Morphology

ectoplasm = plasm (transparent) = ecto + plasm

Directly composed of 'ecto-' (outer) + 'plasm' (substance) and describes the outer layer of cytoplasm in cells.

Etymology

Ectoplasm comes from the Greek parts ecto- meaning 'outside' and plasma meaning 'something formed' or 'substance' (the same plasma you see in 'blood plasma'), so in biology it names the clear outer layer of a cell — the 'outside substance' that helps give the cell its shape.
