GCSE Science learning topics and material for students in Year 7 to Year 11.
The cell's structure is related to the job it does, so cell structures vary from one another. When cells express specific genes that characterise a certain type of cell we say that a cell has become differentiated.
Cells are the basic unit of life. Cells are the basic building blocks that make up all living organisms and they come together in many shapes and sizes.
Chromosomes carry genetic information in a molecule called DNA. A type of cell division called mitosis ensures process happens.
Health and diet science is the study of how the food we eat affects our health. It includes the study of nutrients, how they are absorbed and used by the body.
There is no doubt that osmosis is an important process for life. It is how cells get the water they need to carry out chemical reactions.
The mitosis process produces two identical diploid cells for the purpose of growth and repair after cell division.
Enzymes are proteins that catalyse biochemical reactions. This means that they increase the speed of these reactions without being consumed themselves.
The osmosis process involves the movement of water molecules across a partially permeable membrane from a region of high water concentration to a region of low concentration.
Exercise is an important part of a healthy lifestyle. It helps to maintain a healthy weight, boosts energy levels, and reduces the risk of diseases such as heart disease.
