Lesson Title: Today we are learning about
How do we replace old and damaged cells?

Remember to check for PROGRESS
Focus on Knowledge, Skills and Understanding

Success Criteria:	You will show your learning by...
The nucleus of a cell contains chromosomes made of DNA molecules. Each chromosome carries a large number of genes. In body cells the chromosomes are normally found in pairs. Cells divide in a series of stages called the cell cycle. Students should be able to describe the stages of the cell cycle, including mitosis. During the cell cycle the genetic material is doubled and then divided into two identical cells. Before a cell can divide it needs to grow and increase the number of sub-cellular structures such as ribosomes and mitochondria. The DNA replicates to form two copies of each chromosome. In mitosis one set of chromosomes is pulled to each end of the cell and the nucleus divides. Finally the cytoplasm and cell membranes divide to form two identical cells. Students need to understand the three overall stages of the cell cycle but do not need to know the different phases of the mitosis stage. Cell division by mitosis is important in the growth and development of multicellular organisms. Students should be able to recognise and describe situations in given contexts where mitosis is occurring.

Keywords:

Multicellular: Organism made of more than one cell. (1)
Mitosis: Cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus. (1)
Cell Cycle: Growth and reproduction of cells consisting of different stages including interphase and mitosis. (1)
Chromosome: Long section of DNA containing many genes. (1)

AFL/Key Questions:

What is contained in the cell nucleus?
The nucleus of a cell contains chromosomes made of DNA molecules
What is a chromosome made up of?
Each chromosome carries a large number of genes
How are chromosomes normally found in body cells?
In body cells the chromosomes are normally found in pairs.
What is a cell cycle?
Where cells divide in a series of stages
What happens during the cell cycle?
During the cell cycle the genetic material is doubled and then divided into two identical cells.
What must happen before a cell divides?
Before a cell can divide it needs to grow and increase the number of sub-cellular structures such as ribosomes and mitochondria. The DNA replicates to form two copies of each chromosome.
in mitosis what happens after DNA has been replicated?
In mitosis one set of chromosomes is pulled to each end of the cell and the nucleus divides.
In mitosis how many cells are produced and how could you describe them?
Two - identical daughter cells
What are the three main stages of a cell cycle during mitosis?
1. Replication of DNA 2. DNA divides 3. Two cells formed
Why is cell division by mitosis important in multicellular organisms?
For growth and development
A human cell has 46 pairs of choromsomes what stage of mitosis is in it?
First stage - replication of DNA (Prophase)
