Cell Organelles Review No organelles in prokaryotic cells

Cell Organelles

Review � No organelles in prokaryotic cells � Both plants and animals are eukaryotic cells!

Animal Cell

Plant Cell

Organelles Found in Plant and Animal Cells � Cell Membrane � Nucleus � Nucleolus � Mitochondria � Endoplasmic reticulum � Ribosomes � Golgi apparatus � Vacuoles (small in animals; large in plants) � Lysosomes

The Cell Membrane � Location: Around the outside of the cell � Function: Controls what substances enter and leave the cell � Aka: “plasma membrane”

Nucleus � Location: In the cytoplasm � Function: Directs all of the cell’s activities; stores the chromatin � Aka: “control center”

Nucleolus � Location: In the nucleus � Function: Makes ribosomes � Aka: “little nucleus”

Mitochondria � Location: In the cytoplasm � Function: Produces energy � Aka: “Powerhouse” or “Mighty Mitochondria”

Ribosomes � Location: In the cytoplasm and on the rough ER � Function: Makes protein � Aka: “Protein packs”

Endoplasmic Reticulum (ER) � Location: In the cytoplasm around the nucleus � Function: Modifies materials needed in the cell � Aka: “Fashion designers” Smooth ER (no ribosomes) Rough ER (has ribosomes)

Golgi Apparatus � Location: In the cytoplasm � Function: Sorts and ships materials to the correct parts of the cell � Aka: “the post office”

Vacuoles � Location: In the cytoplasm (large in plants; small in animals) � Function: Storage � Aka: “the closet” Animal Cell Vaculole = small Plant Cell Vaculole = large

Lysosome � Location: In the cytoplasm � Function: Destroys worn out cell parts � Aka: “the death chamber:

Cilia / Flagella � (*animal cells only: not all cells have one of these) � Location: on the cell membrane � Function: help the cell move

Organelles Found in Only Plant Cells � Cell Wall � Chloroplast

Cell Wall � Location: Around the cell membrane of plant cells � Function: Gives the cell shape and protection � Aka: “plant cell armor”

Chloroplast � Location: In the cytoplasm � Function: Photosynthesis: Makes sugar from sunlight (also takes in carbon dioxide and gives off oxygen) � Aka: “mean green sugar machine”
