UNIT 3  PLANT NUTRITION

Nutrition is one of the basic life processes to all living things. The nutrients that living things obtain provide energy to the organism.

Remember thar nutrition includes to breathe and to eat.

• to BREATHE: exchange of gases in an organism, it is also called RESPIRATION. Plants take oxigen (O2) from the air and release carbon dioxide (CO2), exactly like people do. Plants need to breathe all day and night, exactly like people do.
• to EAT: plants are autotrophos, this means that they can make their own food. The process in which plants make their food is called PHOTOSYNTESIS. Photosyntesis only occurs during the day because it is necessary sunlight.
