In this practical, students use algae to look at the rate of photosynthesis
Video which demonstrates the process for cauliflower cloning - showing tissue cultures and micro-propagation.
A bried description of sexual and asexual reproduction.
A short video clip in which a plant scientist is interviewed about the various factors that affect plant growth and germination.
A short video clip describes the process of photosynthesis and shows a practical in which pondweed is seen photosynthesising at different light intensities. Key points are listed below the clip.
A description of diffusion using text, animation and rap. The defintion of diffusion is clearly stated. Examples of where diffusion occur in the human body are also given.
A description of osmosis using text, animation and a rap. The defition is clearly given.
HIgher level text and an animation of active transport (in the context of homeostasis). Linked pages include diffusion, osmosis and enzymes.
This experiment compares the rates of photosynthesis in three aquatic plants: pondweed, green algae and duckweed. Although sometimes tricky, when it works well the experiment demonstrates how effective plants can be at photosynthesis. A presentation and short video clip introduces the topic and sets the scene for the investigation. Instructions and teacher guidance for carrying out the practical work are included.
SAPS resource demonstrating how to extract oil from plants - instructions for students to complete the practical work.
A brief description of the process of phototropism in plants, which includes the role of auxins.
Several linked pages which describe plant structure including xylem, phloem and the leaf.
Several linked pages which describe photosynthesis, limiting factors and the uses of glucose.
A series of linked pages which describe tropism, the role of hormones in this process and how hormones are used in agriculture.
A description of the advantages and disadvantages (including ethical concerns) of using biofuels and detail regarding common examples.
Linked pages which describe asexual reproduction, the process of cloning, stem cells and the ethics of these techniques.
Clear summary covering the structure of the leaf, photosynthesis, limiting factors, stomata (excellent animation) and transpiration. Quite detailed in places, but good students will be able to access exam questions and test. Exam questions (section 3) is a good revision activity.
How can we measure the rates at which photosynthesis takes place?
Linked pages which explain what fertilisers are, how they are made and what eutrophication is.
