PHOTOSYNTHESIS AND
CELLULAR RESPIRATION
 We will examine the exchange of oxygen
and carbon dioxide between living things
and the environment.

Key Elements
 Chloroplasts Organelles found only
in plant cells that carry
out photosynthesis.
 Mitochondria Organelles found in
plant and animal cells
that carry out cellular
respiration.

Lesson Summary
 Photosynthesis and cellular
respiration are related. How?
 Photosynthesis occurs in the
chloroplast of plant cells.
 Cellular respiration occurs in
the mitochondria of plant and
animal cells.
 Whenever you see an arrow
in our equations, think
“produces”.
 Reactants produce products.
Remember, what one
produces the other one
needs. It is a cycle.
