If I were to conduct this project again I would shine the light on the elodea for 48 hours instead of 16 hours. Because elodea produces oxygen, it too, is a thing that humans need in order to live. Photosynthesis Photosynthesis is the biological process in which sun energy is used to power things made up of carbon dioxide and water. The process of photosynthesis is in green plants, algae and a limited amount of bacteria. Photosynthesis provides two key thing humans, animals, and insects need to survive, glucose and oxygen.
Respiration is the reversed process of photosynthesis.
Plants Plants use the process photosynthesis to grow. The molecule in plants that the process of photosynthesis affects most is the chloroplast and chlorophyll molecule. Chloroplasts are complex green structures within a plant cell that contains chlorophyll pigments and gives plants their green color. Chlorophyll is found in chloroplast leaves. Chlorophyll s job is to trap energy from the sun.
