Autotrophs include what? Plants The raw materials used for Photosynthesis include what? CO2 and H2O Products and by-products of photosynthesis do NOT include what? CO2 (includes O2, C6H12O6, and H2O) A thin layer of chromatogram is useful for what? Separating pigments based on their physical characteristics What pigments would you find in a typical leaf? Chlorophyll A, Chlorophyll B, and carotenoid

autotrophs an organism able to build all the complex organic molecules that it requires as its own food source heterotroph an organism that cannot derive energy from photosynthesis or inorganic chemicals , and so must feed on other plants and animals, obtaining chemical energy by degrading their organic molecules cellular respiration the oxidation of organic compounds to extract energy from chemical bonds dehydrogenation chemical reaction that involves the loss of a hydrogen atom, electro...

Metabolism Sum of all chemical activity Catabolic pathway break down molecules anabolic pathway build more complex molecules

gregor mendel father of modern genetics two things gregor mendel discussed character trait character heritable feature of an organism trait version of a character what did mendel follow? the inheritance of traits in true-breeding pea plants

Why is oil immersion used? To reduce the amount of light rays that are refracted away from the objective lens. It increases numerical aperture and maintains a uniform light speed. increase the resolving power of a microscope. Prevents refraction of light. What parts of the microscope does light travel through? Illuminator-The light source for the microscope.Diaphragm-Controls the amount of light entering the condenser. Condenser lensFocuses light through the specimen. How do you calculate t...
