13 Cards in this Set

  • Front
  • Back
The green leaf cells between the upper and lower epidermisof a leaf; the primary site of photosynthesis in leaves.
The loss of water to the atmosphere by a plant, through the stomates in its leaves.
Calvin Cycle
The cycle that involves the enzyme rubisco and that causes carbon dioxide to be incorporated, or fixed,in sugars during photosynthesis; uses chemical reactions preveiously converted from light energy.
ATP synthetase
An enzyme complex in the inner membrane of a mitochandrion and the thylakoid membrane of a chloroplast, through which protons flow; the formation site of ATP forom ADP and Pi during phosphorylation
Bundle Sheath
Tightly packed cells surrounding veins in the leaves of C4 plants that receive a rearranged 4-carbon acid in the first stage of C4 photosynthesis; w/in the b.s. cells, CO2 is released and reincorporated by rubisco into PGA
In plants, a noncellular, waxy outer layer covering certain leaves and fruits.
The green pigments of plants and many microorganisms; converts light energy (via changes involving electrons) to chemical energy that is used in biological reactions
nicotinamide adenine dinucleotide phosphate; a hydrogen-carrier molecule that forms NADPH in the light reactions of photosynthesis
A metabolistic pathway in plants that uses O, produces CO2, generates no ATP, and slows photosynthesis output; generally occurs on hot, dry bright days, when stomates close and O concentration in the leaf exceed that of CO2
The opening between two guard cells in the epidermis of a plant leaf through which gases are exchanged with the air.
Light Reactions
The energy-capturing reactions in photosynthesis
Limiting Factors
An enviromental condition such as food, temperature, water, or sunlight the restricts the types of organisms and population numbers that an enviroment can support
Crassulacean acid metabolism; an adaptation for photosynthesis in arid conditions, in which CO2 entering open stomates at night is converted into organic acids that release CO2 during the day when the stomates are closed
