Key Stage 3

Meaning

The nucleus can be seen in the centre of this cell.

The nucleus is the part of the cell that contains DNA which provides instructions for how the cell should behave.

Singular Noun: Nucleus Plural Noun: Nuclei

Function

The nucleus controls the cell.

About the Nucleus

The nucleus contains the genetic material of a cell.
Nuclei are found in plant cells and animal cells but not in Bacteria.

Examples

OnionCells.png
MuscleCells.png
The nuclei of these cells can be seen stained blue. The nuclei of these cells is a darker pink than the rest of the cells.
SpermCellClipart.png
PalisadeCellClipart.png
The nucleus in this sperm cell is very large compared to the cell. A picture of a palisade cell showing several parts including the nucleus.

Key Stage 4

Meaning

A nucleus is a membrane bound organelle found in eukaryotic cells containing the DNA.

Function

The nucleus contains DNA which controls the actions of the cell and provides the information to make copies of the cell.

About the Nucleus

The nucleus contains genes which determine which proteins are synthesised in the cell.
During mitosis before the cell divides the membrane of the nucleus dissolves to release two sets of chromosomes which then form two identical nuclei.
Nuclei are found in animal cells, plant cells, fungal cells and protists but are not found in bacteria or archaea.

Examples

OnionCells.png
MuscleCells.png
The nuclei of these cells can be seen stained blue. The nuclei of these cells is a darker pink than the rest of the cells.
SpermCellClipart.png
PalisadeCellClipart.png
The nucleus in this sperm cell is very large compared to the cell. A picture of a palisade cell showing several parts including the nucleus.
