Down: 1) a plant that uses the Calvin cycle for the initial steps that incorporate CO2 into organic material, forming a three-carbon compound as the first stable intermediate.2) a plant that prefaces the Calvin cycle with reactions that incorporate CO2 into four-carbon compounds, the end product of which supplies CO2 for the Calvin cycle.3) a light-harvesting unit of a chloroplast's thylakoid membrane; consists of several hundred antenna molecules, a reaction-center chlorophyll, and a primary electron acceptor.4) the production of ATP by chemiosmosis during the light reactions of photosynthesis5) the distance between crests of adjacent waves, such as those of the electromagnetic spectrum6) the warming of the atmosphere caused by CO2, CH4, and other gases which absorb infrared radiation and slow its escape from Earth's surface7) in a plant cell, the breakdown of a two-carbon compound produced by the Calvin cycle. the Calvin cycle produces the two-carbon compound, instead of its usual three-carbon product G3P, when leaf cells fix O2, instead of CO2.8) a thick fluid enclosed by the inner membrane of a chloroplast.13) in a photosystem in a chloroplast, the chlorophyll A molecule and the primary electron acceptor that trigger the light reactions of photosynthesis. the chlorophyll donates an electron excited by light energy to the primary electron acceptor, which passes an electron to an electron transport chain15) an organism that makes organic food molecules from CO2, H2O and other inorganic raw materials22) the green tissue in the interior of a leaf; a leaf's ground tissue system; the main site of photosynthesis Across: 9) the first of two stages of photosynthesis in which solar energy is absorbed and converted into chemical energy in the form of ATP and NADPH10) a pore surrounded by guard cells in the epidermis of a leaf.11) a fixed quantity of light energy.12) a slow but steady rise in Earth's surface temperature, mostly due to increasing concentrations of greenhouse gases14) a plant that uses crassulacean acid metabolism, an adaptation for photosynthesis in arid conditions. Carbon dioxide entering open stomata during the night is converted into organic acids, which release CO2 for the Calvin cycle during the day, when stomata are closed16) the process by which plants, autotrophic protists, and some bacteria use light energy to make sugar and other organic food molecules from carbon dioxide and water17) the incorporation of carbon from atmospheric CO2 into the carbon in organic compounds.18) an organism that makes its own food, thereby sustaining itself without eating other organisms or their molecules.19) a stack of hollow disks formed of thylakoid membrane in a chloroplast; the sites where light energy is trapped by chlorophyll and converted to chemical energy during the light reactions of photosynthesis20) the second of two stages of photosynthesis, a cyclic series of chemical reactions that occur in the stroma of a chloroplast, using the carbon in CO2 and the ATP and NADPH produced by the light reactions to make the energy-rich sugar molecule G3P21) solar energy, or radiation, which travels in space as rhythmic waves and can be measured in photons23) one of a number of disk-shaped membranous sacs inside a chloroplast. These membranes contain chlorophyll and the enzymes of the light reactions of photosynthesis
