    The idea

    This statement limits the organisms you need to know for this topic to those named in the specification. You should be able to describe reproduction in malarial parasites (which reproduce asexually in the human host, but sexually in the mosquito), fungi (which reproduce asexually by spores but also reproduce sexually to give variation), and plants (which produce seeds sexually, but also reproduce asexually by runners such as strawberry plants, or bulb division such as daffodils). You are not required to recall examples of reproduction in other organisms unless the question supplies that information. However, if a question gives you information about an unfamiliar organism, you should be able to apply your understanding of asexual and sexual reproduction to explain advantages and disadvantages for that organism.

    What earns the marks

    • The specification restricts required examples of reproduction to those named: malarial parasites, fungi, and specific plants (strawberries and daffodils).
    • You should know that malarial parasites reproduce asexually in humans and sexually in mosquitoes.
    • You should know that many fungi reproduce asexually by spores but also reproduce sexually to give variation.
    • You should know asexual reproduction in strawberry plants by runners and in daffodils by bulb division.
    • You should be able to apply the principles of asexual and sexual reproduction to an unfamiliar organism when given appropriate information.

    Common mistakes and how to put them right

    • Stating that fungi only reproduce asexually.

      Put it right: They can reproduce sexually to introduce variation.

    • Assuming that unfamiliar organisms cannot be assessed.

      Put it right: Questions may give information and ask you to apply your understanding.

    • Confusing the named plant examples, for example saying daffodils reproduce by runners instead of bulbs.

    Exam tips

    • Use the examples named in the specification, such as malarial parasites, fungi, strawberry runners, and daffodil bulb division, when asked for named examples.
    • If a question introduces an unfamiliar organism, read the information carefully and apply the same principles of asexual or sexual reproduction.

    This statement limits the organisms you need to know for this topic to those named in the specification. You should be able to describe reproduction in malarial parasites (which reproduce asexually in the human host, but sexually in the mosquito), fungi (which reproduce asexually by spores but also reproduce sexually to give variation), and plants (which produce seeds sexually, but also reproduce asexually by runners such as strawberry plants, or bulb division such as daffodils). You are not required to recall examples of reproduction in other organisms unless the question supplies that information. However, if a question gives you information about an unfamiliar organism, you should be able to apply your understanding of asexual and sexual reproduction to explain advantages and disadvantages for that organism. A strong answer earns marks for these points. The specification restricts required examples of reproduction to those named: malarial parasites, fungi, and specific plants (strawberries and daffodils). You should know that malarial parasites reproduce asexually in humans and sexually in mosquitoes. You should know that many fungi reproduce asexually by spores but also reproduce sexually to give variation. You should know asexual reproduction in strawberry plants by runners and in daffodils by bulb division. Exam tip: Use the examples named in the specification, such as malarial parasites, fungi, strawberry runners, and daffodil bulb division, when asked for named examples.
