3.1 Cellular Organization

TermDefinition
Organelles Membrane structures
Microtubules Cylinders of protection molecules that move organelles, chromosomes and cells Made of 13 longitudinal rows of globular protein tubulin Can assemble or dissemble
Endocytosis Vesicle Formation
Vesicle Membrane bounded sac that stores and transports substances in and out of the sack
Nuclear Envelope Double membrane with nuclear pores that encloses nucleus
Chromatin Diffuses threads containing DNA and proteins
Endoplasmic Reticulum Synthesis/modification and transport of substances in the cell Interconnected membranous channels and vesicles
Exocytosis vesicle release, secretions
Polyribosme string of ribosomes that is synthesized same protein
Nuclear Envelope double membrane that separates the nucleus and cytoplasm Surround and contain nuclear DNA
Nuclear Pores Large enough to permit the passage of proteins into the nucleus and ribosomal subunits
Chromatin Contains DNA and protein and RNA Found in nucleus
Chromosomes Chromatin coils into rodlike structures
Nucleoplasm Chromatin semifluid medium
Nucleoli Ribosomal RNA formed here - rRNA rRNA joins w/protein to form ribosome subunits
Polyribosomes or Polysomes Groups of ribosomes or single within the cytoplasm
Endomembrane system the nuclear envelope, the endoplasmic reticulum, the Golgi apparatus, lysosomes, and vesicles
Vesicles Tiny membrane Sacks
Intermediate Filaments Differ in structure and function Tough and resist stress Often form cell-to-cell junctions Joins skin cells in the outermost skin layer
Actin filaments Long, extremely thin fibers Occur in bundles or other groupings Isolated from various types of cells

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
