1 DUE TODAY: SYLLABUS/HONOR CODE SIGNED
8.3 Anatomy of a Chloroplast Sponge: Set up Cornell Notes on pg. 9 Topic: 8.3 Anatomy of a Chloroplast Essential Question: How is the chloroplast’s structure directly related to its function? How is the chloroplast’s structure directly related to its function? Key Vocabulary: Photosynthesis Chloroplast Chlorophyll Grana Thylakoids Stroma Vocab of the day. You do NOT need to write down BIOZONE and text pages that match with each day BIOZONE: 88, 314 Text: Digital text: DUE TODAY: SYLLABUS/HONOR CODE SIGNED

2 Objective SWU: the chloroplast’s structure is adapted to its function in photosynthesis SW: Label the parts of a chloroplast using a picture from a transmission electron microscope (TEM)

3 The Chloroplast chloroplast leaf cell leaf Chloroplasts are the organelles where photosynthesis occurs Contain: Chlorophyll, which is a pigment that absorbs light energy. Chlorophyll a Chlorophyll b All of the photosynthetic processes occur within the chloroplast

4 The Chloroplast—Background & Structure
Occur only in algae and plant cells Have an extra outer membrane (double-membrane) Contains their own DNA- in the form of a ring ( called cpDNA) Very near in size to a typical prokaryotic cell Can reproduce independently of the cell

5 Parts of the Chloroplast
Grana- made up of numerous thylakoids “Stack of coins” Granum- singular Thylakoids- flattened membrane sacs with components necessary for the absorption of light “Coins” Chlorophyll in the thylakoid membrane Space in middle called the lumen Stroma- fluid located outside the grana Contains many enzymes and chemicals necessary to complete the process of photosynthesis (Calvin Cycle) Thylakoid

6 Please label each part of this chloroplast

7 Please label each part of this chloroplast
cpDNA thylakoid (singular) Granum (singular) Inner membrane AKA chloroplast envelope Outer membrane Stroma

8 Granum (Singular) Stroma Grana (plural) Thylakoid Plastoglobule
Label your TEM diagram showing the structure of a chloroplast Granum (Singular) Stroma Grana (plural) Thylakoid Plastoglobule *TEM= Transmission electron microscope

9 Stroma Granum Grana Plastoglobule Thylakoid
Label your TEM diagram showing the structure of a chloroplast as seen in electron micrographs Stroma *TEM= Transmission electron microscopy Granum (singular) Grana (plural) Plastoglobule Thylakoid (individual unit)

11 Utilization: The Global Artificial Photosynthesis (GAP) project aims to create an artificial “leaf” within the next decade. An electronic version of the leaf that creates oxygen and hydrogen from water and sunlight has already been invented and will be developed for use in the next decade. “Artificial photosynthesis--the creation, particularly through nanotechnology, of devices capable to doing what plants have done for millions of years - transforming sunlight, water and carbon dioxide into food and fuel.”
