The ability to create energy from the sun and Carbon Dioxide

Plants and other types of organisms are able to use light energy from the sun to produce food. – These species are called AUTOTROPHS- self feeders Other organisms that cannot create their own food must eat plants – These species are called Hetertrophs

Please note that our body needs ATP to carry our bodily processes, but that it is short term energy. Glucose is used to regenerate ATP to allow the body to keep functioning. Glucose is the organic compound animals obtain from plants to create energy.

CO 2 + H 2 O + Energy  C 6 H 12 O 6 + O 2 Balance the equation: What does this look like?!

Make sure to note… Plants need: – Carbon Dioxide – Water – “Sun light” – and a pigment called chlorophyll in the CHLOROPLAST to carry out photosynthesis. Pigment is a light absorbing molecule. Chlorophyll is the plant “pigment”

Lets review.. Respiration happens in the animals cell Mitochondria- this is the energy maker In a plant- the energy is created in an organelle called Chloroplast. This is the energy creator of the plant.

When sunlight excites the electrons in the Chlorophyll, it gains a great deal of energy-

Uses energy to create ATP Steps: 1.Light is absorbed by Chlorophyll in the thylakoid stacks 2.Hydrogen is released during the breakdown of water and is used to create ATP 3.The oxygen is released into the environment as a byproduct

1. CO 2 molecules are absorbed from the atmosphere 2.The carbon is taken out of the CO 2 to react with water to form glucose 3.The O 2 left over is released back into the atmosphere

So… Light dependent reaction: – Takes in H 2 0 and releases O 2 Calvin cycle: – Takes in CO 2 Creates sugar Releases O 2
