Photosynthesis: the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water
Chloroplast: a cell organelle that contains chlorophyll and in which photosynthesis takes place. Eukaryotic: An organism whose cells contain a nucleus surrounded by a membrane and whose DNA is bound together by proteins Prokaryotic: a unicellular organism that lacks a membrane-bound nucleus Oxidize: combine or become combined chemically with oxygen. Cellular respiration: The chemical process that generates most of the energy in the cell, supplying molecules needed to make the metabolic reactions Mitochondria: an organelle found in most cells; where cellular respiration and energy production occur. Food pyramid: a nutritional diagram in the shape of a pyramid Carbohydrate: a nutrient that provides energy, typically made of sugars or starches Protein: a nutrient that is especially for the growth and repair of body tissue; building blocks Lipids (fat): The body uses fat as a fuel source, and fat is the major storage form of energy in the body. Consumption: the using up of a resource, often used in the context of eating Food: any nutritious substance that people or animals eat or drink, or that plants absorb, in order to maintain life and growth. Glucose: a simple carbohydrate (sugar) that is an important energy source in living organisms and is a component of many carbohydrates ATP: Adenosine triphosphate; a compound that releases energy during the process of cellular respiration Basal Metabolic Rate: the rate at which the body uses energy while at rest to keep vital functions going, such as breathing and keeping warm Calories: a unit used in measuring the amount of energy food provides when eaten and digested: Metabolism: the chemical processes that occur within a living organism in order to maintain life Circulatory System: the body system that circulates blood through the body, consisting of the heart, blood vessels, and blood
