Basic Features of a Cell (4)
- prokaryotic + eukaryotic
-plasma membrane
- fluid substance called cytosol
-chromosomes (carry genes)
-ribosomes (make proteins)
Where is most of the DNA in a eukaryotic cell?
nucleus: an organelle that is bounded by a double membrane.
What domains are prokaryotic cells in?
Bacteria + Archaea
Do Prokaryotic cells have a nucleus?
No Nucleus
Where is DNA in a prokaryotic cell?
Nucleoid: not enclosed by a membrane.
Do prokaryotic cells have membrane-bound organelles?
No
What cells contain cytoplasm?
, Prokaryotic + Eukaryotic
Both types of cells contain cytoplasm bound by the plasma membrane.
What does a prokaryotic cell look like?
typical rod shaped
Prokaryotic Cell Contains:
nucleoid, ribosomes, plasma membrane, cell wall, glycocalyx, flagella, fimbriae
Fimbriae
attachment structures on the surface of some prokaryotes
Nucleiod
Region of prokaryotic cells where DNA is located (NOT enclosed by a membrane)
Ribosomes
complexes that synthesize proteins
Plasma Membrane
-a selective barrier that allows passage of oxygen, nutrients, and waste to service the volume of
every cell.
-membrane enclosing the cytoplasm
Cell Wall
-rigid structure outside the plasma membrane
-ONLY IN PLANT CELLS
