What is a ribosome?
100
Found in eukaryotic cells. Carry out oxidative metabolism and have their own DNA. Transforms energy in food nutrients into cellular fuel (ATP).
What is the mitochondria?
100
Proposes that some of today's eukaryotic organelles (chloroplast and mitochondria) evolved by a symbiosis between two cells that were each free-living.
What is the endosymbiotic theory?
100
The components of the plasma membrane
What are phospholipids, membrane proteins, and sterols?
100
Has membrane bound organelles/compartmentalization.
What is a eukaryote?
200
The organelle involved in the packaging and distribution of molecules. Vesicles transport these molecules to their destination.
What is the Golgi apparatus?
200
The organelle involved in photosynthesis, found in plant cells.
What is a chloroplast?
200
Proposes that all organisms are composed of cells, cells are the smallest living things, adn that cells only arise from pre-existing cells.
What is cell theory?
200
Restrains the movement of phospholipids at high temperatures and maintains fluidity at lower temperatures by preventing tight packing
What is cholesterol?
200
Possess DNA located in the nucleoid.
What is a prokaryote?
300
Organelle that can be used for storage, contraction, and storage of water. Various functions are dependent on cell type.
What is a vacuole?
300
This organelle has bound ribosomes attached to it. It is involved in the synthesis of proteins to be secreted, sent to lysosomes, or the plasma membrane.
What is the rough endoplasmic reticulum (RER)?
300
Discovered cells
Who is Robert Hooke?
300
The result of a plant cell being put into a hypertonic solution
What is plasmolysis
300
Possess ribosomes.
What is prokaryotes AND eukaryotes?
400
The site of rRNA synthesis
What is the nucleolus?
400
A variety of enzyme-bearing, membrane enclosed vesicles. Peroxisomes are an example of this.
What is a microbody?
400
The "organelle" that was first engulfed in endosymbiotic theory.
What is the mitochondria?
400
Moves substances up their concentration gradient using energy, usually in the form of ATP
What is active transport?
400
Has a single, circular chromosome.
What is a prokaryote?
500
The organelle with a variety of functions, such as synthesis (lipids, etc), storing of calcium, and detoxification
What is the smooth endoplasmic reticulum?
500
The organelle that contains enzymes involved in the oxidation of fatty acids. H2O2 is catalyzed by catalase here.
What is a peroxisome?
500
Does not fit the requirement of being a living organism, because it is not composed of cells.
What is a virus?
500
The six major functions of membrane proteins.
What is transport, enzymatic activity, signal transduction, cell-cell recognition, intracellular joining, and attachment to the cytoskeleton and extracellular matrix?
500
Possess a cell wall that contains peptidoglycan (murein) or a variation of peptidoglycan.
What is a prokaryote?
