HEY
does anyone have the genetics test
the multiple choice one cuz i only have one page of it
and he usually puts previous questions on the final like he did on the midterm so if anyone has
it cud they like scan it and then send it again with answers circled??
i wud scan the first page but i dont have a scanner

thanks

ENDOSYMBIOTIC THEORY

--eukaryotic cells evolved from prokaryotic cells
--some believe that mitochondria and chloroplasts were dervied from prokaryotic cells taken up by a larger cell
--believed that eukaryotic cell took up these and by chance, the cells survived
--mitochondria originally aerobic heterotrophic bacteria
--chloroplasts oringially cynobacteria

5 PIECES OF EVIDENCE

1. both similar to bacteria in structure and size
2. both organelles bounded by double membrane (possibly one from vesicle, one from plasma membrane of prokaryotic cell)
3. both have genetic material and divide by splitting, their DNA is structurally like prokaryotes
4. have their own ribosomes
5. RNA base sequence of their ribosomes are like prokaryotes

(also possible that prokaryotic cell flagella became the spindle of centrioles)

Thank you sara

lol

O.O do we need to know all of this?

Or just what Mr. Smirk said during his review session?

Thanks!

oh oh oh could someone write a summary of the review session for me? like just what topics you guys covered?
i would've gone but i had to go to the doctor...

- cellular respiration and photosynthesis -- just basics, what goes in and out (look at my study guide for cellular respiration, if you like)

-- diffusion, VERY briefly, though -- we talked about concentration gradient, I believe.

-- light and dark reactions

 

I left after that, someone else continue! :)

here's another vid for cell resp, it's animation like smirk's but not interactive

here's also some other sites i found w. explanations and stuff
