Cell Structures
The type of cell that lacks membrane-bound organelles.
What is a prokaryotic cell?
Movement of molecules from high to low concentration without energy.
What is diffusion?
This organelle is responsible for protein synthesis.
What are ribosomes?
As a cell gets larger,what happens to the surface area to volume ratio?
Decreases
A cell moves the same amount of solutes in and out of a cell, resulting in zero net movement
What is dynamic equilibrium?
Eukaryotic cells contain this type of genetic material organization.
What is DNA enclosed in a nucleus?
Transport that requires ATP to move substances against a gradient.
What is active transport?
This organelle modifies, sorts, and ships proteins.
What is the Golgi apparatus?
The structure of the cell membrane
What is a phospholipid bilayer with embedded proteins and peripheral proteins
This happens to a cell that is placed in a solution with a higher solute concentration than the inside of the cell.
What is the cell will shrink
This structure provides support and protection in plant cells.
What is the cell wall?
Movement of water across a semipermeable membrane.
What is osmosis?
This organelle contains enzymes for breaking down waste.
What is the lysosome?
Folding of membranes (like microvilli) increases this.
What is surface area?
The tonicity that has more solute that the surroundings
What is hypertonic?
The four things all cells have
What is DNA, plasma membrane, ribosomes, and cytosol
Transport using membrane proteins without energy.
What is facilitated diffusion?
This organelle is continuous with the nuclear envelope and involved in protein/lipid synthesis.
What is the endoplasmic reticulum?
This component of the membrane controls fluidity and stability.
What is cholesterol?
What is decrease?
The benefit of compartmentalization in cells.
What is provide a location for enzymatic reactions and increase the surface are for the reactions?
Bulk transport that brings materials INTO the cell.
What is endocytosis?
The theory that states that one prokaryotic cell engulfed another and they had a mutualistic relationship,evolving into organelles.
These types of molecules require a transport protein to more through the membrane,
What is polar, large molecules (or Proteins)
The solute potential of a 0.1 M Nacl solution at 22°C
