Photosynthesis, Respiration, Transpiration
Transcript of Photosynthesis, Respiration, Transpiration
Water evaporates out of leaves!
C6H12O6 + O2 -release of energy-> CO2 + H2O
Chloroplasts- The part of the plant that contains the chlorophyll and completes photosynthesis
This is the process that organisms (animals and plants) use to release energy stored in sugar.
The chemical energy stored in sugar is released when the bonds of the molecule are broken in the presence of oxygen. This lets the energy become thermal and mechanical energy while releasing carbon dioxide and water.
The oxygen and sugar you need both come from plants!
As the plant loses water due to evaporation, it draws more water up from the roots. Controlling how much water it loses allows plants to control the flow of water around the plant!
Plants have small holes in their leaves called stomata. Guard cells open and close the stomata to control transpiration.

CO2+H2O -in sun- > C6H12O6 + O2
Plants move toward or away from a stimulus
Photo means light, synthesis means make; so photosynthesis means making from light
Plants take in carbon dioxide and water. Using the energy from the sun they transform these molecules into sugar and oxygen.
The sugar the plants store to use as energy. All plants contain these sugars. These are the sugars that your body uses for energy!
The oxygen is let off by the plant as a waste product. This is the oxygen you breath! Oxygen makes up 20% of the atmosphere today, but before photosynthesis evolved, oxygen made up 0% of the atmosphere.
The plant gets its water from its roots in the soil and the carbon dioxide enters the leaves through the air (air is about .04% CO2).
Plants will grow in a certain direction as a reaction to outside conditions. For instance, plants in a window will usually grow towards the sun. This means they will lean over AND if the pot is turned, the plant will lean the other way! Plants also respond to gravity; always sending the stem up and roots down.
PLANTS EAT SUNLIGHT!!!
