Presentation Transcript

  1. Photosynthesis • Who conducts photosynthesis • Plants, algae, some photosynthetic bacteria • Chlorophylls are photosynthetic pigments • They absorb all wavelengths but yellow-green and green. • Chlorophyll a is most abundant; also have b

  2. Photosynthesis • Anthocyanin (fall) and phycobilins (red algae and cyanobacteria) are accessory pigments • They absorb other wavelengths of color • Review: Light travels in waves and is in packets called photons. Photosynthesizers use wavelengths between 380 to 750 nm.

  3. Photosynthesis • Pigments catch the suns energy- by exciting electrons and moving them to higher energy levels. When they fall back to the lower energy level they emit energy that the plant can use to make food or conduct sugar producing reactions.
