I was reading about how amoebas move, and it mentioned something called ectosarc.
Sloth B
Oh really? I think I've heard of that before, but I'm not exactly sure what it is.
Sloth A
Yeah, it's like the outer part of their cytoplasm that helps them change shape.

Ectosarc → It is formed from "ecto-" (from Greek "ektos", meaning outside) and "sarc-" (from Greek "sarkos", meaning flesh). The word "ectosarc" refers to the outer layer of protoplasm in a cell, literally meaning outside flesh.

Memory Tip
