Understand that all living things share the characteristics described in MRS C GREN (F)
Know that living things are classified into groups based on similarities and features
Know that organisms are classified into groups
Know The main groups that living things are classified into; Bacteria (Monera), Protists, Animals, Plants, Fungi
Be able to use a key to identify organisms
Understand that different types of living organisms have common ancestors from which they evolved through the process of Natural Selection. (extension)
Know that all living organisms are made up of cells
Know the structure of a typical animal cell and a typical plant cell (cell membrane, cytoplasm, nucleus, cell wall, vacuole, chloroplast only)
Know how plant and animal cells are similar and different
Know the functions of the parts of animal and plant cells
Know the significance of the differences in structure between animal and plant cells
Know the roles of and links between organisms in a community (habitat, niche, food webs)
Know that an ecosystem is the habitat and the community considered together
Know the role of producers, consumers and decomposers in food chains and webs.
Understand that energy losses occur along a food chain

Know that digestion breaks large molecules of food into small ones, which can then pass through the wall of the gut into the blood
Know the internal structure of a human tooth and how the different types of human teeth are used when eating
Know that the gut is a coiled tube and is the site of digestion and absorption
Be able to identify the main structure of the digestive system and its associated organs (mouth, oesophagus, stomach, small and large intestine, rectum, anus,
pancreas and liver)
Know that the small intestine is the site of absorption of the products of
digestion.
The food we eat is divided into four main groups
We use tests to determine which type of food is present

I need to learn this
I know this
Know the structure and functions of parts of the plant and processes within (roots: support, osmosis, stem: transport, support, leaves: photosynthesis, transpiration, flowers: reproduction)
Know the significance of photosynthesis in making food
Know that photosynthesis transfers energy from sunlight into energy in chemicals such as glucose and starch
Know how to perform starch tests on leaves.
Know that plants take up water through root hairs
Know that xylem transports water and that phloem transports the products of photosynthesis
Know that osmosis is the diffusion of water molecules through a partially permeable membrane
Describe the adaptations of leaves for photosynthesis
Know the process of transpiration
Know how the structure of a leaf enables photosynthesis to occur effectively.
Know the parts of the flower and the role of the flower in pollination, seed production and dispersal
Know the reproductive parts of an insect-pollinated flower and understand their functioning
Know the differences in structure between insect-and wind-pollinated flowers
Understand the formation of seed and fruit from ovule and ovary
Know the importance of seed dispersal and describe examples of animal- and wind-dispersed seeds or fruits
Know the conditions needed for germination of seeds
Know the structure of a bean seed (testa, micropyle, cotyledons, plumule and radicle only).
Know the importance of plants as producers
Know that energy enters an ecosystem in sunlight, which is transferred to energy in plants by photosynthesis and that this energy is then passed along food chains
