1

Nucleus

Contains genetic material of cell (DNA) and nucleoli; site of RNA synthesis and ribosomal subunit assembly

2

Ribosomes

Site of protein synthesis

3

Rough endoplasmic reticulum (rough ER)

Has many ribosomes attached; site of protein synthesis

4

Smooth endoplasmic reticulum

(Smooth ER)

Site of lipid synthesis; participates in detoxification.

5

Golgi apparatus

Modifies protein structure and packages proteins in secretory vesicles

6

Secretory vesicle

Contains materials produced in the cell; formed by the Golgi apparatus; secreted by exocytosis

7

Lysosome

Contains enzymes that digest material taken into the cell; formed by the Golgi apparatus

8

Peroxisome

Breaks down fatty acids, amino acids, and hydrogen peroxide

9

Mitochondrion

Site of aerobic respiration and the major site of ATP synthesis

10

Microtubule

Supports cytoplasm; assists in cell division and forms components cilia and flagella

11

Centrioles

Facilitate the movement of chromosomes during cell division

12

Cilia

Move substances over surfaces of certain cells

13

Flagella

Propel sperm cells

14

Microvilli

Increase surface area of certain cell
