photosynthesis revision
-
it happens in chloroplasts in green plant cells it contains pigments such as chlorophyll that absorb light
-
-
plants use glucose in many ways- for respiration,making cellulose for strong plant walls,making amino acids, stored as oils or fats, stored as starch
the rate is affected by light(at night),concentration of co2 (warm and bright enough) and temperature(winter)
the amount of chlorophyll in a plant can be affected by disease or environmental stress. if this happens the rate of photosynthesis is reduced because they cant absorb enough light
as the light level is raised the rate also increases up to a certain point beyond that it wont make any difference in the lab you change light intensity by moving a lamp closer or further away
too little carbon also slows the rate down and the temperature cant be too cold or too hot otherwise the enzymes will be damaged around 45 degrees
