Photosynthesis
All cells need ___________ to carry out their functions, such as making
proteins and __________________________ into and out of the cell
Plants and other organisms such as ____________________and some
bacteria, use _________________________ to make their own food
Photosynthesis – the _____________________by which a cell captures
______________________ in sunlight and uses it to make food
Nearly all living things obtain energy either __________________ or
__________________ from the energy of sunlight captured during
______________________.
Grass obtains energy directly from the _______________ because it
makes its own food through ____________________. Then the zebra eats
the grass; it gets energy that has been ______________ in the grass.
Lastly, the lion gets _______________that has been stored in the
_________________ – the zebra and lion obtain the sun’s energy
indirectly
An organism that can _________ food is called an ________________
and an organism that __________________manufacture its own food is
called a heterotroph
The_________ Stages of _____________!
During photosynthesis, plants and some other organisms use energy from
the sun to convert carbon dioxide and water into oxygen and sugars
Photo means light, if you take a photograph you need to have light or the
photo is dark.
Stage 1: Capturing the Sun’s Energy
 This process occurs mostly in the _______ – the green color comes
from the________, which are colored chemical compounds that
absorb light (________ are the ______ organelle inside plant cells)
o The main photosynthetic pigment in chloroplasts is
__________________________!
Stage 2: Using Energy to Make Food
 Next, the cell uses the ______________________energy to produce
_______________ - the cell needs two raw materials for this stage –
Water (H2O) & Carbon Dioxide (CO2)
1. The root ___________water from the soil
2. Then the water __________ through the plant’s stem to the leaves
3. Carbon Dioxide enters the plant through the small _____________
on the _______________ of the leaves called the ____________.
4. Once in the leaves, the water and carbon ____________ move into
the ___________________
 Inside the ______________, the H2O and CO2 undergo a complex
series of ________________ reactions – the reactions are powered by
the energy captured in the first stage!!
Oxygen (O2) and _________-carbon sugars (C6H12O6) are produced!
Almost ALL of the ______________________ in the Earth’s air was
produced by ___________________________ things through the
process of _____________________!
Photosynthesis Equation:
6 CO2 +
6 Carbon Dioxide
Light Energy
6 H2O - - - - - - - -> C6H12O6
6Water
1 Sugar
Which two are the reactants?
Which two are the products?
+
6 O2
6 Oxygen
