The nucleolus (also called nucleole) is a non-membrane bound structure[1] composed of proteins and nucleic acids found within the nucleus. Ribosomal RNA is transcribed and assembled within the nucleolus.
a part of the cell containing DNA and RNA and responsible for growth and reproduction
tiny particles each made up of rRNA sub units synthesize proteins; a cells protein factories
cillia
short hairlike extensions on a surface of some cells. move substances along surface of the cell
rough endoplasmic reticulum (ER)
membranous network of interconnected canals and sacs some with ribosomes attached (rough ER) and some without attachments(smooth ER)
stack of flattened membranous sacs. chemically processes then packages substances from the ER
mitochondria
membranous capsule containing a large folded membrane encrusted with enzymes contains its own DNA molecule ATP synthesis a cells powerhouse
plasma membrane
phospholipid bilayer studded with proteins. Serves as the boundry of the cell protein and carbohydrate molecules on the outter surface of the plasma membrane.
lysosomes
bubble of enzymes encased by membrane. A cells digestive system
centrioles
pair of hollow cylinders each made up of tiny tubules (function cell reproduction)
flagella
single and much longer projection of some cells. The only example in a human is the tail of a sperm cell.
