Test on Friday 20th November on everything you've done this year...
3.1 understand the differences between sexual and asexual reproduction
3.2 understand that fertilisation involves the fusion of a male and female gamete to produce a zygote that undergoes cell division and develops into an embryo
3.3 describe the structures of an insect-pollinated and a wind-pollinated flower and explain how each is adapted for pollination
3.4 understand that the growth of the pollen tube followed by fertilisation leads to seed and fruit formation
3.5 understand the conditions needed for seed germination
3.6 understand how germinating seeds utilise food reserves until the seedling can carry out photosynthesis
3.7 understand that plants can reproduce asexually by natural methods (illustrated by runners) and by artificial methods (illustrated by cuttings)
2.49 understand why simple, unicellular organisms can rely on diffusion for movement of substances in and out of the cell
2.50 understand the need for a transport system in multicellular organisms
2.51 describe the role of phloem in transporting sucrose and amino acids between the leaves and other parts of the plant
2.52 describe the role of xylem in transporting water and mineral salts from the roots to other parts of the plant
2.53 explain how water is absorbed by root hair cells
2.54 understand that transpiration is the evaporation of water from the surface of a plant
2.55 explain how the rate of transpiration is affected by changes in humidity, wind speed, temperature and light intensity
2.56 describe experiments to investigate the role of environmental factors in determining the rate of transpiration from a leafy shoot
4.11 understand the biological consequences of pollution of air by sulfur dioxide and by carbon monoxide
4.12 understand that water vapour, carbon dioxide, nitrous oxide, methane and CFCs are greenhouse gases
4.13 understand how human activities contribute to greenhouse gases
4.14 understand how an increase in greenhouse gases results in an enhanced greenhouse effect and that this may lead to global warming and its consequences
