| what are the three raw materials for photosythesis? | water, carbon dioxide and light |
| what products are removed during photosynthesis? | oxygen and glucose |
| name 9 adaptations of leaves structure to photosynthesise | large SA, minimal leaf overlapping, thin, transparent cuticle, long narrow mesophyll cells, numerous stomata that open and close according to light intensity, air spaces in the lower mesophyll, network of xylem. |
| state the equation of photosynthesis | 6CO2 + 6H20 ---> C6H1206 + 6O2 |
| name and describe the three stages of photosynthesis | 1.capturing the light energy - by chloroplast pigments such as chlorophyll.
2.LDR- some light energy is absorbed. electron flow is created by the effect of light on chlorophyll, causing water to split (photolysis) into protons, electrons and oxygen. products: NADP, ATP and oxygen.
3.LIR- protons are used to create sugars and other organic molecules |
| state the shape and size of chloroplasts | disc-shaped 2-10um |
| name and describe the two regions of the chloroplast | the grana- stacks of up too 100 thylakoids, where the light dependent stage of photosynthesis occurs. pigment contained in this area. intergranular lamellae.
the stroma- fluid filled matrix where the light independent reaction occurs. |
