What is a term used to describe an embryo 8 weeks after fertilization?
Well, it seems like after the 8th week it's called a fetus, but before it's just an embryo.
At what stage does an embryo become larger than the zygote?
After cleavage finishes, the cell cycle continues as normal - cell division slows, yet cells grow in size instead of just continually dividing. This is when gastrulation begins (the in-folding of the hollow blastula into multiple germ layers forming the ectoderm, mesoderm, and endoderm).
Why is the growth of the embryo different from the growth of the fetus?
Once the zygote becomes an embryo it starts developing all of its organs, nervous system etc. then after 8 weeks of development everything is there so it becomes a fetus, and the fetus just grows bigger.
What is the degree of fetal development that has occurred by the end of the first trimester?
The first stage of fetal development is the embryo stage. This is basically just the point where there are two layers of cells. From this point, the cells begin to divide, and several cells are created and begin forming the organs of the infant.

What is the cost for just transfering frozen embryo's, as I already have embryo's in storage.?
A lot of business will transfer your embryo for free. It is good buisness practice. They figure that if they can get your embryo they will make money off the storage. Check into local businesses and see which of these offer you this convienence.

What is an embryo of a plant?
it is just like the unborn animal that is zygote,or plant embryo is undeveloped young plant.which may change into a plant if it gets favorable condition to germinate.
What is the primitive streak?
To my understanding the basic function of the primitive streak is to provide a pathway for pluripotent cells to migrate to different areas of the embryo. This is how neural tubes are formed, leading to neural folds and the neural groove. Which eventually gives rise to the formation of the brain, spinal cord and the autonomic portion of the peripheral nervous system. However if it wasn't for the primitive streak, the formation of the embryo itself would be impossible since everything comes from pluripotent cells. I guess the "function" just depends on on what part of development you are referring to.
What is a stage without stage direction?
It's just a stage. You cant have anything without stage directions
