Prokaryotic Cell Structure
The organelle which serves as the site of protein synthesis.
What are ribosomes?
The site of ribosome assembly.
What is the nucleolus?
The component of the membrane which functions in cell recognition.
What are carbohydrates/glycolipids/glycoproteins?
The movement of a substance from high concentration to low concentration directly across the phospholipid bilayer.
What is simple diffusion?
The component of the cytoskeleton which is stable and provides structural support and prevents excessive cell strecthing.
What are intermediate filaments?
The structure which provides structural support and prevents excessive loss or uptake of water.
What is the cell wall?
The organelle which functions to receive, package, modify and ship cell products.
What is the golgi apparatus/complex?
The component of the membrane which forms a bilayer.
What are phospholipids?
A transport protein which move two substances in the same direction across the membrane.
What is a symporter?
An intercellular junction which forms as the membranes of two cells are fused together.
What are tight junctions?
The structure used for cell movement.
What are flagella?
The organelle involved in converting food molecules to energy/ATP.
What is the mitochondria?
A membrane protein which receives messages from the outside of the cell.
What is a receptor?
The diffusion of water.
What is osmosis?
As the cell size increases, this happens to the surface area to volume ratio of that cell.
What is decreases?
The region of the cytoplasm in which DNA is located.
What is the nucleoid?
The organelle which is involved in the proper segregation of chromosomes during cell division.
What is the centriole/centrosome?
A membrane protein which provides a passageway for the movement of a molecule from one side of the membrane to the other.
What is a channel protein?
The movement of bulk fluid molecules into the cell using vesicles.
What is pinocytosis?
The theory which explains the presence of two membranes, DNA and ribosomes within the mitochondria and chloroplast.
What is endosymbiosis theory?
Two domains of organisms which are comprised of prokaryotic cells.
What are archaea and bacteria?
The organelle which functions to break down unwanted materials.
What is the lysosome?
A type of lipid which functions to maintain fluidity of the membrane by embedding within the tails of the phospholipid bilayer.
What is cholesterol?
The movement of a substance from low to high concentration using the energy released as another substance travels from low to high concentration.
What is coupled transport?
The type of microscope which would allow you to see the movement of a unicellular protist.
What is a light microscope?
