Photosynthesis & Cellular Respiration Notes

The ________________________ of Photosynthesis is a ________________ _______________.

_________ __________________ chemical reaction of our planet!!

Photosynthesis Equation:

Light Energy

_________________ + ____________________ ___________________ + ___________________

Actual Equation:

___________ molecules of Carbon Dioxide react with ______ molecules of water to form ____ molecule of glucose

(sugar) and _______molecules of oxygen.

Description of Photosynthesis:

1. The process of changing ______________ energy to _______________ energy.

2. Energy is stored as a ________________.

3. Occurs in ____________ and some algae.

4. Plants need light energy, _________________, and water.

5. Tapes place in the __________________ using chlorophyll __________________________________.

What Happens During Photosynthesis?

1. Carbon Dioxide enters the leaf through holes called _________________________.

2. Carbon Dioxide combines with stored energy in the chloroplasts through a chemical reaction to make sugar.

3. The sugar moved through tubes in the leaf to the _____________, stems, and ___________ of the

plants.

4. Some of the sugar is used right away by the plant; some of it is stored as starch, and some is built into ________

_____________

**Oxygen is released during this reaction**

Why is Photosynthesis so Important?

1. We _________________ make our own food.

2. Plants are the ____________ step in the food chain

3. The ___________________ released is necessary for __________ living things.

What is Cellular Respiration? _____________________________________________________________________________________________

_____________________________________________________________________________________________.

Description of Cellular Respiration:

1. The _______________ of sugar molecules to release energy.

2. Takes place in all living things.

3. Step by step process

Cellular Respiration Equation:

________________________ + Oxygen ____________________ + Water

How is Cellular Respiration & Photosynthesis Related?

1. Photosynthesis and cellular respiration are two processes that depend on each other. Each process makes what the other one needs. 2. Photosynthesis uses water and carbon dioxide, and it makes glucose and oxygen. Cellular respiration uses glucose and oxygen, and it makes water and carbon dioxide. 3. Photosynthesis builds the sugars that cellular respiration breaks down. In breaking down the sugars, cellular respiration makes the smaller molecules that photosynthesis uses to build more sugars.
