Cell level systems

  • Cell structures - OCR Gateway

    Organisms are made of cells. Most organisms are multicellular and have cells that are specialised to do a particular job. Microscopes produce magnified images of cells so we can study them in detail.

  • What happens in cells (and what do cells need)? - OCR Gateway

    The genetic code of all life on Earth is made from DNA. Proteins like enzymes and hormones are made during protein synthesis. Enzymes are biological catalysts which speed up chemical reactions.

  • Respiration - OCR Gateway

    Respiration releases energy from glucose in the form of ATP. This occurs in all living cells. Aerobic respiration (with oxygen) releases more energy than anaerobic respiration (without oxygen). In this study guide you will learn about aerobic and anaerobic respiration, the aerobic respiration word equation and metabolism in plants and animals.

  • Photosynthesis - OCR Gateway

    Plants make food using photosynthesis. This food is important for the plants themselves and for organisms that feed on plants. Getting optimum rates of photosynthesis produces maximum plant yields.

  • Sample exam questions - cell level systems - OCR Gateway

    Understanding how to approach exam questions helps to boost exam performance. Question types will include multiple choice, structured, mathematical and practical questions.

Scaling up

  • Supplying the cell - OCR Gateway

    For an organism to function, substances must move into and out of cells. Three processes contribute to this movement - diffusion, osmosis and active transport.

  • Mitosis and cell specialisation - OCR Gateway

    Mitosis is cell division which produces two identical diploid cells for growth and repair. Differentiation occurs when cells become specialised. Stem cells can develop into different cell types.

  • The challenges of size in animals - OCR Gateway

    Larger animals have a lower surface area to volume ratio. This means they need transport systems like our circulatory system and exchange surfaces like our lungs or fish gills.

  • The challenges of size in plants - OCR Gateway

    During transpiration plants move water from the roots to their leaves for photosynthesis in xylem vessels. Glucose made in photosynthesis is then moved to all cells in phloem vessels for respiration.

  • Sample exam questions - scaling up - OCR Gateway

    Understanding how to approach exam questions helps to boost exam performance. Question types will include multiple choice, structured, mathematical and practical questions.

    Scientific investigations have several stages - planning, collecting data, analysing data and evaluation. It is important to understand how to carry out each stage of the investigation.
