Vocabulary A-Z

Let us learn some vocabulary

Photosynthesis
a series of chemical reactions that convert light ener-
gy, water, and carbon dioxide into the food energy Most plants make their own food; a liquid sugar that
molecule glucose and give off oxygen. moves out of food-making cells, enters phloem, and
flows to all plant cells.

Oxygen Carbon dioxide, oxygen, and water vapor pass into
and out of a plant through tiny openings in leaves.
