Question:
organelles
Answer:
membrane-enclosed structures that perform specific functions
Question:
Golgi complex
Answer:
series of interconnected flattened sacs (vesicles) located between the nucleus
and cytoplasmic membrane
- serves as the distribution center of the cell
- proteins may undergo modifications or be packaged before being
distributed
,Question:
The nucleus is the defining organelle of all eukaryotic cells
Answer:
defined by a porous double lipid bilayer that contains the genomic content of
the cell (DNA)
- command center of the cell
Question:
DNA of prokaryotic cells is found
Answer:
within the cytoplasm
Question:
nucleolus
Answer:
site of ribosome synthesis
- within the nucleus
,Question:
Lysosomes
Answer:
membrane-enclosed organelles that contain hydrolytic enzymes capable of
degrading unwanted cellular debris, such as proteins, lipids, nucleic acids,
and polysaccharides
- serve as the waste disposal system of the cell
Question:
Ribosomes
Answer:
responsible for protein synthesis; translates RNA into a protein
- located in the cytoplasm of prokaryotic cells
- attached to the endoplasmic reticulum in eukaryotic cells
, Question:
Mitochondria
Answer:
powerhouse of the cell
- double membrane-enclosed organelles primarily responsible for generating
ATP, a chemical source of energy within the cell
- contain tightly packed folded internal membranes called cristae to
drastically increase the surface area where chemical reactions occur
- number of mitochondria may vary between cell types ranging from zero in
red blood cells to more than 2000 in liver cells
Question:
endoplasmic reticulum (ER)
Answer:
series of membrane-enclosed sacs and interconnected tubes (lumen)
- continuous with the nuclear membrane
- composed of the smooth endoplasmic reticulum (SER) and the rough
endoplasmic reticulum (RER)
