Organelles of the cell Eukaryotic cells

Nucleus Usually the largest organelle in the cell Control center of the cell Directs all activities and contains instructions for everything the cell does

Ribosomes Where the cells make proteins Some are free floating, while others are attached to the endoplasmic reticulum

Endoplasmic Reticulum The endoplasmic reticulum (ER) is a series of folded membranes in which materials can be processed and moved around inside of the cell. The rough Er has Ribosomes attached while the smooth er does not

mitochondria Powerhouse of the cell Energy is released when food is broken down

chloroplast Located in plant cells only Where food is made Contains chlorophyll

Golgi apparatus Sort and package proteins into membrane- bound structures called vesicles

vacuole Cells have membrane-bound spaces called vacuoles for the temporary storage of materials. A vacuole can store water, waste products, food, and other cellular materials.

lysosome Sometimes called “suicide Sacs” contain digestive chemicals that help break down food molecules, cell wastes, and worn-out cell parts.

Cell membrane cell membrane is the protective layer around all cells that regulates interactions between the cell and the environment.

Cell wall tough, rigid outer coverings that protect the cell and give it shape.
