Smooth ER plays different functions depending on the specific cell type including lipd and steriod hormone synthesis, breakdown of lipd-soluble toxins in liver cells, and control of calcium release in muscle cell contraction.

Rough ER appers "pebbled" by electrion microscopy due to the presence of numerous ribosomes on its surface. Proteins synthesized on these ribosomes collect in the ER for transport throughout the cell.

It is enclosed in a double membrane and communicates with the surrounding cytosol via numerous nuclear pores.

Within the nucleus is the DNA resposible for providing the cell with its unique characterisics.

Vacuoles tend to be large in plant cells and play several roles: storing nutients and waste products, helping increase cell size during growth, and even acting much like lysosomes of animal cells. The plant cell vacuole also regulates turgor pressure in the cell. Water collects in cell vacuoles, pressing outward against the cell wall and producing rigidity in the plant. Without sufficient water, turgor pressure drops and the plant wilts.
