question 2 (3 points)
(02.06 mc)
the table below shows the role of different substances during photosynthesis.

substance	role during photosynthesis
water	combines with carbon dioxide to form glucose
chlorophyll	combines with water to form oxygen

which of the following statements would correct one of the roles listed in the table?
o a water combines with oxygen to form glucose.
o b water is formed with sugar during photosynthesis.
o c sunlight is not transformed into other forms of energy.
o d chlorophyll absorbs the light needed for photosynthesis.
question 3 (3 points)
(02.06 mc)
the chemical equation shown represents photosynthesis.
carbon dioxide + a+ light -x→ b + oxygen
x represents a substance in a plant involved in photosynthesis. what is its role?
o a it stores chemical energy for plants and animals.
o b it traps light energy and converts it into chemical energy.
o c it combines with carbon dioxide and light to form glucose.
o d it combines with carbon dioxide and light to form hydrogen.
question 4 (3 points)
(02.06 lc)
which of the following is a product of cellular respiration?
o a carbon dioxide
o b glucose
o c mitochondria
o d oxygen

Explanation:

• Question 2: Chlorophyll's main role in photosynthesis is to absorb light energy. The incorrect statement in the table is about chlorophyll combining with water to form oxygen. The correct statement is that chlorophyll absorbs the light needed for photosynthesis.
• Question 3: In the photosynthesis equation, the substance represented by X is chlorophyll. Chlorophyll traps light energy and converts it into chemical energy.
• Question 4: Cellular respiration uses glucose and oxygen to produce carbon - dioxide, water, and energy. Carbon dioxide is a product of cellular respiration.

Answer:

• Question 2: d. Chlorophyll absorbs the light needed for photosynthesis.
• Question 3: b. It traps light energy and converts it into chemical energy.
• Question 4: a. Carbon dioxide
