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

Biology

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.

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?

Cell growth; DNA and sub-cellular structures are being copied.

Chromosomes are lining up along the middle of the cell.

Cytoplasm and cell membrane are dividing.

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

The cytoplasm and cell membrane are dividing.

The chromosomes are being pulled to either end of the cell.

The DNA is decondensed and held within a nucleus.

The DNA has condensed to form visible chromosomes.

The nuclear membrane is formed around the DNA.

Which statements describe what has happened to the circled cell?

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.

DNA and sub-cellular structures are copied.

Chromosomes line up in the middle, are pulled apart. Nucleus divides.

Match each stage of the cell cycle to the description of what happens?

Daughter cells have half the amount of DNA.

Two genetically identical cells are produced.

Multicellular organisms use mitosis for growth and repair.
