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.
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
