Explain the function of the nucleus, nucleolus and nuclear envelope?
nucleus - controls the cell activities as it contains all genetic information, nucleolus makes ribosomes, nuclear pores allow substances move between the nucleus and cell, nuclear envelope separates from the rest of the cell

What is the difference between RER and SER?
RER has ribosomes on the surface whereas SER doesn't
3 of 13
What is the function of the SER?
to synthesize and process lipids

What does the golgi apparatus do?
processes and packages new proteins and also makes lysosomes
involved in the separation of chromosomes during cell division
7 of 13
explain the process of protein production?
gene that codes for protein is transcribed onto Mrna - passes out of nuclear envelope . Travels to RER and processed. Travels to golgi (further processing). Vesicles are actively transported to membrane where they fuse and release contents

What are the functions of the cytoskeleton?
hold shape of cell, support organelles, strengthen cell and maintain shape, cause cell to move, transport of organelles

What are the differences between prokaryotes and eukaryotes?
Prokaryotes have smaller ribosomes, no nucleus (plasmids of DNA), few organelles and no membrane bound ones, extremely small, DNA is circular

Name some different types of stains?
Mehtlyene blue - universal, Sudan red stains lipids, Eosin stains cytoplasm pink, acetic orcein binds DNA and stains chromosomes dark red
