YOU ARE PREPARED FOR THE CP PHOTOSYNTHESIS TEST
IF YOU KNOW . . .
the complete equation for photosynthesis
6Co2 + 6H20
= C6H12O6
+ O2
the difference between a photoautotroph and a heterotroph
Photoautotroph is an organism that makes its own food using
light energy. Heterotroph is an organism that cannot make its own
food.
the source of energy for photosynthesis
Light energy (sun)
the name for a packet of light energy that is absorbed by the
plant
photon
why plants are green
chlorophyll
which color (from white light) is most absorbed by chlorophyll and
which color is least absorbed by chlorophyll
Green is least absorb and blue-violet is the most absorb
what is the general term for the molecules that absorb sunlight
(HINT . . . they absorb and reflect color)
pigment
which layer of the leaf most of the photosynthetic cells are found
(which contain lots of chloroplast)
Mesophyll (palisade layer)
the parts of the chloroplast (being able to label the diagram)
Look over the picture of the chloroplast
the definitions of thylakoid, grana, and stroma
Thylakoid –- structure inside the chloroplast that contains
chlorophyll. Grana is the stack of thylakoids. Stroma is the fluid
inside the chloroplast
the stomata and
what is its function
The stomata is the opening in the lower epidermis of the leaf.
It allows carbon dioxide to enter the leaf and oxygen to exit the
leaf
the 3 parts that make up a ATP molecule and be able to label those
three parts on a diagram
Adenine - the nitrogen base.
phosphate groups
Ribose –- the sugar molecule.
3
how ADP is formed from ATP
A bond is broken between two phosphates of ATP and energy is
released
the function/role of ATP in a cell
Cell energy
where the oxygen molecule, that a plant releases, comes from
Water molecule
where light reactions and light independent reactions take place
Light reactions take place in the thylakoids and calvin cycle
takes place in the stroma
the products of the light reactions and the products of the light
independent reactions
Look at the diagram that we went over in class.
how many times the calvin cycle must run through in order to make
one glucose molecule
twice
the products of the light independent reactions
Look at the diagram that we went over in class
what carbon fixation means
When a carbon and oxygen from carbon dioxide are incorporated
into an organic molecule
the function of NADP+
Electron carrier (hydrogen carrier)
the other name for the Calvin Cycle
Light independent reactions
