IPA: /ˈɛk.tə.sɑrk/
KK: /ˈɛktəˌsɑrk/
The outer layer of the cytoplasm in certain single-celled organisms, like amoebas, which is involved in movement and feeding.
The amoeba extends its ectosarc to capture food particles from the surrounding water.
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.
Think of 'ecto-' meaning 'outside' and 'sarc-' meaning 'flesh' to remember that 'ectosarc' refers to the outer layer of a cell's protoplasm.
