module 2, week 1

Are prokaryotic cells and the mitochondria and the chloroplasts are approximately the same size?

Yes (1-10 microns)

DNA and ribosomes are different, how?

Prokaryotic: circular chromosomes and plasmids

Eukaryotic: linear chromosomes

Ribosomes: Diff sizes, pro has 70S while euk has 80S

Are the genetic material and ribosomes of these organelles more similar to those found in prokaryotic cells or eukaryotic cells?

They are more similar to those found in prokaryotic cells.

where you would find an electron transport chain in the eukaryotic cell. Add this to the table.

a) The inner mitochondrial membrane. Functions as a part of cellular respiration. b) The thylakoid membrane in chloroplasts. Functions as part of photosynthesis (light-dependent reactions).

discuss whether mitochondria and chloroplasts share more similarities with a prokaryotic cell or a eukaryotic cell.

Both prokaryotes and the organelles listed here are similar in size, they have similar circular DNA, 70 S ribosomes, and they reproduce via binary fission. Their ETCs are in the membranes surrounding the cell/organelle. Thus, the organelles share more in common with prokaryotes compared to eukaryotes.
