Year 8 Recap

A variable is…

• Anything that can be changed in an experiment
• Any data that has a numerical value, drawn as a scatter graph
• Data that can be grouped, such as labels or brands, drawn as a bar graph
• The variables that are kept the same in an experiment
• The variable that is measured in an experiment

An independent variable is…

• The variable that is changed in an experiment
• Anything that can be changed in an experiment
• Any data that has a numerical value, drawn as a scatter graph
• Data that can be grouped, such as labels or brands, drawn as a bar graph
• The variables that are kept the same in an experiment

The Cell Membrane is ..

• ..the layer around a cell that controls what substances enter and leave the cell.
• ..the part of a plant that contains cell sap and nutrients. It helps to keep the cell firm.
• ..a cell that carries out a particular function.
• ..a chemical reaction where food (glucose) and oxygen are changed into water and carbon dioxide. When this happens energy is released to keep the organism alive.
• ..a living thing like a plant, animal or bacteria etc.

The cell wall is..

• ..found in plant cells. A tough outer layer made of cellulose that surrounds the cell and gives it support.
• ..the layer around a cell that controls what substances enter and leave the cell.
• ..the part of a plant that contains cell sap and nutrients. It helps to keep the cell firm.
• ..a cell that carries out a particular function.
• ..a chemical reaction where food (glucose) and oxygen are changed into water and carbon dioxide. When this happens energy is released to keep the organism alive.

Cells are…

• ..building block that all living things are made up of.
• ..found in plant cells. A tough outer layer made of cellulose that surrounds the cell and gives it support.
• ..the layer around a cell that controls what substances enter and leave the cell.
• ..the part of a plant that contains cell sap and nutrients. It helps to keep the cell firm.
• ..a cell that carries out a particular function.

The chloraplasts are..

• ..found in plant cells and contain a chemical called chlorophyll. They trap light to help the plant photosynthesise.
• ..building block that all living things are made up of.
• ..found in plant cells. A tough outer layer made of cellulose that surrounds the cell and gives it support.
• ..the layer around a cell that controls what substances enter and leave the cell.
• ..the part of a plant that contains cell sap and nutrients. It helps to keep the cell firm.
