Cell Structure and Function

Control center; directs protein synthesis and cell reproduction

Outer layer of cellulose or chitin that functions as protection or support

Long strand of DNA and protein that contain hereditary information

Lipid bilayer with proteins that regulate what passes into and out of the cell

Vesicles that digest worn-out organelles; play role in cell death

Small assemblies of protein and RNA, often bound to the ER; sites of protein synthesis

Network of internal membranes that forms compartments and vesicles; participates in protein  and lipid synthesis

9+2 arrangement of microtubules; functions in motility or moving fluids over surfaces

Sites of genes for rRNA synthesis; assembles ribosomes

"Power plant" of the cell; sites oxidative metabolism

Vesicles that isolate particular chemical activities from the rest of the cell

Network of proteins filaments; functions as structural support and in cell movement

Packages proteins for export from the cell; forms secretory vesicles

Sites of photosynthesis
