What’s in our cells?

This rapid talk is created and voiced by me,Dr Chloe Goldsmith. And reviewed by experts in the field of cellular biology.
I’m sure you’ve heard this before but it is true! Our bodies are amazing! We are made up of millions of different cells
that all work completely different. Sometimes like out of a sci-fie movie. There are cells in our brains called neurons that look
totally different from the cells in our blood. And these also look different from cells in our other organs like, you know, liver.
But even though they all look so different, they are made up of the same components. This is a cartoon of the main
things or sub-units that make up animal cells like ours. In all cells there is a nucleus where our DNA is located. The nucleus is like the brain of the cell.
It’s in control and gives instructions to make things the cell needs to function. Ribosomes are a sub-unit that help decode these instructions from the nucleus
to make proteins. And the endoplasmic reticulum is where these proteins are made based on these decoded messages.
The cytoplasm is where all the cell components are held to protect them. And a cell membrane is a special layer that separates the cytoplasm and the cell components
from the environment surrounding the cell. The mitochondria which are responsible for generating most of the cells’ energy
are located in the cytoplasm, as well as lysosomes, which brake down the things the cell doesn’t need anymore like invaders and germs;
and vacuoles that store things to help the cell maintain water balance. But what do they all look like in a real-life microscope?
This is a video of live liver cells under a microscope. You can see clearly the nucleus, the vacuoles, and the lipid droplets.
Also, the liver is a highly metabolic organ, so there are lots and lots of mitochondria that you can see there too. If you want to know more,
there will be another video out soon, going deeper into some of these cells’ components. But, for now, you’ve all become experts on what is in our cells.
