The process by which cells divide; this involves a specific set of phases.

A type of cell division that produces genetically identical cells.

A sub-cellular structure that contains the genetic material (DNA); controls the cell activities.

Tightly coiled strands of DNA that carry the genetic material.

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

Biology

Growth in multicellular organisms

Observing mitosis in plant cells using a light microscope (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

What type of cell division produces genetically identical cells in animals?

sexual reproduction in multicellular organisms

repair of tissues in multicellular organisms

Which of the following does **not** involve mitosis?

Put these stages in order to show what happens during the cell cycle. 

In which phase of mitosis is the DNA copied and the cell grows?

nuclear membrane breaks down and chromosomes condense

chromosomes line up along the equator of the cell

chromosomes split and chromatids are pulled to each side of the cell

chromatids decondense and the nuclear membrane reforms

Match each phase of mitosis to the correct description of what happens. 

two genetically identical daughter cells are produced

during interphase the cytoplasm begins to divide

the two main phases are interphase and mitosis

Which statements about the cell cycle are true?

Which sub-cellular structure holds the genetic material in an animal cell?

DNA is wound up tightly to form which structures?

a series of phases a cell undergoes in order to divide

a jelly-like liquid where many chemical reactions occur

surrounds the cell and controls what can enter and exit 

Cell division that produces genetically identical cells is called?

Arrange these in ascending size order from smallest to largest.
