Vocabulary
A structure within a eukaryotic cell that has a specific function.
What is an organelle?
These organelles make proteins from amino acids
What are ribosomes?
This is the process a cell uses to expel substances from itself.
What is exocytosis?
The type of transport in which molecules move down their concentration gradient.
What is passive transport?
This is what moves in and out of the cell when it is placed in a tonic substance.
What is water?
The term for a membrane that allows only certain things through it.
What is semi-permeable?
This organelle modifies and packages proteins for transport.
What is the golgi apparatus?
What is fractionation?
What is osmosis?
This is what plant cells have that allows them to maintain their shape despite osmosis.
What is a cell wall?
A protein covalently bonded to a carbohydrate.
What is a glycoprotein?
This organelle, only found in plant cells, stores nutrients and other things absorbed by the cell.
What is the central vacuole?
This is the process used by a cell to bring outside substances into itself.
What is endocytosis?
These are what the cell uses to transport ions across its membrane.
What are ion channels?
This is the type of solution that would cause a cell placed in it to shrivel.
What is hypertonic?
The term for a molecule that contains both hydrophobic and hydrophilic regions.
What is amphipathic?
These organelles use an acidic substance to break down nutrients and non-functioning organelles in the cell.
The process in which a cell envelopes a particle in a vacuole and digests it with a lysosome.
What is phagocytosis?
The term for the process in which a molecule being transported indirectly leads to the transport of a different molecule.
What is cotransport?
This is the process in which the membrane of a plant cell pulls away from the cell wall, causing it to shrivel.
What is plasmolysis?
Junctions that fasten cells into strong sheets.
What are desmosomes?
This is what surrounds the nuclear envelope to maintain the shape of the nucleus.
What is the nuclear lamina?
The process by which a cell takes outside fluid into tiny vesicles
What is pinocytosis?
This is what a cell uses to transport hydrogen ions out of the cell.
What is a proton pump?
This is the term for a cell that has burst due to increased internal pressure.
What is lysed?
