BIOL 1001 : Exam 3
Document Summary
Steps: co2 + h2o c6h12o6 (glucose)+ o2, energy supplied. What organisms perform photosynthesis: plants, bacteria, prokaryotic, no nucleus, membrane-bound organelles, have layers of membranes within the cells (required for photosynthesis, protists, unicellular, eukaryotic. Plants can do both photosynthesis and cellular respiration in the sunlight, and only cellular respiration without sunlight. Vascular tissue is used to move water and minerals into every cell in the plant. Theory of endosymbiosis: describes the evolution of eukaryotic cells from prokaryotic cells. Photosynthetic pigments: chlorophyll-key photosynthetic pigment, absorbs violet, blue, and red light, reflects green, carotenoids-accessory pigment, absorbs blue and green light, reflects yellow, orange and red, phycocyanins-accessory pigment, absorbs green and yellow, reflects blue and purple. Photosynthesis overview: h20 light-dependent reactions (in thylakoids) o2, energized carriers-atp and nadph light-independent reactions, depleted carriers-adp and nadp+ Xv. chlorophyll is found in the membrane of the thylakoids.
