what is the cell wall made of...and what is plasmodesmata?
cell wall is made up of cellulose.
plasmodesmata- are channels that allow movement of water, ions, small molecules and hormones (plants only)
200
The smaller the cell......(describe the amount of material that can go in an out)
more material can move in and out
200
The cell membrane is thought to be semi-permeable, what does this mean?
it will only let in and let out certain materials in order to maintain a constant internal environment
200
This is where polysaccharide synthesis in plants occurs....it is also where packaging and sorting of proteins occurs.
golgi apparatus
200
this protein helps the cell move from place to place
microfiliment
200
Name the three cell junctions in animal cells
tight junctions, desmosomes, gap junctions
300
As a cell gets smaller in volume, describe the amount of metabolic activity.
the metabolic activity increases.
300
What does it mean to have a rigid cell wall?
opposite of flexible, will snap if moved one way too much.
300
describe the process of phagocytosis
process by which macromolecules enter the cell by engulfing it and then enzymes will break down the particle.
300
this protein anchors a structure in place and looks like a rope under a microscope
intermediate filaments
300
describe tight junctions
allows substances to move through spaces between spaces
400
A centrifuge has a few test tubes of blood....after spinning the tubes for a few minutes, where would you expect to find the heavier materials in the blood?
at the bottom on the test tube
400
In prokaryotes, what does the cytoplasm consist of?
cytosol (water and particles) and ribosomes
400
This is where glycogen breaks down, drugs and pesticides are chemically modified, and lipids and steroids production
smooth endoplasmic reticulum.
400
this is the largest protein in the cytoskeleton
microtubules
400
this cell junction keeps cells tightly packed together
desmosomes
500
Which type of microscope would you use to see actual organelles within a cell?
Electron microscope
500
What propels a flagella to move a cell?
the motor protein
500
this is the location of protein synthesis
rough endoplasmic reticulum
500
describe what a doublet is and where you would fine it
it is the arrangement of microtubules (9 + 2) and it is found in cilia
500
how do gap junctions work?
they allow materials to pass between adjacent cells instead of into a space between the cells and then into another cell.
