Plants are living things. Plants are not animals, so most do not need to eat other living things to live, with the exception of certain carnivorous plants such as the Venus Flytrap or the predatory pitcher plant. They are usually fixed to one location in the ground.

Plants make food for themselves using sunlight, water, certain minerals (nitrogen, potassium and phosphorous), and carbon dioxide. They are one of five big groups (kingdoms) of living things.

Plants grow upward. The energy from the sunlight pulls the water and food from the ground through the roots, and toward tiny holes at the other end of the plant. These little holes are mostly on the plant's leaves. This is called transpiration.

The word "plant" can also mean to put something in the ground. For example, farmers plant seeds in the ground.

Plants need sunlight to grow. If plants are grown without sunlight they usually turn yellow from decreased chlorophyll production and stretch for the light. This is because they are looking for sunlight which boosts the plant's chlorophyll levels which, in turn, help it grow.
