Protein
200
A nuclear membrane is __________.
Double bi-layered

What is a Ribosome?
Ribosome has two sub units, the large subunit and the small subunit. It is composed of protein and nucleic acid. It takes the RNA and creates an enzyme by using the "template".

What is the difference between Cilia and Flagella
cilia is more like a crew boat with a whole bunch of mini "legs" paddling it along.
Flagella is more like a whip or a fishes tail which allows it to swim along.
300

Exocytosis
400
what is the relationship between centrioles and centrosomes?
a centrosome is a body containing two centrioles. All is the MOTC
400

Microtubule:
fat and short,
spaced out,
had a lumin,
in a tube like formation,
Microfilaments:

400
The nucleus does what?
store house of genes (DNA),
protects DNA,

What is the difference between plant cells and animal cells?
Not in Plant cells:
Lysosomes,
Centrioles,
Flagella,
Not in Animal cells:
Chloroplast,
Large cell vacuole,
cell wall
500
what are the three types of cellular junction?
tight, gap, desmosomes
500
the walking protein
Special proteins, called motor proteins, carry vesicles along the microtubule of the cytoskeleton. The proteins are powered by ATP, allowing them to move in a walk like motion.
500
What is a Chromatin?
A chromatin is a time of chromosome. If a chromosome is a coiled rubber band a chromatin is a stretched out rubber band. They are both DNA and are both stored in the nucleus
