Mostly found in plant cells.Mostly found in plant cells.

Lysosomes

Lysosomes dissolve wasted cells and food for energy for the cell.

They are very small but very efficient.Lysosomes fuse with vacuoles and

dispense their enzymes into the vacuoles.

Rough/Smooth ER

Transports proteins to be used in the cell membrane

Endoplasmic Reticulum is found in all eukaryotic cells

First seen by Keith Porter, Albert Claude, and Ernest F. Fullam in 1945.

Nucleus

The “brain” of the cell.

Contains specific instructions for reproducing.

Found in most eukaryotic cells

Mitochondria

Mitochondria are thought to be descended from ancient bacteria, range from 1-10 millimeters in size.

Generate most of the cell’s supply of ATP.

Golgi Apparatus

Also called the Golgi body, Golgi complex, or dictyosome.

Package and processes proteins and lipids.

Cell MembraneCell Membrane

Also called the Also called the plasma membraneplasma membrane, , plasmalemmaplasmalemma or “phospholipid bilayer.” or “phospholipid bilayer.”
