Study Notes

BIO116: Week 3 Organelles Overview

Learning outcomes include describing cell organelles and their functions, cell variation based on function, and differences between prokaryotic and eukaryotic organisms
Contact information for Dr. R. Rose provided
Resource link for cell micrographs given
Prokaryotes are single-celled organisms adapted to diverse environments and growth conditions
They have minimal internal organization, lack a nucleus, and contain circular DNA in a nucleoid
Prokaryotes lack histones to protect DNA and divide by fission
The term "prokaryote" derives from "pro" meaning before and "karyon" meaning nucleus
