Plants are made up of different types of cells.

The diagram below shows a root hair cell and leaf palisade cell. 

What is the name of the structure labelled X?

State the function of structure X.

What is the name of the structure labelled Y?

State the function of part Y.

The root hair cell and the leaf palisade cell are examples of plant cells.

State the similarities and differences between plant and animal cells.

The diagram below shows the structure of an animal cell.

Name structures A to E in the diagram below.

Name two structures found in plant cells that are not present in animal cells.

Describe the function of the structures identified in part b).

Microscopes allow us to observe objects that are too small to view with the naked eye.

Name parts A-D of the light microscope in the photograph below.

State one advantage and one disadvantage of using an electron microscope compared to a light microscope.

A student wants to use this light microscope to observe onion cells.

To prepare her slide, the student took a small piece of onion and peeled off a piece of onion skin.

She then placed the skin flat on the slide, added a drop of iodine solution and covered it with a cover slip, making sure that there were no bubbles.

Describe how the student would use the light microscope to view her slide. 

Explain why the student used iodine solution when she prepared her onion slide.

Both animal cells and plant cells are eukaryotic cells.

Animal and plant cells have differences as well as similarities.

Tick the boxes in the table to indicate whether the structures are found in animal cells, plant cells or both.

Match the organelle to its function.

The diagram below shows a cell.

What type of cell is represented in the figure above?

Name structure X.

Give one function of organelle X.

How is a prokaryotic cell different from the cell in the drawing?

The figure below shows an animal cell observed using an electron microscope with a magnification of x20,000.

Name and label the organelle where aerobic respiration takes place.

Name and label the organelle where you would find the DNA.

Sketch the cell as you would see it if you were using a school light microscope instead of an electron microscope, and label the parts you would be able to identify. 

Microscopes use lenses to magnify objects.

State the equation linking magnification, image size and object size.

The image below is a photograph of a Paramecium (a single-celled protist).

The photograph was taken by a student through an eyepiece of a lab microscope.

The image is 120 mm wide.

The actual size of the Paramecium is 3 × 10^-4 m.

Calculate the magnification of the Paramecium.

The Paramecium is a protist. 

Protists are eukaryotic organisms.

Which of the following organelles does a protist not have?

The figure below shows a bacterial cell and a yeast cell. 

Use the figure above and your own knowledge to compare and contrast the two types of cells.

Select the correct statement(s) about yeast from the list below.

The diagram shows a sperm cell that has been magnified 100,000 times.

Calculate the actual length of the sperm cell. Show your working and give your answer in micrometres.

A flagellum is a microscopic hair-like organelle used by cells and microorganisms for movement.

Eukaryotic flagella, like the ones in sperm cells, are very different from the flagella of prokaryotes such as bacteria.

Give three other differences between animal and bacterial cells.
