Question 8 :
Are the following statement true or false? Give reason in support of your answer. The rate of photosynthesis continues to rise as long as the intensity of light rises.

Question 11 :
Are the following statement true or false? Give reason in support of your answer. If you immerse a leaf intact on the plant in ice cold water, it will continue to photosynthesise in bright sunshine.
Question 12 :
A variegated leaf (one that has green as well as white patches) will Photosynthesize only in the green areas.
Question 13 :
<strong>Mention, if the following statement is True or False. If false rewrite the wrong statement in its correct form:</strong> The plasma membrane permits the passage of all solutes and water.
Question 14 :
Identify the false statements and rewrite them correctly by changing the first or last word only. Photosynthesis results in loss of dry weight of the plants.
Question 15 :
Identify the false statements and rewrite them correctly by changing the first or last word only. Starch produced in a leaf remains stored in it for 2-3 weeks before it is used by other parts of the plant.
Question 19 :
<strong>Mention, if the following statement is True or False. If false rewrite the wrong statement in its correct form:</strong> PhotoLysis is the reaction which means the breaking up of water molecules.
Question 21 :
<strong>Mention, if the following statement is True or False. If false rewrite the wrong statement in its correct form:</strong> Too much light destroys chlorophyll.
Question 22 :
The unit of light absorbed by the chlorophyll during photosynthesis is the proton.

The following statement is about photosynthesis in a green plant. Write whether it is True or False. A variegated leaf (one that has white as well as green patches) will only photosynthesize in the green areas.
Question 24 :
Leaves are broad and flat to increase the surface area for photosynthesis.
