TEAS SCIENCE: Cell Structural Organization

Terms in this set (15)

"True kernel"
Eukaryote
"Before the kernel"
Prokaryote
- Synthesize proteins from amino acids
- some are mobile and some are embedded in the rough endoplasmic reticulum
- some cells contain thousands
Ribosomes
- synthesize proteins that's transported outside of the cell
- located near the nucleus and contains layers of membrane
Golgi apparatus or Golgi complex
- sacs used for storage, digestion, and waste removal
vacuoles
- A small organelle within the cell
- has a membrane
- moves materials within the cell
Vesicle
Consist of microtubules that help shape and support the cell
Cytoskeleton
- The thickest part of the cytoskeleton that help support the cell and made of proteins called tubulin
- can lengthen and shorten by polymerization and depolymerization of the tubulin dimers
Microtubules
- liquid material that's within the cell
- contains mostly water but also floating molecules
- not within the nucleus
Cytoplasm/cytosol
- acts as a barrier for the cell
- helps to keep cytoplasm in and substances outside the cell out
- determines what is allowed in and out of the cell
Plasma membrane/cell membrane
- tubular network that contains the transport system of a cell
- fused to the nucleus membrane and extends through the cytoplasm to the cell membrane
Rough Endoplasmic reticulum (has ribosomes on the surface) &
Smooth Endoplasmic reticulum (doesn't not have ribosomes on the surface)
Organelle that breakdown various substances
Lysosomes
- The thinnest component of the cytoskeleton
- composed of actin
Microfilaments
Cylindrical structures that are formed from nine triplets of microtubules arranged in a circle around a hollow center
Centrioles
Organelle formed by two perpendicular centrioles in animal cells
Centrosome
