Some unicellular organisms can move and we associate movement with animals, because plants do not move. Unicellular organisms can move by different means. Amoebas for example, simply extend part of their cell in something that looks like a false foot (a pseudopod) and so it extends over the area looking for food. Other unicellular organisma have one or more flagella which are whip like organelles and their movement allows them to slide from one place to another. A third kind of unicellular organism has cilia all around their cell membrane. Cilia are like whiplashes and when they move back and forth they resemble paddles on a boat. Their constant movement allows the cell along to move along in a quite fast way.
Answer: Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
Hope this helps... Stay safe and have a great day/night!!!!! :D
