I believe so. A zygote is made out of undifferentiated stem cells that specialise into a foetus. So yeah, they're a type of embryonic stem cell

thanks, and are meristem cells same as the stem cells?

Also to add to your last question about a zygote being an embryonic stem cell, you can remember it by knowing that embryonic stem cells come from the embryo

Meristem cells are a type of stem cell found in the growing regions of a plant (just to note, they are not found in animals)

Not quite. Embryonic stem cells usually refers to cells taken from the inner cell mass of a blastocyst (day 5-7 after fertilisation). At this point, cells have already differentiated into either embryoblasts (pluripotent embryonic stem cells), which will form the embryo, or trophoblast cells which will form the placenta and placental membranes.

so the zygote cells divide to multiple cells that form the outer shell of embryo, in which the inner part contains embryonic stem cells? If so, wouldn't it be that embryonic stem cells derived from zygote cell?

for embryo transplant (animal cloning):
when it states that embryo cells are separated into individual cells and each of it form new embryos - does it need to be separated at blastomere (e.g. morula) stage? before these cells specialise into trophoblast cells or embryoblasts (inner mass cells)?

I'm not sure what part of totipotent and pluripotent cells are in gcse spec bcs I defo don't remember that
I'd recommend giving answers to the appropriate academic level 😭
If that really is in the gcse spec I'm baffed af
