Cell Respiration and Photosynthesis

What is needed for photosynthesis to occur?

• water

• sunlight

• carbon dioxide

• sugar

• all of the above

Which of the following describes the process of photosynthesis?

• a process where the cell used sugar and oxygen to create energy for cellular processes.

• a process where oxygen is removed from atmosphere to create Co2.

• a process that converts solar energy into chemical energy stored in the chemical bonds of sugars.

• a process that uses carbon dioxide to make ATP energy.

What impact would you expect deforestation to have on the carbon cycle?

• If there are fewer plants, less CO2 will remain in the atmosphere

• The increased use of fossil fuels would cause CO2 levels to remain the same

• If there are fewer plants, more CO2 will remain in the atmosphere.

• More human living in an area would cause CO2 levels to decrease in atmosphere

Where does photosynthesis take place?

• vacuole

• chloroplast

• nucleus

• mitochondrion

What are the two key components of carbon cycle?

Justify the reason stomata are important part of the plant.

• they allow for gas exchange of oxygen and water

• they allow for gas exchange of oxygen and carbon dioxide
