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

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.

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

In animals what type of cell division produces genetically identical cells?

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. 

chromosomes lines up along the middle of the cell

DNA and sub-cellular structures are copied

two genetically identical cells are formed

Chromosomes line up along the middle of the cell.

DNA and sub-cellular structures are copied.

Which statements describe what happens during the second stage of the cell cycle. 

Two genetically identical daughter cells are produced.

After cell growth the cell has twice the amount of DNA.

Daughter cells have different chromosomes to the parent cell.

Chromosomes are pulled to each end of the cell and then line up in the middle.

Which statements about the cell cycle are true?

In an animal cell which sub-cellular structure holds the genetic material?

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 it

Cell division that produces genetically identical cells is called?

Arrange these in ascending size order from smallest to largest. 

Why does mitosis take place in multicellular organisms?
