Below is everything the examiners think you know, if you're not sure of something click on the link to watch my YouTube video explanation. For a copy of these you can print off, get the FREE revision guide I wrote for you.


 • I can recall the word and symbol equation for photosynthesis

 • I can describe the transfer of energy in photosynthesis

 • I can recall that photosynthesis is endothermic

 • I can explain how different factors affect the rate of photosynthesis. Including temperature, light intensity, carbon dioxide concentration and the amount of chlorophyll

 • I can explain that more than one factor may be limiting the rate of photosynthesis Higher tier only

 • I can explain the graphs showing how a limiting factor will affect the rate of photosynthesis Higher tier only

 • I can describe what the glucose produced in photosynthesis can be used for

 • I can relate the structure of plant cells (including root hair cells) to their function, including adaptations.

 • I can recall the different types and location of plant tissues. Epidermal tissue, palisade mesophyll, spongy mesophyll, xylem, phloem and meristem

 • I can describe the structure and function of the xylem and phloem

 • I can define the term transpiration

 • I can describe how to measure transpiration

 • I can explain the effect that temperature/humidity/air movement/light has on transpiration
