Parts of the Cell Flashcards
(32 cards)
Plasma Membrane
Location: External boundary of the cell
Function: Confines cell contents; regulates entry and exit of materials
“GATEKEEPER” selectively permeable
Lysosomes
Location: All throughout cell
Function: Degrade material of cell
“garbage collector”
Mitochondria
Location: Scattered all throughout the cell
Function: Control release of energy from foods, form ATP, powerhouse of cell, ENERGY
Microvilli
Location: Projections of the plasma membrane
Function: Increase the membrane surface area
Finger like structures
Golgi Apparatus
Location: Near the nucleus
Function: Packages proteins
FINAL INSPECTOR
Nucleus
Location: In the middle/center
Function: Stores genetic material (DNA), Headquarters of cells
Centrioles
Location: Two rod-shaped bodies near the nucleus
Function: Direct formation of the mitotic spindle
Nucleolus
Location: Center of the nucleus
Function: Makes ribosomes (proteins), where RNA is made
Smooth ER
Location: Cytoplasm
Function: Synthesize lipids
CLEAN OUT LIVER
Rough ER
Location: Cytoplasm/Nucleus
Function: Synthesize proteins
Tunnel way through cell
Ribosomes
Location: Attached to membrane systems or scattered in the cytoplasm
Function: Synthesize proteins
Chromatin
Location: Nucleus
Function: DNA
Non-dividing
Peroxisomes
Location: Scattered in cytoplasm
Function: Detoxify alcohol, hydrogen peroxide, etc.
Inclusions
Location: Near smooth ER
Function: Adjust cell environment
Ion Channel Protein
Potassium ion to get inside of cell
Head/Tail
Hydrophyllic/Hydrophobic
What are the pancake like structures called?
Cistarnae
Cilia

Nuclear Pores
Land on Rough ER from nucleolus
Cytoplasm
Surrounds organelles
Label the head, collar, and tails
