GENERAL BIOLOGY 1 Ms. Kristine Vaydal  Identify the Discuss the role of structures of pigments in chloroplast photosynthesis Examine the different pigments present in plants through a simple paper chromatography experiment. Autotrophs Organism that can produce its own food using light, water, carbon dioxide.  Heterotrophs - Consumers an organism that eats other plants or animals for energy and nutrients. The term stems from the Greek words hetero for “other” and trophe for “nourishment”.  A metabolic process wherein light energy is transformed into chemical energy. Organelle that contains the photosynthetic pigment chlorophyll that captures sunlight and converts it into useful energy.  Pigment - containing plastids; site of photosynthesis Double-membraned Contain their own DNA and capable of reproducing Found in green tissues of plants.  Freely permeable to small molecules Highly selective; contains transporters such as integral membrane proteins.  Protein-rich ground substance Contains enzymes, starch granules, chloroplast DNA and Ribosomes  Membrane-bound flattened disks. Stacks of thylakoids (singular “granum”) Connects grana together BIOCHROMES Give colors to flowers, leaves, and fruits. Key role for photosynthesis Controls growth and development. Pigments that can absorb energy from sunlight that in turn would be utilized during photosynthesis. chlorophyll-a chlorophyll-b chlorophyll-c chlorophyll-d carotene xanthophyll
