Chapter 7 A Tour of the Cell -- Part 1. TOPICS: How to study cells Eukaryotic vs Prokaryotic Nucleus and Ribosomes Endomembrane system Other membranous organelles. How do we study cells?. Know the different microscopes and their purposes: Light microscope (what we have at TPHS)
TOPICS: How to study cells
Eukaryotic vs Prokaryotic
Nucleus and Ribosomes
Other membranous organelles
What are the largest organelles/parts of a cell that fraction off into the pellet first? What are the smallest? (last)
See Figures 7.14, 7.16, 8.7
Why aren’t mitochondria and chloroplasts in this group?
The endomembrane system’s interconnectedness. All membranes are the same bilayer.
Fig. 7.14 Notice how the vesicle from the ER fuses with the cis side of the golgi and then the trans side of the golgi fuses with a food vacuole to deliver digestive enzymes.
Know the parts:Stroma = fluidthylakoid membranes = are chlorophyll rich grana = stacks of many thylakoids, site of light reactions (because of chlorophyll.)
