Eukaryotes
|
true nucleus-definite nucleus. Unicellular or multicellular. Have other organelles.
|

Unicellular
|
single celled

Cytoskeleton
|
internal support structures of cells-long protein fillaments.
|
|

Cytoplasm
|
The organelles, cytosol, and cytoskeleton.

Nuclear Envelope
|
double membrane that surrounds the largest structure in an animal cell.
|
|
|
Ribosome
|
site protein synthesis in cell.
|
|
|
Rough endoplasmic reticulum (RER)
|
a folded up continuation of the nuclear envelope.
|
|
|
Smooth Endoplasmic reticulum (SER)
|
lacks ribosomes. makes lipids. important for lipid synthesis + detoxification.
|
|
|
Nucleolus
|
the area within the nucleus of a cell devoted to the production of ribosomal RNA.
|
|
|
Transport vessicles
|
the membrane lined spheres that move within this network, carrying proteins and other molecules.
|
|
|
Endomembrane system
|
an interactive group of membrane lined organelles and transport vesicles within a eukaryotic cell.
|
|
|
Golgi complex
|
a network of membranes that processes and distributes proteins that come to it from the rough ER.
|
|
|
Lysosome
|
an organelle found in animal cells thay digests worn out cellular materials anf foreign materials that enter the cell.
|
|
|
Mitochondria
|
organelles that are the primary sites of energy consevation in eukaryotic cells.
|
|
|
microfilaments
|
made of protein called actin. serve as a support or "structural" filament in almost all eukaryotic cells.
|
|
|
Intermediate filaments
|
filaments of the cytoskeleton intermediate in diameter between microfilamentsand microtubules.
|
|
|
Microubules
|
the largest of the cytoskeletal filament, taking the form of tubes composed of the protein tubulin.

microtubular extentions of cells that take the form of a large number of active hair-like growths stemming from them.
|
|
|
fagella
|
the relatively long, tail-like extensions of some cells that function in cell movement.
|
|
|
Central vacuole
|
a large watery plant organelle that has many functions, among them the storage of nutrients and the retention and degradation of waste products.
|
|
|
Cell wall
|
an outer protective lining of a plant cell. Makes plasma membrane look rather thin and frail by comparison.
|
|
