Prokaryotes
Grab Bag
100
Its main function is to store and protect the cell's "blueprints."
What is the nucleus?
100
This structure is known as the recycling center of the cell.
What is a lysosome?
100
Mitosis is defined as this; therefore only eukaryotes can possibly divide by mitosis.
What is the division of the nucleus?
100
Prokaryotes don't have this.
What is a nucleus?
100
These proteins act as catalysts, lowering the activation energy of essential chemical reactions in the cell.
What are enzymes?
200
The rough E.R. is studded with these tiny structures that are responsible for the production of proteins.
What are ribosomes?
200
Here is where lipids are synthesized and then chemically modified.
What is the smooth E.R.?
200
This stage of mitosis is characterized by the separation of sister chromatids as they are pulled toward opposite ends of the cell.
What is anaphase?
200
Prokaryotes are capable of growing their populations exponentially in a very short amount of time due to this method of reproduction.
What is asexual reproduction?
200
This is probably Donald Trump's favorite plant cell-specific structural feature.
What is a cell wall?
300
Organelles are separate areas of the cell, each of which performs distinct functions vital to the cell's survival. Organelles and their different functions are compartmentalized by this common structure.
What is a membrane?
300
At the cellular level, plants and animals, although both eukaryotic, exhibit several key differences in structure. These two organelles distinguish plant cells from animal cells.
What are chloroplasts and the central vacuole?
300
Chromatin is condensed, the nuclear membrane begins to dissipate, and the centrioles begin to move toward opposite poles of the cell.
What is prophase?
300
Prokaryotes are not capable of dividing by mitosis. Instead, their cellular division is termed this.
What is binary fission?
300
Relative to the interior concentration of a cell, this type of solution would result in water moving equally into and out of the cell across its semipermeable membrane.
What is isotonic?
400
Protein synthesis is an essential part of normal cell activity and many organelles contribute in some way to this function. This is the site within the cell at which ribosomes are created.
What is the nucleolus?
400
The chemical equation C6H12O6 + 6O2 --> 6CO2 + 6H2O + 30ATP represents the process of cellular respiration. This process takes place in this organelle.
What is the mitochondrion/mitochondria?
400
Chromosomes align with this at the center of the cell just before being pulled apart by the microtubules of the centrioles.
What is the metaphase plate?
400
This scientist discovered "animalcules" in water droplets; it is possible that he actually observed single-celled prokaryotes.
Who is Leeuwenhoek?
400
This type of active transport involves large molecules being enveloped by the cell membrane and taken into the cell within a vesicle.
What is endocytosis?
500
These organelles are responsible for the production of the network of microtubules and microfilaments that allow materials to be transported easily around the cell.
What are the centrioles?
500
The nuclear membrane, E.R., Golgi apparatus, vesicles, and main cellular membrane are all components of this system, meaning their membranes are compatible with each other, and materials can easily be transported between them.
What is the endomembrane system?
500
The microtubules produced by the centrioles must "grab onto" these specialized structures of the chromosomes, one per chromatid.
What are kinetochores?
500
"Kills 99.9% of germs!" This .1% can cause devastating infections and hospitals, in particular, are always taking precautions against the rise of these nasty prokaryotes.
What are antibiotic-resistant bacteria?
500
This is the process of the cell breaking down its own organelles either as part of programmed cell death or in order to reuse some of the materials elsewhere in the cell.
What is autophagy?
