Cell Types
This term describes how the plasma membrane allows only certain molecules to pass through
What is semi-permeable or selectively permeable?
In this type of transport, molecules move down their concentration gradient from high to low
What is passive transport?
Membrane bound organelles such as mitochondria and chloroplasts are not found in these cells.
What are prokaryotic cells?
This part of the phospholipid bilayer is nonpolar and hydrophobic
What are the fatty acid tails?
In this type of passive transport, small nonpolar molecules pass between the phospholipids.
What is simple diffusion?
This organelle produces proteins that will be secreted from the cell.
What is attached ribosomes of the rough ER
The direction water will move when a cell with a water potential 0.3 M is placed in a solution of 0.1 M
What is into the cell?
This type of cell has a nucleus, lysosomes, RER and SER.
What is eukaryotic?
This part of the phospholipid bilayer is hydrophilic and charged.
What are the phosphate heads?
The environment where the cell and the solution are the same.
What is isotonic or equilibrium?
This organelle can fuse with a vacuole to destroy or digest unnecessary materials
What is a lysosome
This will likely happen to a cell if the salinity of its environment increases significantly
What is water moving out of the cell?
This type of cell has a cell wall, a plasma membrane, and ribosomes but no nucleus.
What is a prokaryotic cell?
These types of molecules are able to diffuse between the hydrophobic fatty acid tails of the plasma membrane
What are small and hydrophobic
In this type of transport, energy is needed to move molecules in bulk or from low to high concentration
What is active transport?
Sorting and packaging of proteins into vesicles occurs in this organelle.
What is the golgi body/apparatus
In this type of transport, water moves from high water potential to low water potential
What is osmosis?
These are 3 components found in a plant cell but not an animal cell.
What is central vacuole, cell wall, and chloroplasts.
Because water is polar, it crosses the membrane more quickly through these special transport proteins.
What are aquaporins?
This occurs is when a transmembrane protein moves charged molecules such as ions from higher concentrated areas to lower concentrated areas
What is facilitated diffusion?
This organelle produces proteins
What is a ribosome
This term describes an area with high water potential and low solute concentration
What is hypotonic?
