A type of microscope that uses visible light and a system of lenses to generate magnified images of small objects.

A type of cell division that produces genetically identical cells.

A piece of glass or other transparent material with curved sides, used in a microscope to magnify objects.

Making small objects appear larger in order to see more detail.

A point where light rays converge to form an image with clarity.

Observing mitosis in plant cells using a light microscope (including PMAT)

Combined science

Growth in multicellular organisms

The cell cycle and cell division: mitosis (including PMAT)

The structure of DNA: including nucleotides

Errors in cell division and cancer: basics

Making gametes: meiosis

Pupils will learn about unspecialised cells in animals and plants, how they become specialised, and potential benefits and issues with using stem cells in medicine. 

Pupils learned about dominant and recessive alleles, and how to use models of single gene inheritance to make predictions about the genotypes and phenotypes of offspring.

This unit covers mitosis and the cell cycle in growth, cancer as uncontrolled cell division, and the role of mutations in genetic variation. It explains meiosis in gamete formation and chromosome reduction. The emphasis is on recording observations and interpreting patterns to draw conclusions.

Cell division: mitosis and meiosis

Which part of the microscope is the line pointing towards?

In which two places does mitosis take place in an onion?

Turn the objective lens to the lowest power.

Clip the specimen onto the stage and turn on the light.

Use the coarse focus wheel to roughly focus the image.

Use the fine focus wheel to get a sharp focus.

Turn the objective lens to a higher power to increase the magnification.

Put these stages in order to show how a microscope should be used?

The image has circled a stage of mitosis, what stage is this?

The image has circled a stage of the cell cycle, what stage is this?

the DNA and sub-cellular structures are copied.

nuclear membrane breaks down & DNA condenses to visible chromosomes.

where the chromosomes line up along the equator of the cell.

chromosomes split to form chromatids that are pulled to either side.

nuclear membrane re-forms; chromosomes decondense back to DNA strands.

cell membrane & cytoplasm divide forming 2 genetically identical cells

Match the stage of mitosis to the correct description

What word describes making objects appear larger using a lens?

What are the smallest living units of life?

What is this piece of scientific equipment called?

A type of cell division that creates four different cells.

The process by which the sex cells are formed.

A type of cell division that creates two genetically identical cells.

Put these stages of mitosis into the correct order

Daughter cells have half the amount of DNA.

Two genetically identical cells are produced.

Multicellular organisms use mitosis for growth and repair.

Which of the following is not true for mitosis?
