Cell Types
This type of cell has a nucleus and other membrane bound organelles
What are eukaryotic cells
Site where ATP is produced by process of cellular respiration
what are the mitochondria
Movement of solute particles across a selectively permeable membrane
diffusion
The net flow of water in and out of cell when the cell and solution are in equilibrium
equal flow in and out
The substance that causes the other substance to dissolve and create a solution
what is the solvent
lacks membrane bound organelles
prokaryotic cells
Site where proteins are modified, sorted, and packaged
what is the golgi apparatus
the movement of water across a semipermeable membrane
osmosis
Cell = 30% solute, 70% water
Placed in a solution that is 70% solute, 30% water
What will happen to the cell?
The substance dissolved in a solution (ex: salt in salt water)
what is the solute
A unicellular organism that lacks a nucleus. has ribosomes, circular DNA, and may have a cell wall...
bacteria
Maintaining cell homeostasis by controlling what enters and exits the cell is the primary responsibility of what organelle
What is the cell membrane (plasma membrane)
solute moving from area of high concentration to low concentration (without use of energy)
diffusion
Cell = 55% solute, 45% water
Placed in a solution that is 45% solute, 55% water
What will happen to the cell?
Expand (lyse)
A solution that is equal concentration to the inside of the cell
Isotonic
THREE things plant cells have that animal cells do not
1) Cell wall
2) Chloroplast
3) Large central vacuole
When a salivary gland fails to produce enzymes necessary for digestion, this organelle is most likely NOT functioning
What are the ribosomes
Name of two types of active transport AND what they do
Endocytosis = Into the cell
Exocytosis = OUT of the cell
What causes blood cells to lyse?
They were in a hypotonic solution
THREE similarities between prokaryotic and eukaryotic cells
1) DNA
2) Ribosomes
3) Cell membrane
The storage unit of the cell where water and nutrients are held until needed. In plant cells, this organelle gives the cell shape via turgor pressure.
What is the vacuole
TWO reasons a cell may need to use active transport
1) Moving from area of low concentration to high
2) Particle is too big to cross the cell membrane
A solution that is lower in concentration when compared to the inside of the cell
Hypotonic
When the inside of the cell is lower in concentration to the solution, the solution is...
what is hypertonic
