Food Production and You

CD8 M24 - June 22, 2018

LESSON 1

Food Production in Plants

• Photosynthesis - a chemical process that involve carbon dioxide, water, energy and chlorophyll. Its products are Glucose (a carbohydrate) and Oxygen (a gas). During this process, Sunlight powers the chemical reaction in plant cells.

What are needed for Photosynthesis?

• Raw Materials

- Carbon dioxide

- Water

- Minerals

• Energy

- Light (solar)

• Catalyst

- Chlorophyll

• Chlorophyll - the pigment needed for Photosynthesis to take place. It serves as a catalyst.

• A catalyst or "helper" is a substance that cause a chemical reaction to take place but does not become a part of the reaction or the final product.

• Glucose - the primary product of Photosynthesis

• Oxygen is a by-product of Photosynthesis. It comes from water molecules

LESSON 2

Cellular Respiration (Getting Energy to Live)

"All living things aspire, but not all living things breathe"

• Breathing and Respiration are not the same

• All living things aspire

• Cellular Respiration takes place in the Mitochondria

• Breathing is a natural process of taking air in and out of the body

• Respiration is a chemical process and breaking down food to produce energy

• The burning of wood and "burning" of food are similar processes

• ATP is the form of energy produced in cellular respiration

• The Chloroplast is the site for Photosynthesis in plants.

• In the burning of wood, light and heat energy are produced
