Document Summary

Plants use solar energy and co2 to grow. Microbes eat plant material to gain energy. Continues to burn as heat is released. Burning wood releases co2 but co2 is consumed when a new tree grows to replace it. Photosynthesis: carbon dioxide, water, solar energy glucose and oxygen. General view of decomposition/burning ( photosynthesis in reverse ) Plant fuel and oxygen carbon dioxide, water, and solar energy. Other chemicals besides glucose burn, so this is a simplified description, but all fire releases energy that was previously stored in chemical bonds. Requires fuel (something to burn), oxygen, and a source of heat. Air is about 21% oxygen, so usually this requirement is met. When both fuel and a source of ignition are present, fire will form. It will continue to burn until all fuel has been consumed, or it is extinguished (by taking away oxygen or heat)

Select the incorrect statement regarding respiration and fermentation from the list below.

Respiration produces much more ATP than fermentation

Respiration produces acidic products, fermentation does not.

Both respiration and fermentation use organic molecules.

Respiration uses oxygen, fermentation does not.

Question 4

Select one answer.

10 points

Energy is harvested from which reaction to produce ATP?

Sugar and oxygen â carbon dioxide and water.

Question 5

Select one answer.

10 points

What is the source of energy for photosynthesis?

Light

CO2

Water

Sugar

Question 6

Select one answer.

10 points

One way to explain how cellular respiration and photosynthesis relate to each other is to say that:

Plant cells use the oxygen produced by respiration for photosynthesis.

The oxygen produced by photosynthesis, once released to the environment, is the oxygen able to be used as the electron acceptors for cellular respiration.

Cellular respiration is a series of reduction reactions while photosynthesis is a series of oxidation reactions.

The two processes are not related.

The use of oxygen by plants contributes to the greenhouse effect.

Plant leaves contain many different pigments. What is the purpose of having multiple pigments?

Capture light for photosynthesis at different wavelengths.

To absorb light that may harm the photosynthetic machinery.
