the part of the plant that attracts insects for pollination is the petals through their attractive colours
The membrane that surrounds the embryo and is filled with fluids that cushions and protects the embryo is called the amniotic sac or amnion.
Yes, the stigma of a flower does not contain food for the embryo. Its main function is to receive pollen grains during pollination and facilitate fertilization. Once pollination occurs, the embryo is nourished by the endosperm in the seed.
The white portion that protects the embryo is called the eggshell. It provides protection and support to the developing embryo and helps maintain the internal environment of the egg.

Pollination ensures the availability of male gametes for fertilization to form zygote for embryo development inside the ovule, that later on becomes a seed.
The amniotic sac is the structure that protects and cushions the embryo during pregnancy. It is filled with amniotic fluid that helps absorb shocks and regulate temperature for the developing fetus.
Seed coat, micropyle, endosperm and embryo are major parts of a seed. The seed coat protects, micropyle allows water to move in, endosperm nourishes the embryo and on germination a new plant emerges from the embryo.
The cotyledon protects the embryo
