nucleus
surrounds the cell and regulates the flow of substances into and out of the cell
plasma membrane
transport or delivery organelle of the cell
endoplasmic reticulum

lysosomes

prokaryotic cells
do not have nucleus
eukaryotic
has nucleus
Mitochondria

photosynthesis
process that provides the basis for the worlds food chains
flagella
extensions from a eukaryotic cell that propel the cell with an undulating, whiplike motion
