The Need for Energy
Energy is essential to life. The molecule that stores energy is
ATP or adenosine triphosphate.
The Need for Energy ATP is the energy carrier for the cell.
ATP allows energy to be immediately available for cell processes.
Photosynthesis Photosynthesis is the process that uses
the sun’s energy to make simple sugars.6CO2 + 6H2O C6H12O6 + 6O2
Photosynthesis takes place in the chloroplast of plant and algal cells.
Where are chloroplasts
found?
Photosynthesis Pigments like chlorophyll are required for
photosynthesis to take place. Photosynthetic pigments are stored in the
thylakoids of the chloroplast.
Thylakoid
grana
Vein
Water enters the plant through the
roots and travels up to the leaf through
the veins.
Water then travels to each cell through a process known as OSMOSIS.
Stomata
Carbon dioxide then travels to each cell through a process known as Diffusion.
Carbon dioxide enters the leaf
through the stomata.
Photosynthesis
Photosynthesis happens in 2 phases:Light-dependent reaction
Chloroplast StageElectron Transport Chain
Light-independent reactionCalvin cycleCarbon FixationProduces Glucose
Light Dependent Reaction The Light Dependent Reaction
converts light energy into chemical energy and produces ATP.
The products of the Light Dependent Reaction are used to fuel the Light Independent Reaction.Light
