Photosynthesis / Respiration Crossword Puzzle

QUESTIONS LIST:

• photosynthesis : the process by which plants use energy from the sun, via chloroplasts, to produce sugars, and oxygen
• chlorophyll : the green pigmentation within chloroplasts.
• chloroplasts : organelles (parts) of plant cells which capture sunlight and use it, along with carbon dioxide and water, to manufacture sugars and oxygen.
• light reaction : the stage of photosynthesis which is powered by sunlight. during this process, the plant makes energy storing compounds which are used in later stages of photosynthesis.
• dark reaction : the stage of photosynthesis which is not dependent on sunlight. the energy storing compounds which were created during the light reaction stage are used to produce sugars, carbon dioxide, and water.
• carbon fixation : carbon dioxide is taken from the atmosphere and is assimilated within the plant's structure.
• energy transformation : the changing of the sun's heat energy into chemical energy.
• light intensity : the strength of the light.
• light quality : this refers to the wavelength of the light.
• light duration : the length of time which the light is available.
• carbon dioxide : a gas which makes up approximately 2.4% of the atmosphere. it is produced by respiration (breathing), and by burning fuels. it is also commonly called the greenhouse gas.
• stomata : a pore found in leaves and stems of plants that allows the exchange of gases
• glucose : a simple sugar plants produce through photosynthesis and use for energy
• transpiration : the loss of water vapor from plants through stomata
• radiant energy : light energy, including all electromagnetic waves such as x-rays, ultraviolet, and microwaves
• chemical energy : energy released by chemical reactions, such as using sugars
