Photosynthesis & Cellular Respiration

• Reactants of one process....

• ... are the products of the other process

Energy renewal

• Energy captured from sunlight by photosynthetic organisms is used and released in the cellular respiration of living things.

• The energy that living things use, must continually be renewed through photosynthesis.

Why is Photosynthesis so important?

• We must obtain glucose from plants

• Plants are the first step in the food chain

• The oxygen released during photosynthesis is necessary for many organisms.

​What Can Limit Photosynthesis?

• ​Amount of sunlight

• ​Amount of Carbon dioxide

• ​Temperature

Cellular Respiration

• Once solar energy is converted to chemical energy by photosynthesis, it has to be changed to a form that can be used by the organism

• Cellular respiration is the process that releases energy by breaking down food molecules in the presence of oxygen

Photosynthesis vs Cellular Respiration

• Photosynthesis stores energy into glucose - Cellular Respiration releases energy from glucose

• Photosynthesis removes carbon dioxide and respiration returns it

Multiple Choice

When it is chilly and raining outside, there is no photosynthesis taking place. What is the limiting factor?

• Temperature

• Carbon Dioxide

Multiple Choice

If a plant receives more carbon dioxide, what happens to the rate of photosynthesis?

• Increases
• Decreases
• Stays the same

Multiple Choice

What happens during cellular respiration?

• Glucose is broken down, releasing energy
