Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the best prediction of the relationship between light distance and the rate of photosynthesis?
A
There is no relationship between light distance and the rate of photosynthesis.
B
Distance between the light and the algae does not affect the rate of photosynthesis
C
The more distance between the light and the algae the greater the rate of photosynthesis.
D
The less distance between the light and the algae the greater the rate of photosynthesis.
Explanation: 

Detailed explanation-1: -The less distance between the light and the algae the greater the rate of photosynthesis.

Detailed explanation-2: -As you rise from low light intensity to higher light intensity, the rate of photosynthesis will increase because there is more light available to drive the reactions of photosynthesis.

Detailed explanation-3: -As the light levels are increased there is an increase in oxygen (bubble) production from photosynthesis of the plant.

Detailed explanation-4: -Choice (c) is correct. The products of cellular respiration are carbon dioxide and water, which are the raw materials for photosynthesis.

Detailed explanation-5: -Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
