1
PHOTOSYNTHESIS Autotrophic Process: Plants and plant-like organisms make their energy (glucose) from sunlight. Stored as carbohydrate in their bodies. 6CO2 + 6H2O + sunlight C6H12O6 + 6O2
2
Photosynthesis-starts all ecological food webs!
3
Photo-synthesis means "putting together with light." Plants use sunlight to turn water and carbon dioxide into glucose. Glucose is a kind of sugar. Plants use glucose as food for energy and as a building block for growing. Autotrophs make glucose and heterotrophs are consumers of it.
4
Photosynthesis 6CO2 + 6H2O + energy C6H12O6 + 6O2
Carbon dioxide + water glucose + oxygen sunlight absorbed by chlorophyll 6CO2 + 6H2O + energy C6H12O6 + 6O2 As can be seen from the equation for photosynthesis, the wood, bark, and root came from water and carbon dioxide.
5
Leaves are green because they contain
Plants Leaves are green because they contain the pigment: chlorophyll Leaves have a large surface area to absorb as much light as possible "Thanks for the Glucose!"
6
Chloroplasts make the sugars!
7
PHOTOSYNTHESIS Why do we see green?
Green color from white light reflected NOT absorbed Chloroplast: organelle responsible for photosynthesis Chlorophyll: located within Chloroplast Green pigment
8
Chloroplasts make the oxygen too!
9
In plants and simple animals, waste products are removed by diffusion
In plants and simple animals, waste products are removed by diffusion. Plants, for example, excrete O2, a product of photosynthesis.
10
EQUATION FOR PHOTOSYNTHESIS
WATER OXYGEN 6CO2 + 6H2O + ENERGY C6H12O6 + 6O2 CARBON DIOXIDE GLUCOSE
11
The Calvin cycle Calvin cycle) is the set of chemical reactions that take place in chloroplasts during photosynthesis. The cycle is light-independent energy has been captured from sunlight.
