- The rate of photosynthesis
- The temperature has to be just right
- Usually if the temperature is the limiting factor it's because it's too low
- This is because the enzymes needed for photosynthesis work more slowly at low temperature
- But if the plant gets too hot, photosynthesis won't happen at all
- This is because the enzymes are damaged if the temperature's too high (over 45 c )
- Usually if the temperature is the limiting factor it's because it's too low
- How plants use glucose
- MAKING PROTEINS
- Plants absorb nitrate ions from soil
- Glucose is joined with nitrate ions to make amino acids
- The amino acids are then made into proteins
- MAKING CELL WALLS
- Glucose is made into cellulose
- Cellulose is used to make strong cell walls
- FOR RESPIRATION
- Plants make glucose in their leaves
- They then use some of the glucose for respiration
- STORED IN SEEDS
- Glucose is turned into fats and oils for storing in seeds. e.g. we get margarine from sunflower seeds. Seeds also store starch
- STORED IN STARCH
- Glucose is turned into starch and stored in roots, stems and leaves
- Starch is insoluble- it doesn't dissolve. This makes starch much better for storing than glucose
