Cytoplasm
A nucleus
A cell membrane
A typical plant cell is shown in the diagram.
Identify the labelled part shown.
Cell wall
Cytoplasm
Nucleus
Vacuole
The diagram shows a typical animal cell.
Which part of the cell is used for the temporary storage of food, water and waste?
Vacuole
Chloroplast
Mitochondrian
Nucleus
The diagram shows a typical plant cell.
The jelly-like substance in a cell which contains dissolved materials is known as
cytoplasm
chlorophyll
the cell wall
mitochondria
The diagram shows a typical plant sell with the cell wall labelled.
One of the functions of the cell wall is to
give the plant its shape.
control cell activities.
allow respiration to take place.
store nutrients.
Energy needed for movement and growth is produced by a process called respiration.
This takes place in a part of the cell called
mitochondria
the nucleus
chloroplasts
cytoplasm
The picture shows a group of similar cells.
A group of similar cells that have a shared function is known as
tissue
a system
cytoplasm
an organ
Which one of the following shows a nerve cell?
Roots are under the soil and so do not get much sunlight. Photosynthesis cannot take place without sunlight.
This means that root cells usually have
very few chloroplasts.
the same number of chloroplasts as other types of plant cells.
a large number of chloroplasts.
very small vacuoles.
The smallest cell in the male human body is
Which one of the following statements is incorrect?
Animals can make their own food.
Animals do not contain chlorophyll in their cells.
Animals cannot carry out photosynthesis.
The cells in animals do not contain cell walls.
Stem cells can be removed from living organisms and used for medical purposes to generate new tissue in humans.
Which one of the following stem cells causes social and ethical issues as to their use?
Embryonic stem cells
Umbilical cord stem cells
Bone marrow stem cells.
When viewing an object using the high power objective lens, which of the following should you NOT use first as it may cause the objective lens to touch and damage the slide?
The highest power lens
The lowest power lens
The fine focus wheel
The course focus wheel
The picture shows some onion cells which were viewed with a microscope.
When viewing some onion cells using a microscope, which focus wheel should be turned first?
The coarse focus wheel
The fine focus wheel
It does not matter
Which two parts of a microscope combine to give a magnified view of a cell?
Eyepiece and objective lens
Eyepiece and focus knob
Light source and objective lens
Stage and eyepiece
When viewing a sample of onion cells using a microscope, the student placed the cells on a slide and then placed a coverslip over it.
What is the purpose of the coverslip?
To keep the cells flat.
To get a better view of the cells.
To stop the onion cells from degrading.
So the onion cells do not fall off the slide.
There are usually three objective lenses on a typical microscope as shown.
Which of these objective lenses should you first use to focus on the object?
The lens with the lowest magnification
The lens with the highest magnification
It does not matter
On a typical microscope, there is a rotating part containing three different objective lenses.
What is this part called?
Nosepiece
Stage
Eyepiece
Focus knob
The photo shows part of a microscope which contains the stage.
What is the function of the stage on a microscope?
To hold the slide in place
To magnify the size of the image
To reflect light onto the image
To view the image more clearly
The diagram shows a microscope.
What is the part of the microscope labelled In the diagram, and what is its function?
The coarse adjustment, and its function is to allow you to see a clear, magnified image.
The coarse adjustment, and its function is to hold the glass slide.
The objective lens, and its function is to allow you to see a clear, magnified image.
The mirror, and its function is to shine light on the glass slide.
The stage, and its function is to hold the glass slide.
When looking at onion cells under a microscope, a thin slice of onion tissue is placed on a slide, and a small drop of dye is then placed on the tissue.
What should be done next?
A coverslip should be placed over the onion tissue.
The coarse focus should be adjusted until the cells become visible.
The onion should be cut into thin slices.
A drawing of the onion cells should be made.
You should have observed onion cells under the microscope in the laboratory.
Which one of the following images shows onion cells as they would appear to you when viewed using a microscope?
When viewing onion cells under a microscope, a few drops of a certain solution are added to stain the cells and show these cells more clearly.
Select the correct solution that you should use from the list below.
Iodine solution
Soap solution
Salt solution
Sugar solution
