Parts of Cell

Plasma Membrane

separates internal environment from external environment

Mitochondrion

produces ATP

Ribosome

produces proteins

Nucleolus

produces RNA

Nuclear Envelope

protects DNA inside nucleus, controls what enters & exits nucleus

Cilia

propels substances along cell surface

Microvilli

increase surface area for absorption

Lysosome

intracellular breakdown of substances by digestive enzymes

Centrioles

forms mitotic spindles

Cytoplasm

structural support, site of glycolysis

Flagella

enables cell movement

Rough Endoplasmic Reticulum

membranous network that modifies & folds proteins made by ribosomes

Smooth Endoplasmic Reticulum

produces lipids, stores calcium, detoxifies

Golgi apparatus

modifies & packages ER product for secretion from cell

Nucleus

stores genetic information, controls protein synthesis
