    Perception We process and interpret the incoming raw data in the light of our past experiences‚ in terms of our current needs and interests‚ in terms of our knowledge‚ expectations‚ beliefs and motives. Perceptual world the individual’s personal internal image‚ map or picture of their social‚ physical and organizational environment. Selective attention the ability‚ often exercised unconsciously‚ to choose from the stream of sensory data‚ to concentrate on particular elements‚ and to ignore others

    Introduction The purpose of this lab is to determine which pigments in a plant support or effect photosynthesis‚ based on starch production‚ which wavelengths of light are involved in photosynthesis‚ and identify plant pigments found in a plant leaf by means of paper chromatography. Life on Earth is dependent entirely on the energy from the Sun‚ not only to keep the planet at a suitable temperature but also to provide the energy required to sustain life. The energy of the Sun‚ in the form of

    Photosynthesis Lab Gizmo website: www.explorelearning.com Class code: EFVNHTVRGY Gizmo Warm-up During photosynthesis‚ plants use the energy of light to produce glucose (C6H12O6) from carbon dioxide (CO2)‚ and water (H2O). Glucose is a simple sugar that plants use for energy and as a building block for larger molecules. A by-product of photosynthesis is oxygen. Plants use some of the oxygen they produce‚ but most of it is released. In the Photosynthesis Lab Gizmo™‚ you

    Photosynthesis vs. Solar Cells When the subject of solar energy is discussed both the ideas and processes of photosynthesis and solar cells are the basis of these conversations. While both are processing or converting light into energy‚ which will be explained further‚ it is the type of energy that is vastly different. Photosynthesis as a process used by certain plants to convert the suns energy into food. When the electromagnetic energy from the sun reaches a green plant the chlorophyll

    In light reactions‚ the goal is to transfer solar kinetic energy to chemical potential energy. This is first done by the absorption of a photon of light. Plant pigments are molecules that selectively absorb light energy at wavelengths. A pigment molecule absorbs a photon of light one of pigments electrons jumps to an energy level further than the nucleus. The electron has more potential energy here. The electron now has raised from the ground state to an excited state. Pigments of photosynthesis 1
