Eukaryotic Cell Organelles Kara Stevens

Nucleus Area that contains the DNA

Nucleolus Inside the nucleus Makes ribosomes

Nuclear Membrane The “skin” of the nucleus

Nuclear Pores Small holes in the nuclear membrane that allows materials to pass in and out

Chromatin Loose DNA inside the nucleus

Smooth Endoplasmic Reticulum (E.R.) Transports materials Assembles lipids to transport to cell membrane Tube-like structures

Rough Endoplasmic Reticulum (E.R.) Assembles proteins Transports proteins and other materials Has ribosomes all over the outside of it

Ribosome Small dot-like structure Makes proteins Made in the nucleolus Floats everywhere in cytoplasm and on the rough E.R.

Golgi Body (Golgi Apparatus) Repackages materials for use elsewhere

Lysosome Recycles and gets rid of old pieces of the cell and the organelles Uses enzymes to do this – a natural chemical to speed up reactions

Mitochondria Powerhouse (makes energy) Turns food into energy Cellular Respiration is done here Lots of them in muscle cells; not so many in skin cells

Vacuoles Storage place for extra food and water Plant cell = large vacuole Animal cell = small vacuoles

Cell Membrane Lipid bi-layer Protects the cell Regulates what goes in and out of the cell

Cell Wall Rigid layer on the outside of plant cells Provides strength and structure The only organelle left after the death of a plant (ex: log of a tree)

Cytoplasm Gel-like material that everything floats in Made of mostly water

Centrioles Part of cell reproduction

Microtubules Help give structure to the cell

Chloroplast Green organelle where photosynthesis happens Only in plants Filled with green pigment stacks called Chlorophyll
