Autotrophs and
heterotrophs
Autotrophs use sunlight to
make their own food.
!
Heterotrophs get their food
by consuming di!erent
organisms.
Chemical energy and ATP
Chemical energy is stored in
their bond by molecules in
food.
!
Energy is transferred by ATP
from the breakdown of food
molecules to cell function.
Van Helmont experiment
He thought the tree that he
planted grew from water but
it didn't , it came from the
carbon in carbon dioxide.
Priestly's experiment
Priestly used a rat with his
experiment. He put the rat
in a bell jar with a candle
and the rat died. Then he
put a plant in with the rat
and fire so the rat didn't die.
It needed oxygen to stay
alive and without the plant
in there with the fire it
wasn't giving o! oxygen.
Jan Ingenhousz experiment
he placed plants underwater
in a transparent container
and saw that the undersides
of their leaves made bubbles
in sunlight.
Photosynthesis and cellular
respiration equations
Light and pigments
Pigments reflect certain
wavelengths of visible light
and make them appear
colorful.
Inside a chloroplast
the chloroplast was made
from an electron micrograph
of a chloroplast from a
higher order plant (Levy)
Explain importance of cellular
respiration to production of ATP
Cells must have ATP because
its the gasoline that powers
all living things.
