Does embryonic development mean the same as fetal development?
No. The embryo and the fetus are two separate stages in a baby's prenatal development.
Why is it useful for scientists to look at embryonic structures when determining evolutionary relationships?
Sometimes there are similarities in the embryonic stages of organisms that don't exist in the adult stages.
Neural tissue is formed by the?
Ectoderm is responsible for the formation of neural tissue. It is one of the three main layers of germ cells in the early stages of embryonic development.
What happens during the embryonic period of pregnancy?
The embryonic period are the first eight weeks of development of the child, beginning with fertilization. During this period, the embryo undergoes an amazing transformation from a single cell to a recognizably human embryo. In the mid-twentieth century, George Streeter devised a commonly used embryo classification system by dividing the embryonic period into 23 stages. The embryonic period is followed by the fetal period, which encompasses the remainder of theprenatal development.
What is an organism in the early stages of development?
An organism in the early stages of its development is an embryo.

What is embryological developement?
Embryological development is the development of an embryo. An embryo is the beginning stages of life. Humans, other animals and some plants have the embryonic stage.
Is trophoblastic nutrition preembryonic stage of development?
No, it is part of the embryonic and fetal stages of development. After implantation, the conceptus is fed by trophoblastic nutrition. This is the dominate mode of nutrition for 8 weeks.
Why is it useful for scientists to look at embryonic structures when determining evolutionary relationships?
Sometimes there are similarities in the embryonic stages of organisms that don't exist in the adult stages.
