The reaction 6CO2 +6H2O + energy --> C6H12O6 + 6O2 is a reaction you have probably seen before.

The reactant 6CO2 enters the plant ___ (from the atmosphere, from the soil, from sugar, from sunlight).

The reactant energy enters the plant through ___ (from the atmosphere, from the soil, from sugar, from sunlight)

The product C6H12O6 is ___ (metabolized by the plant in its mitochondria, converted into ATP) and is created through the (oxidation, reduction) of CO2.

The product 6O2 is considered a (reactant for oxygenic photosynthesis, waste product of oxygenic photosynthesis, waste product of anoxgenic photosynethesis, a reactant for anoxygenic photosynthesis)

Explanation:

1. From the atmosphere. The CO2 found in the atmosphere including ones expelled by animals during respiration is used in photosynthesis

2. From sunlight. During photosynthesis, plants utilize energy from the sun also known as solar energy converting it into chemical energy

3. The product which is glucose is metabolized in the mitochondria

4. The reduction of CO2 with it acting as an electron acceptor

5. Oxygen is a waste product of oxygenic photosynthesis wherein with oxidation of water, oxygen is produced as a byproduct

a. From the atmosphere

b. from sugar

c. from sunlight.

d. Oxygenic photosynthesis

Explanation:

a) Co2 enters into plant cell from the atmosphere through the stomata and react with water. During photosynthesis light hits the center of leave causing it to vibrate and leading to the splitting of water molecule. The oxygen is been released into the atmosphere and the Hydrogen together with Co2 forms the sugar.

b)Light energy is from sunlight. During the day when there is sun plant absorbs light from the sun to use in producing there food. This energy is what is used in the process of photosynthesis

c) C6H12O6 is converted into ATP.

In the dark cycle C6H12O6 is converted to ATP this is released back into the cell and use together with Co2 and H2O and light energy to produce C6H1206. Photosynthesis is a process that require energy and Atp is constantly used up in the process.

d) reactant for oxygenic photosynthesis- When plant stomata closes up during cold or when the weather is harsh for the plants Co2 is no longer trapped in and then leading to increase in the concentration of O2 because oxygen is released as a by product of photosynthesis. Note that when plant closes stomata photosynthesis never stops leading to a decrease in the concentration of C02 and a increase in 02 concentration as its been released as by product.

When C02 is not available in the cell the enzyme rubisco that fixes C0 start fixing 02 leading to photorespiration which is waste of time and energy.

Hence high concentration of 02 in the cell leads to oxygenic photosynthesis( photorespiration).

the correct answer is d
