Multicellular organisms grow by increasing the number of cells they have; this involves cell division.

An organism that consists of only one cell.

The process by which cells replicate to produce two genetically identical cells.

Growth in multicellular organisms

Combined science

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

It controls what enters and exits the cell.

Which statements are true for the nucleus?

Which two processes do animal and plants usually use cell division for?

Two cells are produced with half the DNA.

Two genetically identical cells are produced.

Four cells are produced from the original cell.

Which of these statements are true for cell division in animals?

What is the word used to describe organisms increasing in size by adding more cells?

Bacteria use cell division for growth and repair.

Match each term to the correct defintion.

If in the same organism, order these structures from smallest to largest. 

Which sub-cellular structure contains the DNA in animal cells?

Which of these organisms is multicellular?
