I'm sorry, but you'll have to be a bit more specific as to what you want. Unless sentences like the following are useful to you:
"In most vertebrates ectoderm is not lime green in color."
"Ectoderm is not a city in Scotland."
Or, I suppose here's one that might be useful:
"The three germ layers of the early embryo are the ectoderm, mesoderm, and endoderm."
I don't want to make a sentence with the word evolution
From inner to outer, the germ cell layers are the endoderm, mesoderm, and ectoderm. Each of the three layers develops into a different part of the embryo: the endoderm into the respiratory, auditory, and digestive system; the mesoderm into the skeleton and muscles; and the ectoderm into the skin, tooth enamel, and nervous system.
just look up ectoderm by itself you will find it
