plants need ______________________ too.

So plants do Photosynthesis to make their food, then they do cellular respiration to get energy from their food! Does that mean plants are cannibals?!!

By:http://skyways.lib.ks.us/towns/ElkCity/2007flood.html

Plants do

____________

but

photosynthesis

oxygen for cellular respiration

Factors Affecting Cellular Respiration

1. Temperature – usually the rate of cellular respiration increases as temperature increases

• This is why you sweat more if its hot when you work out or dance or whatever you do to sweat.

• You are burning Food for energy, doing more cellular respiration

Factors that affect Cellular Respiration

1. Glucose and Oxygen – The more reactants the cell has, the more energy it can produce

What happens when you don’t eat enough?

No Energy!!!!Weak!!!!

Check for Understanding

1. Write the equation for Cellular Respiration.

2. What is the name of the molecule the cell uses to store energy taken from sugar and other food?

3. Besides sugar what does an organism need in order to do cellular respiration?

4. What is the name of the organelle where cellular respiration takes place?

5. If I am not feeling energetic what can I do to increase my cellular respiration?
