| 1. Glucose is used immediately. | - cellular respiration ⇒ provide energy for cellular activities. - to form cellulose of cell walls |
| 2. Important: Photosynthesis stops ⇒ starch is converted back into glucose | a) in daylight ⇒ rate of photosynthesis → so great that glucose is formed faster than it can be removed. ⇒ excess glucose is converted to starch and stored. b) in darkness ⇒ photosynthesis stops. ⇒ starch is converted back into glucose. |
| 3. Glucose is converted to sucrose | - Transported to other parts of plant or to storage organs (seeds, stem tubers, root tubers) ⇒ via phloem. - converted to other forms of storage compounds at storage organs ⇒ depending on plant. - May be converted back into glucose for respiration - Component of nectar in flowers ⇒ attract insects for pollination Pollination |
| 4. Glucose is converted to amino acids in leaves | Excess is transported to other parts of the plant. - for synthesis of new protoplasm - for storage as proteins Used to form proteins ⇒ used for synthesis of new protoplasm in leaves\ |
| 5. Glucose forms fats. | - for storage - used in cellular respiration - for synthesis of new protoplasm. |
