nucleolus

Nucleus

Large usually round or oval organelle enclosed by a double membrane contains DNA

Nucleolus

Dense dark region inside nucleus not membrane bound site of ribosome production

Nuclear envelope

Double membrane surrounding nucleus contains nuclear pores

Cell membrane

Thin outer boundary of cell controls movement in and out

Cytoplasm

Jelly like fluid inside cell membrane but outside nucleus organelles suspended in it

Rough endoplasmic reticulum

Flattened membrane sheets with ribosomes attached usually near nucleus protein synthesis

Smooth endoplasmic reticulum

Smooth tubular membranes without ribosomes lipid synthesis detoxification calcium storage

Ribosomes

Very small dots free in cytoplasm or attached to rough ER protein synthesis

Mitochondrion

Oval or bean shaped organelle double membrane inner folded membrane produces ATP

Golgi complex

Stacked flattened membrane sacs modifies packages and ships proteins

Lysosomes

Small spherical vesicles with digestive enzymes often near Golgi

Centrioles

Pair of short cylindrical structures near nucleus involved in cell division

Proteasome

Small barrel shaped protein complex not membrane bound degrades damaged proteins
