B3 Diagnostic Checklist
What do you already know?
RAG rate yourself according to your answers from the diagnostic quiz.
understand the similarities and differences between plant and animal cells
know that some organisms make their own food using photosynthesis
know that photosynthesis in plant cells occurs in the chloroplasts
know the reactants in, and products of, photosynthesis, and be able to write a word summary
know that photosynthesis requires light
be familiar with the adaptations of leaves for photosynthesis, and the role of stomata in gas exchange
know that water and minerals enter a plant through the roots
know that molecules of a solute move through solvent, and through cell membranes, by diffusion
know that animals obtain their food from plants (and other animals that ate plants)
understand the difference between carnivores, herbivores and omnivores, and between producers and consumers
know that individuals of the same type living in the same place make up a population, and that all the interacting populations in an
ecosystem make up the community
understand the use of food chains and food webs as models of the feeding relationships within a community
appreciate the interdependence of organisms in a community, including food webs, the breakdown and cycling of substances, and
animals as pollinators
know that changes in an ecosystem can affect the survival of individuals and populations.
