Three layers develop in an embryo .
yes
the endosperm is in the gymnosperm 'naked seeds' and the angiosperm flowering plants. in gymno - haploid (n) gives nutrients to the embryo the only difference with the angiosperm is that its not haploid (n) but triploid (3n)
there are layers of soft tissue?
Well bones in an embryo aren't really there yet until the embryo becomes multi cellular and more of a child. Even when the embryo becomes more complex the bones are still just cartilage the same material that makes up your nose. Over time a bone cell called osteoblast applies both calcium and phosphate thus the bones become more dense hope i answered your question
ectoderm, more specifically for nervous tissue is neuroectoderm
exosperm
this website stinks it has no answers to my questions
the triploid The endosperm is a nutritive tissue which nourishes the developing embryo. The endosperm in angiosperm is triploid (3n) and it is a post - fertilization structure.
three
yes
3
a falling away of tissue in layers is exfoliation
