All righty. Prokaryotes: -DNA stored in nucleoid -No membrane-bound organelles -Smaller ribosomes -Higher growth and metabolic rate -Less life time per generation Eucariotes: - Nuclei present, DNA stored in chromosomes -Membrane-bound organelles present -Bigger in size I guess this would be enough b...

Hey, I'm doing some work for my first year of university. I've been asked to explain all the differences between these two cell types. I've already mentioned the main differences, but i'd like your input to make sure I cover everything.
Thanks

Guard cells

I understand that guard cells are the only epydermal cells in the leaf which have chloroplasts. I thought it had to do with making sugar for increasing the water potential and help open the stomata, but i read that there is no evidence suggesting photosynthesis takes place there, and that it is the ...

Turner's Syndrome

Hi guys! It's been a long time. I have a consult. A relative of mine has a mild form of Turner's Syndrome and she wants to have a child in the future but does not want the child to inherit the disease. I wonder if you could suggest some methods for her to get a healthy child. Thanks.

Why did you choose Biology online?

This is supposed to be a thread in which everyone admits the real reason why they started using this site and how they came across it (particularly if it is a funny anecdote). So, who shall begin?

Forum theme

This is just a silly whim i have, but i think that the forum's color should be some kind of chlorophyll green instead of blue, because it kindda fits more with the idea of "BIOLOGY" in my head. Or you could put background images according to the forum instead, e.g. diagrams of the human bo...

Pancreas transplant

I've read in many articles that pancreas transplant, e.g. for diabetics, are not performed unless necessary because they are extrmely dangerous, but i couldn't get a concrete answer as regards why.
