Why are cellular compartments important? Name 3 components that DIRECTLY interact with one another functionally and how they can be recognized histologically.
|
They separate and compartmentalize different processes within a cell.
1) RER: appears very basophilic b/c of the ribosomes that are attached 2) Nucleus: a)heterochromatic (clumped basophilic chromatin); b)euchromatic (dispersed chromatin) 3) Golgi: chromophobic (devoid of stain), located adjacent to the nucleus |
|
|
Name 4 distinct components of a cell's cytoskeleton and one of the primary functions of each.
|
1) Microtubules: structural, gives support to the whole cell
2) Intermediate filaments: structural, "anchor" organelles to cell 3) Microfilaments: motility 4) Cell membrane: creates a boundary for cell |
