PHYSIOLOGY
THE CELL
,The Cell
The cell is one of the most basic units of
life.
There are millions of different types of cells.
There are cells that are organisms onto
themselves, such as microscopic amoeba
and bacteria cells.
And there are cells that only function when
part of a larger organism, such as the cells
that make up your body.
, The cell is the smallest unit of life in our
bodies.
In the body, there are brain cells, skin cells,
liver cells, stomach cells, and the list goes on.
All of these cells have unique functions and
features.
And all have some recognizable similarities.
All cells have a 'skin', called the plasma
membrane, protecting it from the outside
environment.
, The cell membrane regulates the movement of water,
nutrients and wastes into and out of the cell.
Inside of the cell membrane are the working parts of the
cell.
At the centre of the cell is the cell nucleus.
The cell nucleus contains the cell's DNA, the genetic
code that coordinates protein synthesis.
In addition to the nucleus, there are many organelles
inside of the cell - small structures that help carry out the
day-to-day operations of the cell.
One important cellular organelle is the ribosome.
Ribosomes participate in protein synthesis.
