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

• / 4

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

• / 4

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

• / 4

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)

• / 4
