Exocytosis -
ANSWER
release of substances out a cell by the fusion of a vesicle with the membrane.
Endocytosis -
ANSWER
Uptake of materials into the cell
Endocytosis: Pinocytosis -
ANSWER
"Cell drinking"
Endocytosis: Phagocytosis -
ANSWER
"Cell eating"
Cell Membrane "Plasma Membrane" -
ANSWER
Surrounds the cell
Composed of phospholipid & protein
Semi-permable -
ANSWER
provides a selective barrier that regulates transport of substances into and out of the cell.
Cytoplasm "Cytosol" -
ANSWER
Clear liquid enclosed in the cell
,Includes: Vacuoles & Vesicle
Vacuole -
ANSWER
Big "vesicle"
Store water & waste
Storage sacs
Helps regulate the amount of liquid in the cell
Vesicles -
ANSWER
Small membrane sac
Storage & transport
Carrying protein & some material
Store various neurotransmitters
Nucleus -
ANSWER
Largest, densest organelle
Production of:
DNA: cell's genetic information
RNA: carries info from the DNA to sites of actual protein synthesis in the cytoplasm
"Present in all cells except mature RBC and blood platelets"
Nucleolus -
ANSWER
Contained in Nucleus
Nuclear body that assembles ribosomes
Produces rRNA & nucleotides
Chromatin -
,ANSWER
-Contains chromosomes
-Looks like diffuse stippling when cell is viewed at lower-power microscopically
-complex of DNA & protein
-function is packaging very long DNA
Nucleoplasm -
ANSWER
Fluid portion that contains important proteins
Nuclear envelope -
ANSWER
Doubled layered membrane
Nuclear pores -
ANSWER
small holes in the nuclear envelope
Allow transport of Rna & ribosomal proteins moving from nucleus to cytoplasm
Endoplasmic Reticulum -
ANSWER
"Highway system"
Rough ER & Smooth ER
Contains ribosomes
Ribosomes -
ANSWER
"Protein Factories"
Composed of protein and RNA which synthesize protein
Golgi apparatus -
, ANSWER
"Processing & packaging center"
Fxn: sorts, condense, packages & delivers proteins from RER
Mitochondria -
ANSWER
"Powerhouse of the cell"
Release energy from food molecules & transform energy into ATP ( adenosine triphosphate)
Lysosomes -
ANSWER
"Sewer system"
Destroys worn cell parts
Produced by golgi apparatus
Contains hydrolytic & digestive enzymes capable of digesting substance that enter cells
Cytoskeleton -
ANSWER
Give basic stability to the cell as a whole, functioning like reinforced girders
Also compartmentalizes( sorts out) the cytoplasm, creating preferred "freeways" for the movement
of molecules formed by cellular processes
Microfilaments -
ANSWER
Cell motility
Delicate, threadlike
Specialized protein, arranged in meshwork bundles
Microtubules -
ANSWER
Thick & stiff hollow tubes that make up the cilia, flagella, centrioles and spindle fibers.
Form cell's internal skeleton
