Discovery of Cells
He first described cells
Who is Robert Hooke
what is the phospholipid bilayer
plasma membrane
what is the outer boundary of the cell composed of
what is phospholipids and proteins
what holds all the organelle of the cell
cytoplasm
where are the ribosomes found?
in the RER and free floating in the cytoplasm
The four parts of cell theory
What is: all living organisms are composed of cells; cells are the basic unit of organization; cells come from existing parent cells who pass along genetic information
what is the control center
the nucleus
what does the cell membrane do
organells
what do the ribosomes do
producing proteins
SA/V ratio
What is the Volume increases faster than surface area
what is the simple cell
prokaryotic
what is a phospholipid
flexible allowing small molecules to pass while keeping large ones out
what controls the activity of the cell and stores and transfers genetic material/ what creates parts of the ribosomes
the nucleus/ nucleolus
makes proteins to be used outside the cell
Two types of microscopes
What are the:
Compound light: shines light through
Electron: passes electrons through/bounce off to produce image
what is the complex cell
eukaryotic
what do plants have that animal cells don't
a middle lamella
what is the hereditary material when the cell divides
chromosomes(combination of DNA and RNA)
What is the SER used for
makes lipids and detoxify the cell
Two types of cells
What are:
Prokaryotic (simple)
Eukaryotic (complex)
the fed ex guy of the cell
Golgi bodies
what is the glue that holds the middle lamella together
pectin
what else can the nucleus be called/ what is the nucleus surrounded by
chromatin/nuclear membrane
why is the RER rough
it is rough because ribosomes are fixed on the outside of the membrane
