Cell Structure Flashcards
States that all living things are composed of one or more cells
Unified Cell Theory
What components do all cells share?
A plasma membrane, cytoplasm, DNA, and ribosomes
How does a prokaryotic cell differ from a eukaryotic cell?
Prokaryotic cells do not have a nucleus, or any membrane bound organelle
Where is prokaryotic DNA found?
The nucleoid
What allows prokaryotic cells to move or swim?
Flagellum
Area where ribosomes are formed
Nucleolus
The ER that synthesizes lipids
Smooth ER
What is the function of a ribosome?
Assembles amino acids into proteins
The organelle that carries out cellular respiration and generates energy
Mitochondria
What does the plasma membrane do?
Regulates the passage of substances, by bringing in or removing them
Substance between the plasma membrane and the nucleus
Cytoplasm
What is the cytoskeleton?
Network of 3 different fibers that give shape and support eukaryotic cells
What are cilia?
Short hair-like structures used to move entire cells
What does ER stand for and what are the two types?
Endoplasmic Reticulum - smooth SER and Rough RER
Organelle that directs synthesis of ribosomes and proteins, houses DNA
Nucleus
