Plants that can produce energy from sunlight through photosynthesis are called photoautotrophs. The process of photosynthesis allows photoautotrophs to use carbon dioxide, water and light energy to produce oxygen and energy in the form of sugar. Not all plants can perform photosynthesis, as some plants called chemoautotrophs derive energy from inorganic compounds in the soil instead of sunlight. While the basic steps of photosynthesis were discovered in the 1600s, the full specifics of the process have yet to be fully understood.

5. Light as an Energy Source
Plants that are able to create energy from
sunlight are known as photoautotrophs. The
term is Greek and means "placing with light."
Not all plants can produce energy from
sunlight. Such plants are called
chemoautotrophs; they instead draw energy
from inorganic compounds in the soil. The
process by which plants turn light into energy
is called photosynthesis. Many of the basic
steps to photosynthesis were discovered as
early as the 1600s by scientists throughout
much of Europe, but the specifics of the entire
process have yet to be completely discovered
or defined.

9. • • There are approximately 250,000 different types of flowering
plants in the world.
• • Wheat is the world’s most widely cultivated plant. It is grown on
every continent except Antarctica.
• • One ragweed plant can release as many as one billion grains of
pollen.
• • Sunflowers have long been used to control weeds in cultivated
fields. They produce a natural toxin
• from their roots that keeps weeds from germinating.
• • There are almost 600 species of carnivorous plants. They capture
and kill prey like small insects and
• then digest and absorb the nutrients. Most carnivorous plants
capture insects, but some species can
• capture frogs, birds, and even small rodents!
