Photosynthesis Part 1
1. Objective: Photosynthesis 11/07/06 Procedure: Site of Photosynthesis Light Energy Chromatography Demo General Homework: Read 8.1 and answer CC questions Honors Homework: Read 7.1, 7.2, & 7.6 and answer CC questions
2. stomata veins Stomata β gas exchange (take in CO 2 , take in and release O 2 ) Veins β carry water and nutrients throughout the plant
6. Light energy contains photons which are particles that have a fixed amount of energy This energy travels in waves The electromagnetic spectrum
7. Visible Light The pigments in our eyes cannot absorb all the wavelengths
8. When light meets matter, it may be Reflected β bounced back OR Transmitted β passed though OR Absorbed The light that is reflected or transmitted determines what color you see When light is absorbed, the energy in light is transferred to the atoms in the molecules of the object absorbing it
10. In order to maximize energy absorption , different pigment molecules are used: 1. Chlorophyll a β reflect green, primary pigment 2. Chlorphyll b β reflect green (some yellow), accessory pigment 3. Carotenoids β reflect red, yellow and orange, accessory pigment (ex. Beta carotene β orange) The reflected green color of the primary pigment, chlorophyll a, masks the accessory pigment colors This is why leaves look green! The light-absorbing pigment molecules found in chlorophyll are only able to absorb light within a narrow range of wavelengths
