Photosynthesis Flashcards
Photosynthesis
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
Autotroph
an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.
Celluar Respiration
Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP), and then release waste products.
Chlroplast
(in green plant cells) a plastid that contains chlorophyll and in which photosynthesis takes place.
Glucose
a simple sugar which is an important energy source in living organisms and is a component of many carbohydrates.
Hetoretroph
an organism deriving its nutritional requirements from complex organic substances.
Produce
: Producers: Photosynthesizing organisms. Producers are any kind of green plant. Green plants make their food by taking sunlight and using the energy to make sugar. The plant uses this sugar, also called glucose to make many things, such as wood, leaves, roots, and bark.
Monosaccharide
any of the class of sugars (e.g., glucose) that cannot be hydrolyzed to give a simpler sugar.
Polysaccharide
a carbohydrate (e.g. starch, cellulose, or glycogen) whose molecules consist of a number of sugar molecules bonded together.
Starch
Starch or amylum is a polymeric carbohydrate consisting of numerous glucose units joined by glycosidic bonds called polymers. This polysaccharide is produced by most green plants as energy storage.
ATP
Adenosine triphosphate (ATP), energy-carrying molecule found in the cells of all living things. ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes.
