Name of Cell Part
Description/Function of Cell Part
It has phospholipid molecules & controls access to & from the cell
It has a porous double membrane & controls the cell activities
It is attached or unattached in the cytoplasm and produces proteins
It is rough or smooth& transports material through tubes thast are
connected together in the cytoplasm
It has tubes that are NOT connected together in the cytoplasm and it
packages material like protein to be excreted from the cell.
They’re vacuoles with digestive enzymes & found only in animal
cells
It is a double membrane structure & produces energy from glucose
It is double membrane structure & packages energy into glucose
It is a huge vacuole in the cytoplasm & found only in plant cells

Name :
2.
State the difference between a simple light microscope and a compound light
microscope. (1)
SL has only one objective and CL has more the one objective
3.
Explain the term MAGNIFICATION. (1)
The increase in size of an image
4.
Explain the term RESOLUTION. (1)
The increase in clarity of the image
5.
How does a light microscope use light to produce an image after passing the
light through the specimen? (1)
The light passes through a series of lenses which expand the image before
it reaches your eye.
6.
How does an electron microscope use electrons to produce an image after
passing the electrons through the specimen? (1)
The electrons pass through a series of magnetic fields which expand the
image before it reaches a monitor. You watch the monitor.
7.
How is the image from a transmission electron microscope different to the
image from a scanning electron microscope? (1)
A TEM image is more magnified but the SEM image is 3-D
