What environmental factors have an adverse effect on the development of the embryo?

Embryos can be both plant and animal. But unfavorable conditions overlap in one way or another. First of all, the temperature. For the normal development of the embryo, a kind of stable temperature is required. A plant embryo needs moisture, sunlight and nutrients. For an animal embryo, it is necessary to have favorable living conditions for the mother’s organism. Any deviation or lack of certain substances can cause a failure in the development of the embryo or stop its development in principle.
