The embryonic stage you are referring to is called the blastocyst stage. During this stage, the embryo is a hollow sphere of cells with an inner cell mass that will eventually develop into the fetus.
The development at an early stage for humans is called embryonic development, for pets is called embryonic or fetal development, and for petunias is called seed germination and seedling development.
The developing cells before they are considered an embryo are called blastomeres. These are the cells that form during early stages of embryonic development through the process of cleavage.
The period during embryo development when the embryo is alive but not actively growing is called the embryonic diapause. This is a state of suspended animation that allows the embryo to delay development until environmental conditions are more favorable for survival.
The correct answer to this question is optic vesicles.
The modified leaves that are found in embryonic plants are called cotyledons. Cotyledons are the first leaves produced by the plant. They are not true leaves and are considered to be seed-leaves because they are a part of the seed or embryo of the plant.
A solid ball of cells is called a morula. A morula is an embryo that is at an early stage of embryonic development.
A rudimentary seed is called an embryo. It consists of the basic structures needed for the plant to grow, such as the embryonic root and shoot.
