What are the differences between animal and plant cells?
Plant cells have plasmodesmata, cell wall and chloroplasts
1 of 13
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
2 of 13
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
4 of 13
What does the golgi apparatus do?
processes and packages new proteins and also makes lysosomes
5 of 13
What are the components of a chloroplast?
thylakoid membranes, intergranal lamella, grana, stroma, double membrane
6 of 13
What are the function of centrioles?
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
8 of 13
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
9 of 13
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
10 of 13
How do you convert to micrometers from millimeters?
X1000
11 of 13
What are the resolutions and magnifications of each microscope?
Light - 0.2 nm and X1500, TEM - 0.0002 nm and X100,000,000, SEM - 0.002 nm and less than X500,000
12 of 13
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
