Cytology
How many and what are the type(s) of cells?
2 broad types of cells. Prokaryotic and eukaryotic.
Prokaryotes DO or DON'T have a nucleus?
Prokaryotes DON'T have a set nucleus.
Eukaryotes DO or DON'T have a nucleus?
Eukaryotes DO have a true nucleus.
The "brain" of the cell is what type of organelle and found in what type of cell?
The brain of the cell is the nucleus found in eukaryotic cells.
What is tonicity?
Tonicity is the amount of dissolved solutes.
What is cytology?
Cytology is the study of cells.
Cyto=cell
logy=study of
Nucleoid is what in prokaryotes?
The nucleus in eukaryotic cells is contained in?
The nucleus in eukaryotic cells is contained by the phospholipid bilayer.
Do prokaryotic or eukaryotic cells contain a cell wall?
Prokaryotic cells have a cell wall.
What is movement of water and concentration of each?
Isotonic= ?
Hypotonic= ?
Hypertonic= ?
Isotonic= water movement and solutes are balanced.
Hypotonic= solute concentration is lower in extracellular fluid, water diffuses into cell. (swells the cell)
Hypertonic= solute concentration is higher in extracellular fluid, water diffuses out of cell. (shrinks the cell)
Do prokaryotic and eukaryotic cells have a nucleus and organelles?
Prokaryotic cells DON'T have a nucleus and have few organelles.
Eukaryotic cells HAVE a nucleus and multiple organelles.
Plasmid found in prokaryotes are...?
Plasmid found in prokaryotic cells is circular DNA.
Special structures-- ? -- perform specialized functions.
Special structures-- organelles -- perform specialized functions.
What is the function of the mitochondria?
The function of the mitochondria is to make energy for the cell, this comes from cellular respiration.
Solutes= ?
Solvent= ?
Solutes in Solvent= ?
Solutes= substance being dissolved (sugar)
Solvent= dissolves the substance (water, fluid)
Solutes in Solvent= solution
The nucleus is the brain of the cell enclosed in?
What is the name of the "tail-like" rudimentary organelle on prokaryotic cells?
Flagellum
In eukaryotic cells DNA is in a central area compacted into?
DNA in a central area is compacted into chromosomes found in the nucleus of eukaryotic cells.
What are ribosomes?
Ribosomes is the site of protein synthesis, they bind to the rough er, and float freely.
Diffusion is the movement of molecules from an area of (lesser/higher) concentration to an area of (lesser/higher) concentration?
Diffusion is the movement of molecules from an area of lesser concentration to an area of higher concentration.
Prokaryotic and eukaryotic cells are found in?
Prokaryotic cells are found in bacteria, archaea, etc. Eukaryotic cells are found in fungi, plants, animals, and humans.
What are the 3 main prokaryotic bacterial cells?
Coccus, Bacillus, and Spirillum (spirochete).
Is eukaryotic cells single-cellular, multi-cellular, or both?
Based on the cellular model what is the smooth er and rough er?
What are there functions?
Smooth er is the blue WITHOUT the red dots, the rough er is the blue WITH the red dots.
Rough er- makes proteins
Smooth er- makes lipids
Osmosis is the diffusion of water across ?, meaning?
Osmosis is the diffusion of water across a selectively permeable membrane, meaning only certain things can get through (water).
