Centriole
groups of _____ arrangement of the protein fibers. Draw a picture of a centriole in the box.
2. Lysosomes are called ______________________ sacks. They are produced by the ________________ body. They consist
Lysosomes
of a single membrane surrounding powerful _______________ enzymes. Those lumpy brown structures are digestive
_____________. They help protect you by __________________ the bacteria that your white blood cells engulf.
_______________ act as a clean up crew for the cell. Zoom in and draw what you see.
3. Chloroplasts are the site of ______________________. They consists of a __________ membrane. The stacks of disk like
Chloroplasts
structures are called the ______________. The membranes connecting them are the _________________ membranes.
