_______ is any of several membrane enclosed structures with specialized functions w/in eukaryotic cells.
|
Organelles.
|
|
The seperation of cell parts by centrifugation - breaks apart major organelles.
|
Cell Fraction.
|
|
Cell lacking membrane-enclosed nucleus/organelles. (bacteria, archaea)
|
Prokaryotic Cell. (simple cells)
|
|
Cell with membrane-enclosed nucleus/organelles. (protists, plants, fungi, animals)
|
Eukaryotic Cell. (big cells)
|
|
Selectively-permeable layer that encompasses cell. Made of phospholipid bilayers.
|
Plasma Membrane.
|
|
The chromosome containing organelle of a eukarytic cell. Also contains most the cells DNA.
|
Nucleus.
|
|
What is the Nuclear Envelope?
|
A double membrane that encloses the nucleus.
|
|
What is the Nucleolus?
|
A specialized structure in the nucleus where ribosomal RNA is synthesized.
|
|
What is a Nuclear Lamina?
|
Net-like array of protein filaments lining inner surface of Nuclear Envelope that helps maintain structure.
|
|
Genetic material complsed of DNA and protein. (unwound and not visible as individual shapes when not in use)
|
Chromatin.
|
|
Protein synthesizer, located free in cytosol or bound to Endoplasmic Reticulum (ER).
|
Ribosomes.
|
|
Collection of membranes inside and around eukaryotic cells. (Smooth ER, Rough ER, Golgi Apparatus, Lysosomes, Vacuoles)
|
Endomembrane System.
|
|
What are Glycoproteins?
|
Proteins with 1+ carbohydrate covalently bonded.
|
|
What is a Transport Vesicle?
|
Tiny membraneous sac in a cell's cytoplasm carrying molecules produced by cell.
|
|
Extensive membraneous network in eukaryotic cells that is continuous with outer membrane.
|
Endoplasmic Reticulum (ER).
