Well that was the fist discovered cell membrane

it has been discovered that they have a cell wall, cell membrane, mitochondria, chloroplast, endoplasmic reticulum or ER, Ribosomes and many more we learned this in 7thy grade hope this helps.
Cell membrane
A cell membrane is also known as a plasma membrane or cytoplasmic membrane. The cell membrane separates the interior of a cell from its outside environment. The main function of a cell membrane is to protect the cell from its surroundings.
the cell membrane is as flexible barrier outside of the cell.

The cell was discovered by Robert Hooke who had been looking at cork under a microscope. He noticed little "boxes" which he called cells. Infact, the "cells" were part of the membrane of cork cells. It wasn't until the 1830s that cytoplasm was discovered. Before this cell organelles were thought to float around in the cell. Cytoplasm is the "jelly-like" substance that contains all membrane bound organelles. I do not remember the year Robert Hooke discovered cells.
The outer boundary of a general animal cell is the cell membrane.
