Homework Help: Biology

Posted by Sam on Saturday, February 24, 2007 at 4:29pm.

Would someone be kind enough to check the following paragraph for me, I need to complete it by adding the appropriate words from the following list,

Cell walls, mitochondria, nucleus, DNA, eukaryotes, protoctists, endosymbiosis, organelle, membranes, diversity, bacteria, chloroplasts, cytosol.

The words in brackets are the ones I believe to be correct, but would like a second opinion.

Lynn Margulis first proposed that (chloroplasts) evolved by a process of (endosymbiosis) in which (bacteria) developed into (eukaryotes) and (protocists) and eventually lost their independence. Evidence for this is that both types of (organelle) have (nucleus), they also have similar ribsomes and are bounded by (membranes). Also the respiration and photosynthetic abilities of mitochondria and chloroplasts already existed in certain free living bacteria.



1st go to the following site and then see if my changes make more sense:

Lynn Margulis first proposed that (chloroplasts) evolved by a process of (endosymbiosis) in which (bacteria) developed into (mitochondria) and (chloroplasts) and eventually lost their independence. Evidence for this is that both types of (organelle) have (DNA), they also have similar ribsomes and are bounded by (membranes). Also the respiration and photosynthetic abilities of mitochondria and chloroplasts already existed in certain free living bacteria.
