within this is the DNA responsible for providing the cell with its unique characterestics

produces ribosomes, which move out of the nucleus and take positions on the rough endoplasmic reticulum where they are critical in protein synthesis.

the "soup" within which all the other cell organelles reside and where most of the cellular metabolism occurs. Though mostly water, it is full of proteins that control cell metabolism including signal transduction pathways, glycolysis, intracellular receptors, and transcription factors.

also called, MICROTUBULE ORGANIZING CENTER (MTOC), it is an area in the cell where microtubules are produced

Each of this is a ring of nine groups of fused microtubules. There are three microtubules in each group.

Front 6

a membrane-bound structure with a single membrane. It is actually a stack of membrane-bound vesicles that are important in packaging macromolecules for transport elsewhere in the cell.

Front 8

Is so named because it appears smooth by electron microscopy. plays different functions depending on the specific cell type including lipid and steroid hormone synthesis, breakdown of lipid-soluble toxins in liver cells, and control of calcium release in muscle cell contraction.

SMOOTH ENDOPLASMIC RETICULUM

Front 9

appears "pebbled" by electron microscopy due to the presence of numerous ribosomes on its surface. Proteins synthesized on these ribosomes collect in the endoplasmic reticulum for transport throughout the cell.
