Let's review some cell structures.
00:05
First, the cell junctions.
00:08
The cell junctions such as gap junctions, adhesion junctions, tight junctions, all serve the fundamental purpose of linking cells together.
00:27
They help to keep everything in place.
00:34
Next are the chloroplasts.
00:44
Chloroplasts are energy processing molecules, and they use chlorophyll to convert light energy into food energy for the plant cell.
01:08
Plant cells also secrete a substance on the surface of their leaves called the cuticle.
01:16
The cuticle is a waxy substance that coats the leaves and makes them waterproof so that the water that's inside of the leaf cannot get out.
01:36
A structure used for movement is the flagellum.
01:44
Such as in sperm cells.
01:48
The flagella is a cellular extension.
01:52
It is a part of the cell's cytoskeleton...
