- 1. Multiple ChoiceThere are more chloroplasts in the palisade mesophyll cells than in spongy mesophyll cells.TrueFalse
- 2. Multiple ChoiceThe lamina is broad to increase surface area for maximum absorption of light energy.TrueFalse
- 3. Multiple ChoiceThe thin film of moisture on the surfaces of mesophyll cells allow glucose to dissolve in it to aid faster rate of diffusion of glucose.TrueFalse
- 4. Multiple ChoiceStomata open to allow gas exchange to take place during photosynthesis.TrueFalse
- 5. Multiple ChoiceThe equation for photosynthesis isoxygen + water --> glucose + carbon dioxideoxygen + glucose --> carbon dioxide + watercarbon dioxide + water --> glucose + oxygencarbon dioxide + glucose --> oxygen + water
- 6. Multiple ChoiceChlorophyll traps light energy and converts it to chemical energy during photosynthesis.TrueFalse
- 7. Multiple Choice
Name the limiting factor at X.Light intensityTemperatureCarbon dioxide concentrationWater - 8. Multiple ChoiceWhy does temperature have an effect on the rate of photosynthesis?Higher temperature allows carbon dioxide to diffuse into the leaves faster.Higher temperature allows water to be transported to the leaves faster.Higher temperature allows the stomata to open wider.Higher temperature allows the enzymes to function better.
- 9. Multiple ChoiceExcess glucose is converted to glycogen for storage in plants.TrueFalse
- 10. Multiple ChoiceGlucose is converted to starch for transport in plants.TrueFalse
- 11. Multiple ChoiceXylem is a long, hollow tube without any protoplasm to provide mechanical support to the plant.TrueFalse
- 12. Multiple ChoicePhloem is living due to the presence of companion cells.TrueFalse
- 13. Multiple ChoiceTranspiration is the loss of water through the stomata of the leaves.TrueFalse
- 14. Multiple ChoiceTranslocation is the transport of manufactured food by the phloem.TrueFalse
- 15. Multiple ChoiceIncreasing humidity decreases the rate of transpiration as the water potential of the surrounding is higher than the sub-stomatal spaces.TrueFalse
