1. Transport of water and mineral salts

10. Summary

11. Photosynthesis

12. Adaptations of the leaf to photosynthesis Refer to pg.114 textbook click me! click me! click me ! click me! click me! click me! Any broad and flattened region of a plant or alga, which allows for increased photosynthetic surface area

13. Absorption spectrum

17. Visible light is a part of a larger spectrum of radiation called the electromagnetic spectrum Electromagnetic spectrum

18. We perceive the colours of objects because… The wavelengths of light is either absorbed or reflected We see only the reflected wavelengths of light

22. Absorption and action spectrum Action spectrum is an indicator of which wavelength of light can be used by a plant to allow photosynthesis Absorption spectrum is the spectrum used to measure absorption of the various wavelengths of light Pg.121 textbook

23. Absorption and action spectrum

24. Limiting factors Definition: Any factor that directly affects a process if its quantity is changed 1. Concentration of CO 2 2. Light intensity 3. Temperature Rate of photosynthesis is affected by external factors such as: sunlight chlorophyll Carbon dioxide + water -> glucose + oxygen + water vapour

25. Limiting factors Effects of various factors on the rate of photosynthesis
