Lesson 6 - Structure of the Chloroplast and Mitochondria
Lesson Objectives
Content Objective: To explain how the structure of the chloroplasts and mitochondria support cell respiration and photosynthesis and how these two organelles can explain the origins of eukaryotic cells.
Language Objective: Create a labelled diagram of chloroplasts and mitochondria to show structure and function.
Syllabus Details:
The origin of eukaryotic cells can be explained by the endosymbiotic theory (1.6)
Annotation of a diagram to indicate the adaptations of a chloroplast to its function
Annotations of a diagram of mitochondrion to indicate the adaptations to its function
Electron tomography used to produce images of active mitochondria
The structure of the mitochondrion is adapted to the function.
Activites
Activity 1
1. Use a piece of A3 paper to represent a eukaryotic cell’s cytoplasm, and different colored paper to represent the different parts of the mitochondria.
Make a poster where you show/explain the following:
a. Label the matrix, cristae, intermembrane space, inner membrane, DNA, ribosomes and outer membrane
b. Where glycolysis occurs & the products and reactants
c. Where the link reaction occurs & the products and reactants
d. Where the Kreb’s cycle occurs & the products and reactants
e. Where the electron-transport chain is located and how it works in a mitochondrial membrane
f. Where the hydrogen ions build up in the mitochondria (include a sentence comparing this to a chloroplast)
g. Where oxygen is used in the mitochondria
h. How chemiosmosis is used to produce ATP.
2. Use a piece of A3 paper to represent a eukaryotic plant cell’s cytoplasm, and colored paper to represent a Chloroplast
Make a poster where you show/explain the following:
a. Outer membrane, granum, lumen, stroma, inner membrane, thylakoids, DNA
b.Where chlorophyll and the “light harvesting complexes” are found
c. Where the light-dependent reaction occurs & the products and reactants
d. Where the Calvin cycle occurs & the products and reactants
e. Where the electron-transport chain is located and how it works in a chloroplasts membrane
f. Where the hydrogen ions build up in the chloroplasts (include a sentence comparing this to a mitochondria)
g. Where Water and CO2 are used in the chloroplasts
h. How chemiosmosis is used to produce ATP.
Activity 2 - Endosymbiotic Hypothesis
Card sort - Endosymbiotic Hypothesis
2. On your posters, annotate the poster to show where evidence exists to support the endosymbiotic hypothesis. Below are some videos to help support you:
a. Bozeman Biology - endosymbiotic hypothesis
b. Endosymbiosis BBC - Interesting - a bit general
