Comparing Prokaryotic and Eukaryotic Cells
Prokaryotic cells lack these structures that eukaryotic cells possess.
What are membrane-bound organelles?
Cite of photosynthesis.
What is the chloroplast?
These carbohydrates are covalently bonded to proteins on the extracellular side of the plasma membrane.
What are glycoproteins?
The plant cell wall is primarily composed of this polysaccharide.
What is cellulose?
The process by which molecules spread out evenly into the available space.
What is diffusion?
The region in a prokaryotic cell where DNA is located.
What is the nucleoid?
This structure within the nucleus is where ribosomal RNA is synthesized.
What is the nucleolus?
Membrane proteins that are loosely bound to the surface of the membrane.
What are peripheral proteins?
Cells are embedded in this complex network of proteins and polysaccharides.
What is the extracellular matrix (ECM)?
The type of transport that requires energy to move solutes against their gradients.
What is active transport?
This cellular structure is present in both prokaryotic and eukaryotic cells and is responsible for protein synthesis.
What are ribosomes?
Ribosomes can be found in these two locations within a eukaryotic cell.
What are the cytosol and the rough ER?
These are small membrane sacs that transport materials between organelles in the endomembrane system.
What are vesicles?
The process by which cells take in large molecules by forming vesicles from the plasma membrane.
What is endocytosis?
The type of diffusion that requires transport proteins but no energy input.
What is facilitated diffusion?
Prokaryotic cells typically range in size from 1 to 5 micrometers, while eukaryotic cells are generally within this size range.
What is 10 to 100 micrometers?
This organelle is where lipids, steroids and hormones are synthesized.
What is the smooth endoplasmic reticulum.
This organelle contains hydrolytic enzymes and is involved in digestion and recycling within the cell.
What is the lysosome?
Calculate the pressure potential of water in an open beaker.
What is zero bar?
The type of endocytosis referred to as "cellular eating.
What is phagocytosis?
The two domains of prokaryotic cells are these.
What are Bacteria and Archaea?
Name two organelles that are found in plant cells but not found in animal cells & one organelle found in animal cells but not plant cells.
Found in plant (not animal): chloroplast, cell wall, central vacuole, plastids.
Found in animal (not plant): centrioles, centrosomes, lysosomes (Maybe?)
This molecule within the animal cell membrane helps maintain fluidity at varying temperatures.
What is cholesterol?
A cell with a solute potential of -2.5 bars and a pressure potential of 1.5 bars is placed into an open beaker with a solute potential of -3.5 bars. Will the cell gain or lose water?
The cell will lose water.
The type of endocytosis referred to as "cellular drinking."
What is pinocytosis?
