Has the study of chloroplasts been scientific or pseudoscientific?
The scientist Konstantin Mereschkowsky knew in the
early 1900s that plants make their own food by using
sunlight. He also saw tiny parts in plants called
chloroplasts that do not appear in any animals. He
hypothesized that chloroplasts are what help plants
make food. After many more observations of all types of
plants and animals, scientists are convinced today that
chloroplasts make food for plants.
scientific, because a hypothesis and observations
were made and then a conclusion was drawn
O scientific, because scientists made a hypothesis and
conclusion before making any observations
O pseudoscience, because a hypothesis was believed
to be true before any observations were made
Opseudoscience, because beliefs in chloroplasts are
based on subjective opinions
