A&P: Organelles & Functions

Nucleolus

produces and assembles ribosomes

Rough Endoplasmic Reticulum

synthesizes proteins

Smooth Endoplasmic Reticulum

-creates lipids
-synthesis of steroid hormones from cholesterol
-create enzymes that detoxify
-convert glycogen to glucose

Golgi apparatus

A system of membranes that modifies and packages proteins for export by the cell

Lysosome

An organelle containing digestive enzymes

Peroxisomes

Contain oxidase enzymes that detoxify alcohol, hydrogen peroxide, and other harmful chemicals

Vacuole

Cell organelle that stores materials such as water, salts, proteins, and carbohydrates within the cell

Centrosomes and Centrioles

-forming and anchoring the spindle fibers
-involved in cell division

Mitochondrion

produce energy

Microfilament

-help divide the cell during mitosis
-enables a cell to move or change shape

Microtubules

-Spiral strands of protein molecules that form a tubelike structure
-give the cell its shape and structure

Microvilli

-projections that increase the cell's surface area
-help cells get nutrients

Cilia

-locomotion
-Hairlike projections that extend from the plasma membrane and are used for locomotion
