Answer 1

Answer:

part of leaf that will turn blue black is that which is not covered with black paper

Answer 2

mohls half leaf experiment.

explanation :

in the experiment carbon dioxide is essential to photosynthesis in order to prove this we need to select destarched potted plant and Pet bottle, potassium hydroxide crystals , Grease, and Rubber cork . we need to to select a healthy life and insert the half of the leaf into a pet bottle and close the bottle with the help of rubber cork and apply the Vaseline on the gapps in order to to prevent entry of carbon dioxide . we need potassium crystals it have the capacity to observe the carbon action which is correct inside the bottle and keep the entire set up under the sunlight for 5 to 6 hours after remove the bottle from the plant and take the leaf away from the plant and pour some iodine solution it it says that the presence of starch when we put iodine solution on the leaf the leaf which is outside the bottle is changes into the blue black in colour because it participates in photosynthesis and produces starch the leaf which is present inside the bottle it doesn't turns into black in colour because it doesn't conduct any photosynthesis .

conclusion : by doing this activity I conclude that photosynthesis is essential for photosynthesis .

hope it helps you!
