Flatten the specimen
By turning the focussing wheel until the image is
clear
The material that you are looking at.
So light can pass through it so that you can see
it clearly
So that you can see the details more clearly
The objective lens
The eyepiece lens
On the stage
A piece of clear class to put the specimen on
A coverslip.
They are too small. (1-2µm)
Electron microscopes
The nucleus
It surrounds the cell controls what enters and
leaves the cell
It is a jelly-like substance where most of the
chemical process take place
They release energy for the cell through the
process of aerobic respiration
The cell wall supports the cells and strengthens
it.
To make food for the plant by photosynthesis
chlorophyll
It stores cell sap and keep the cell firm

working together to perform
an important job

To carry electrical signals around the body
It is very long and has connections at each end
so that it can join other nerve cells
To swim to an egg cell and fertilise it.
A sperm has a tail so that it can swim. It has a
pointed head so it can pierce an egg cell.

They are packed with lots of chloroplasts.
To absorb water and mineral ions for the plant
In the tips of plant roots
They have a large surface
