Explanation:

To prove the necessity of carbon dioxide in photosynthesis following steps need to do

Insert a part of the leaf of a destarched plant into a conical flask containing potassium hydroxide.

<u>Potassium hydroxide solution</u> absorbs the carbon dioxide gas from the air present in the glass bottle.

Leave the plant sunlight.

After few hours, perform a starch test to this and another leaf of the same plant.

<u>Observation</u>-

Leaf exposed to the atmosphere are bluish black.

Leaf exposed to KOH does not change to blue-black colour

<u>Result</u>- Starch is present in the green part of the leaf.

<u>Conclusion</u>- Presence of starch proves that chlorophyll is necessary for photosynthesis as it traps sunlight.

Above 380C and below OoC the rate of photosynthesis decreases. Propose a hypothesis to explain why this occurs.
Effectus [21]

<u>Answer:</u>

<em>Enzyme activity decrease at these temperatures. </em>

<u>Explanation:</u>

Photosynthesis is facilitated by the action of various enzymes and involves light and dark reactions.  In <em>light reactions chlorophyll absorbs sunlight and creates ATP AND NADPH</em>. In dark reactions carbon is fixed using the <em>ATP and NADPH. </em>

The efficiency of all these activities depends on the activity of enzymes which depends on the temperature. The optimum temperature range where the enzyme activity is optimal is about <em>10°c - 20°c</em>. At low temperatures and high temperatures enzyme activity is less efficient.

<em>At a temperature above 38°c and below  0°c enzyme activity decreases. </em>
