Chemical Equation for PhotosynthesisChemical Equation for Photosynthesis

carbon dioxide + water + glucose + oxygen

• Photo = light• Synthesis = combining parts to make something

•Photosynthesis = combining water and carbon dioxide (with the help of the sun) to make sugar!

QuestionsQuestions

1. Where do plants “get” the reactants? (3-part answer)a) Sunlight - b) Water – c) Carbon Dioxide –

2. Where in the cell does photosynthesis take place? (Hint: see Figure 1 on pg. 94)

Importance of Photosynthesis:Importance of Photosynthesis:1. FOOD•Produces food for almost all organisms.

– ChallengeChallenge – Can you think of a food that is NOT somehow traced back to a plant?

2. “FRESH” AIR•Removes carbon dioxide from, and adds oxygen to, the atmosphere.

Chemical Equation for RespirationChemical Equation for Respiration

oxygen + glucose carbon dioxide + water + ENERGY

(ATP)

Respiration = the process of breaking down glucose (in the presence of oxygen) to make ATP ENERGY!

2. Where in the cell does respiration take place? (Hint: see Figure 2 on pg. 95)

Importance of Respiration:Importance of Respiration:

• ENERGY (ATP) is like the fuel of the cell.

• ENERGY (ATP) allows cells to build and move things around to keep the organism alive.

Remember, ALL living things need and use ENERGY (ATP).

WhatWhat’’s the Connection?s the Connection?Look over the diagram on pg. 96 and read the FIRST paragraph on pg. 97, then answer this question:

What is the relationship between photosynthesis and respiration?

Next we will draw the cycle to show this connection.

Respiration (the whole truth!)Respiration (the whole truth!) Since plants AND animals have living cells,

they both need to do respiration to make energy for those cells.

Plants just make the food that their cells eat!
