Chapter 3, Problem 33MIC

If mitochondria originated as proteobacteria and chloroplasts are descended from cyanobacteria, where does the rest of the eukaryotic cell come from?

All of the following statements help support the Theory of Endosymbosis EXCEP{T: Group of answer choices mitochondria and chloroplasts have molecules that are found in bacteria but not eukaryotic cells mitochondria and chloroplasts divide just like bacteria do If you gently pull mitochondria out of cells, they can live freely scientists have observed larger cells living symbiotically with small cells living inside them mitochondria and chloroplasts have genes that are like modern bacteria 13

Based on the presence of mitochondria and chloroplast within eukaryotic cells, what organelle do you think originated within eukaryotic cells first: mitochondria or chloroplast? Why?

The endosymbiotic theory pertains to which organelle within eukaryotes because of the presence of 70S ribosomes, circular DNA, and the replication of this organelle independent from mitosis? O 1) nucleus O 2) lysosomes. O 3) golgi 4) endoplasmic reticulum 5: O 5) mitochondria

What is the endosymbiotic hypothesis for the originof mitochondria and chloroplasts? What evidencesupports this hypothesis?

How do scientists know that mitochondria and chloroplasts were likely once free-living prokaryotes?  What theory is explained by this evidence?

Chloroplasts and mitochondria are both unusual in that they have double membranes and contain their own set of DNA. Can you think of any explanations for this observation?

There are several lines of evidence that suggest that chloroplasts and mitochondria were once independent organisms.  Explain in your own words what that evidence is.

Complex cells that contain a nucleus and other organelles are called_______ cells. A compelling explanation for the origin of these complex cells is the_________ hypothesis. One observation that supports this hypothesis is that mitochondria have their own_______.
