|
| Nucleus |
Membrane bound structure surrounding DNA. Controls the cell.

| Nucleolus |
Small structure within nucleus. Site of ribosomal RNA production.

|
| Flagella, Pili, or Cilia |
Structures used to enable movement of cells or sometimes to propel substances across outer surface of the call. Predominantly protein in composition.

| Chloroplasts |
Double membrane bound organelles. Contains chlorophyll for photosynthesis and DNA.

|
| Vacuole |
Membrane bound area filled with water and assorted solutes. Role in maintenance of water balance of the cell.

|
| Ribosomes |
Small organelles at which protein synthesis occurs. May be free floating or membrane bound.

ribosomes (image/jpg)
|
| Endoplasmic reticulum (ER) - smooth |
Network of flattened membranes forming tunnels. Enzymes assisting synthesis of some lipids and final processing of proteins found here.

|
| Endoplasmic reticulum (ER) - rough |
Similar to smooth ER, but with ribosomes embedded in the membrane. Proteins to be exported from cell produced here.

|
| Golgi apparatus (A.K.A golgi body) |
Stacks of saucer shaped membranes where export proteins are modified and stored prior to entering secretory vesicles for exocytosis.
