Photosynthesis and Respiration: Drawing, Riddle, Analogy
Objective 1:
a.
Recognize the importance of photosynthesis in using light energy as part of the chemical process that builds plant
materials.
b.
Explain how respiration in animals is a process that converts food energy into mechanical and heat energy.
c.
Trace the path of energy from the sun to mechanical energy in an organism (e.g., sunlight -light energy to plants by
photosynthesis to sugars - stored chemical energy to respiration in muscle cell - usable chemical energy to muscle
contraction- mechanical energy).
1.
DRAW the relationship between photosynthesis and cellular respiration. Your diagram has to be
correctly labeled with the following terms. Draw arrows to represent the “flow” of energy;
things going “in” and “out.”

2.
Write a RIDDLE based on photosynthesis or respiration. The answer to the riddle should be
photosynthesis or respiration! You must use factual information to support the riddle. Refer to
notes and a text book.
Example: What is invisible, but all around us? Answer: atoms

ANSWER:
3.
Write an ANALOGY that illustrates how respiration and photosynthesis are related. An analogy
is a way to compare two processes by using the format:
“A __________ is to __________as a __________ is to __________.”
Example: An atom is to a molecule as a cell is to an organ.
