell called a zygote.
