BIOL-1030 Chapter Notes - Chapter 7: Melvin Calvin, Thylakoid, Light-Independent Reactions
Document Summary
Notes from: textbook: campbell biology: concepts and connections 8th edition. Photosynthesis: conversion of co2 to h2o and sugars/other organic molecules, with o2 as a byproduct. Plants belong to the sub-classification of autotrophs called phototrophs (feed themselves using light) Photosynthesis takes place in the chloroplasts: chloroplasts may have originated from a photosynthetic prokaryote that a eukaryotic cell acquired. Photosynthesis occurs more in leaves: 1mm2 of leaf surface = 500,000 chloroplasts. Parts of the plant, and how it relates to function and mainly, photosynthesis. Green color comes from chlorophyll, which converts solar energy to chemical energy. Chloroplasts concentrated in mesophyll cells (interior green tissue of leave) Stomata: controls gas exchange in plant, tiny pores in leaf. Veins: work like veins in the human body, transport water, and export sugar to other parts of plant.
