Solar-powered calculators, homes, and cars are just a few things that use energy from
sunlight. In a way, you are also solar-powered. Of course, sunlight does not directly
give you the energy you need to play a sport or read this page. That energy comes
from ADP. Molecules of ATP are often made from the breakdown of sugars, but how
are sugars made? Plants capture some of the energy in sunlight and change it into
chemical energy stored in sugars.
A. True
B. False

Chlorophyll (KLAWR-uh-fihl) is a molecule in chloroplasts, shown in
Figure 2.1, that absorbs some of the energy in visible light. Plants have two
main types of chlorophyll, called chlorophyll a and chlorophyll b. Together,
these two types of chlorophyll absorb mostly red and blue wavelengths of
visible light. Neither type absorbs much blue light. Plants have other light-absorbing
molecules that absorb green light, but there are fewer of these
molecules. As a result, the green color of plants comes from the reflection of
light’s green wavelengths by chlorophyll.
A. True
B. False

Some organisms are called producers because they produce the source of
chemical energy for themselves and for other organisms. Plants, as well as
some bacteria and protists, are the producers that are the main sources of
chemical energy for most organisms on Earth. Certainly, animals that eat only
plants obtain their chemical energy directly from plants. Animals that eat
other animals, and bacteria and fungi that decompose other organisms, get
their chemical energy indirectly from plants. When a wolf eats a rabbit, the
tissues of the rabbit provide the wolf with a source of chemical energy. The
rabbit’s tissues are built from its food source—the sugars and other carbon-based
molecules in plants. These sugars are made through photosynthesis.
