1
Photosynthesis & Respiration
2
What is Photosynthesis? The process of photosynthesis is a chemical reaction. It is the most important chemical reaction on our planet.
3
What is the Equation for the Chemical Reaction of Photosynthesis?
4
What is the equation for the chemical reaction of photosynthesis?
5
Six molecules of carbon dioxide react with six molecules of water to form 1 molecule of glucose and six molecules of oxygen.
6
Describe Photosynthesis What do you remember about Photosynthesis? Write it down.
7
Describe Photosynthesis The process of changing light energy to chemical energy Energy stored as sugar Occurs in plants and some algae Plants need a light energy, CO 2, and H 2 O Takes place in the chloroplasts, using chlorophyll, the green pigment in plants
8
What happens during photosynthesis? http://www.johnkyrk.com/photosynt hesis.html http://www.johnkyrk.com/photosynt hesis.html
9
Why is this important to us? We cannot make our own food (glucose, energy), we must get our food from plants. Plants are the first step in the food chain.
10
Why is this important to us? The oxygen released during photosynthesis is necessary for all living things. The release of chemical energy for use by cells.
11
Cellular Respiration – Card Activity Use the cards to show Cellular Respiration’s Chemical Equation
12
What is Cellular Respiration? Once the energy that was in sunlight is changed into chemical energy by photosynthesis, an organism has to transform the chemical energy into a form that can be used by the organism. This process is cellular respiration.
13
Describe Cellular Respiration The breakdown of glucose molecules to release energy Takes place in all living things Is a step by step process
14
Plants use ENERGY from the SUNLIGHT to convert CARBON DIOXIDE (CO 2 ) and WATER (H 2 0) into SUGARS and OXYGEN This is a chemical reaction that uses energy The energy is stored in the molecules of sugar that it makes.
16
What is the chemical equation for cellular respiration?
18
What is Yeast? Yeasts are single-celled fungi. These fungi include: –edible mushrooms –common baker’s yeast used to leaven bread –molds that ripen blue cheese –molds on bread and fruits –molds that produce antibiotics for medical and veterinary use
