Set up today’s page for notes… Page: 68 Date: Title: Photosynthesis & Cellular Respiration Essential Question: How are photosynthesis and cellular respiration related? Yes, Cornell notes!!

How is energy transformed in living things?

Energy: the ability to do work

Most energy comes from the sun in the form of light.

Unused energy leaves the Earth in the form of heat.

PHOTOSYNTHESIS: the process by which some plants produce food using sunlight

For photosynthesis, plants need three REACTANTS: 1. sunlight (energy) 2. water 3. carbon dioxide

After photosynthesis, the plant has two PRODUCTS: 1.glucose (used as food) 2.oxygen (released through the leaves)

SUNLIGHT The equation of photosynthesis is: 6 CO H 2 O + sunlight  C 6 H O 2 carbon dioxide + water + energy  glucose + oxygen Now…draw the equation in pictures!

Chloroplasts: organelle where photosynthesis occurs Chlorophyll: inside chloroplasts; makes plants green

How do animals get energy?

Cellular respiration: the process that releases energy (ATP) by breaking down glucose

occurs in the mitochondria of plant and animal cells makes 36 ATP molecules Mitochondria

(Adenosine triphosphate) ATP: how cells store and release energy – stored in the bonds between elements

Talk to your partner: If humans do not make our own food by photosynthesis, how do we get the nutrients to perform cellular respiration?

The equation for cellular respiration is: 6 O 2 + C 6 H 12 O 6  6 CO H 2 O + Energy oxygen + glucose  carbon dioxide + water + ATP Now…draw the equation in pictures!
