• Foetus $\longrightarrow$stage when organs can be identified externally

• Amoeba $\longrightarrow$ Binary Fission

Explanation-

☆1st☆

• Zygote $\green\longrightarrow$ fusion of male and female gametes

Zygote is formed when the male and female reproductive cells fuse.

And then zygote develops into embryo.

☆2nd☆

• Hydra $\green\longrightarrow$ Buds

In fishes, fertilization takes place externally.

The female fish discharges the eggs in the water and the male discharges the sperms. The sperms swim with the help of tail and fertilizes the egg.

☆5th☆

• Foetus $\green \longrightarrow$stage when organs can be identified externally

In female pregnancy, eight weeks after fertilization the embryo develops body parts and that stage of the embryo in which all the body parts can be identified is called foetus.

☆6th☆

• Amoeba $\green\longrightarrow$ Binary Fission

Amoeba is a single-celled organism that reproduces by binary fission.

✴Binary fission is the splitting of cells into two almost identical cells.
