Cell Membrane "Plasma Membrane" - Correct answer ✔Surrounds the cell
| | | | | | | | |
Composed of phospholipid & protein
| | | |
Semi-permable - Correct answer ✔provides a selective barrier that regulates
| | | | | | | | | |
transport of substances into and out of the cell.
| | | | | | | |
Cytoplasm "Cytosol" - Correct answer ✔Clear liquid enclosed in the cell

Includes: Vacuoles & Vesicle
| | |
,Vacuole - Correct answer ✔Big "vesicle"
| | | | | |
Store water & waste
| | |
Storage sacs |
Helps regulate the amount of liquid in the cell
| | | | | | | |
Vesicles - Correct answer ✔Small membrane sac
| | | | | |
Storage & transport
| |
Carrying protein & some material
| | | |
Store various neurotransmitters
| |
Nucleus - Correct 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 - Correct answer ✔Contained in Nucleus
| | | | | |
Nuclear body that assembles ribosomes
| | | |
Produces rRNA & nucleotides | | |
Chromatin - Correct 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 - Correct answer ✔Fluid portion that contains important proteins
| | | | | | | | |
Nuclear envelope - Correct answer ✔Doubled layered membrane
| | | | | | |
Nuclear pores - Correct answer ✔small holes in the nuclear envelope
| | | | | | | | | |
Allow transport of Rna & ribosomal proteins moving from nucleus to cytoplasm
| | | | | | | | | | |
Endoplasmic Reticulum - Correct answer ✔"Highway system" | | | | | |
Rough ER & Smooth ER
| | | |
Contains ribosomes |
Ribosomes - Correct answer ✔"Protein Factories"
| | | | |
Composed of protein and RNA which synthesize protein
| | | | | | |
Golgi apparatus - Correct answer ✔"Processing & packaging center"
| | | | | | | | |
Fxn: sorts, condense, packages & delivers proteins from RER
| | | | | | | |
Mitochondria - Correct answer ✔"Powerhouse of the cell" | | | | | | |
, Release energy from food molecules & transform energy into ATP ( adenosine
| | | | | | | | | | | |
triphosphate)
Lysosomes - Correct answer ✔"Sewer system" | | | | |
Destroys worn cell parts | | |
Produced by golgi apparatus | | |
Contains hydrolytic & digestive enzymes capable of digesting substance that
| | | | | | | | | |
enter cells |
Cytoskeleton - Correct 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 - Correct answer ✔Cell motility | | | | |
Delicate, threadlike |
Specialized protein, arranged in meshwork bundles | | | | |
Microtubules - Correct answer ✔Thick & stiff hollow tubes that make up the | | | | | | | | | | | | |
cilia, flagella, centrioles and spindle fibers.
| | | | |
Form cell's internal skeleton
| | |
Maintain the shape of the cell | | | | |
intermediate filaments - Correct answer ✔Various type of thicker,threadlike .
