Cell Exam Flashcards
membrane bound organelles
present in eukaryotes but not prokaryotes
nucleus
present in eukaryotes but not prokaryotes (they have a nucleoid)
where is the DNA found in the cells?
in a prokaryotic cell the DNA is found in the nucleoid but in a eukaryotic cell the DNA is found in the nucleus
structures common to both cells
ribosomes, DNA, cell membrane, and cytoplasm
80s vs. 70s ribosomes
prokaryotes have 70s ribosomes bc they are smaller while eukaryotes have 80s ribosomes bc they are larger
unicellular vs. multicellular
all prokaryotes are unicellular while eukaryotes are unicellular and/or multicellular
nucleus function + description
usually large with a double membrane and surrounded by endoplasmic reticulum
ribosomes function + description
they synthesize polypeptides and are usually small and found in the cytoplasm
RER function + description
a series of connected, flattened membrane sacs that are lined with ribosomes found near the nucleus
SER function + description
a series of connected, flattened membrane sacs found farther from the nucleus
golgi apparatus function + description
flattened stacks that delivers things found close to the cell membrane
lysosome function + description
small spherical organelles that are bound by a single membrane
vesicles function + description
circular membrane bound clumps that contain (proteins) and transport materials within the cell
mitochondria function + description
oval with infoldings of membrane called cristae that produce ATP
chloroplast function + description
produces glucose through photosynthesis in plant cells
