Morphology

blastoderm = blastula (opaque) = blasto + derm

Composed of technical combining forms ('blasto-' and '-derm') whose meanings are specialized biological terms and not transparent to general learners.

Etymology

The word blastoderm comes from Greek parts blasto- meaning 'bud' or 'sprout' and -derm meaning 'skin'. So a blastoderm is like a 'skin' of the very first cells in an embryo, a thin layer that will grow into the body's tissues.
