BIO181 Worksheet: Photosynthesis
How do light-dependent and light-independent reactions provide food for a plant?
READ THIS: Plants are the original solar panels. Through photosynthesis a plant is able to
convert electromagnetic (light) energy into chemical energy. This energy is used not only to
keep the plant alive, but also to sustain all creatures that rely on the plant for food and shelter.
Plants and photosynthetic algae are also the source of all oxygen on Earth, allowing the
inhabitants of Earth to benefit from our most plentiful renewable energy resource.

1. Consider the organelle illustrated in Model 1.
a. What is the name of this organelle?
Chloroplast
b. Is this organelle more likely to be found in animal cells or plant cells?
Plant cells
2. The structures inside the organelle in Model 1 are called thylakoids. What compound
necessary for photosynthesis is contained in the thylakoids?
Chlorophyll
