Organelles of Eukaryotic Cells
Below is a list of organelles that are commonly found in eukaryotic cells.
||The “brains” of the cell, the nucleus directs cell activities
and contains genetic material called chromosomes made of DNA.
||Make energy out of food
||Make, process and package proteins
||Contains digestive enzymes to help break food down
||Called the "intracellular highway" because it is for transporting
all sorts of items around the cell.
||Used for storage, vacuoles usually contain water or food. (Are you are
thirsty? Perhaps your vacuoles need some water!)
|Plant cells also have:
||Use sunlight to create food by photosynthesis
