Honors Bio
osmosis
Diffusion of water through a selectively permeable membrane
He discovered that all plants were made of cells, which contributed to the development of the cell theory
Matthias Schleiden
facilitated diffusion
Movement of specific molecules across cell membranes through protein channels
exocytosis
Process by which a cell releases large amounts of material
Who was the first person to see cells under the microscope and give them a name
Robert Hooke
He advanced the cell theory with his conclusion that cells could only come from other cells:
Rudolph Virchow
what effects speed of traveling neuron
Temperature axon diameter Myelin sheath
Unlike eukaryotes, prokaryotes do not have
a membrane bound nucleus
Hyper polarization
can stop neuron from working can stimulate
neurotransmitters
can transmit or block neurons go together like puzzle pieces
The word cyto means
cell
This structure serves as the outer boundary of the eukaryotic cell
cell membrane
Which of the following is NOT one of the main components of the cell theory
cells must contain DNA
positive ions
depolarize the neuron
non polar part of phospholipid
fatty acid
active transport
goes low to high - uses energy
hydrophobic
hates water
simple diffusion
high to low
phosphate head
hydrophilic
fatty acids
hydrophobic
negative ions
hyper polarize the neuron
hydrophilic
loves water
Which technology was essential for the development of the cell theory
microscopes
prokrayotic
no nucleus
proteins embedded in membrane are
non polar
eukrayotic
nucleus
Tiny structures that carry out cell functions are collectively called
organelles
polar part of phospholipid
phosphate
stabilizes the membrane
phospholipid
primary membrane components
phospholipids and cholesterol
proteins located out side of the cell are
polar
ion-pumps
pumps used in active transport to help more the materials across membrane
isotonic
regular osmosis
Rudolph Virchow's observations helped to disprove was commonly held belief of the time
spontaneous generation
end of terminal
stores neurotransmitters
end of neuron
terminal
hypotonic
too much water comes into the cell more water on the outside
hypertonic
too much water leaves the cell more water inside
co transport
two substances at the same time that move each other along
