I might as well make some gold, while doing my homework lol.
So, compare Cyanobacteria with chlorophyta.
Cyanobacteria:
They are aquatic and photosynthetic. They have no membrane bound organelles. They are usually unicellular, but can often grow in colonies. Chloroplasts are derived from proto-cyanobacteria. Their cell walls contain peptidoglycan. They contain Chlorophyll a and other pigments. Kingdom: Monera
Chlorophyta: They contain membrane bound organelles. Stores food as starch. Cell wall is made of cellulose and pectins. Contain typically Chlorophyll a and b.
Why different Kingdoms? They are two different organisms. Chlorophyta contains membrane bound organelles while Cyanobacteria doesn't.
Why do they share some similarities. The Chlorophyta's chloroplast is like the Cyanobacteria itself, and according to theory, could have possibly been a proto-cyanobacteria. This would be why they are similar since the Chloroplast might have been an actual cyanobacteria itself.
They way I would differentiate the two is one has membrane bound organelles while the other doesn't.Quote: Sources: http://hypnea.botany.uwc.ac.za/phylogeny/classif/chloro1.htm http://hypnea.botany.uwc.ac.za/phylogeny/classif/cyan1.htm http://www.ucmp.berkeley.edu/bacteria/cyanointro.html http://fig.cox.miami.edu/Faculty/Dana/cyano.html http://www.botany.hawaii.edu/faculty/webb/bot311/Chlorophyta/Chlorophyta-100.htm

Unicellular vs. Multicellular Multicellular benefits: -Allows you to specialize -each generation allows you to produce a greater number of individuals than just being unicellular. -higher rate of survival for each individuals organism *in construction*

Bow down in position against a polished heel
This is something different, you'll like the way this feels
No time for asking questions, no time for wondering
We've heard enough from you now, we've heard everything
We're gonna play a new game, you'll put on this blindfold
You'll do what we tell you, you'll do as you're told
Used to be the leader but now comes the time to serve
Maybe we'll show some mercy, maybe you'll get what you deserve
Count down to the end, gonna make it come faster
Right around the bend is a coming disaster
Count down to the end, and we're here to get faster
Come on down my friend, it's time to meet your master
