Cell Review (pg 6)

Nucleus

• Control center, contains DNA

Nucleolus

• Region within the nucleus that makes ribosomes

Chromatin

• Long strands of DNA found in the nucleus

Nuclear Pore

• Holes in the nuclear membrane. Allows passage of materials into and out of nucleus

Cell Membrane

• Made of a lipid bilayer. Selectively permeable • Membrane structure (draw)

Mitochondria

• Site of cellular respiration. Turns glucose into energy

Golgi Apparatus

• Processes and packages materials for secretion. The “UPS” of the cell

Ribosomes

• Site of protein synthesis

Smooth Endoplasmic Reticulum (SER)

• Transports materials throughout cell, makes lipids, detoxifies poisons

Rough Endoplasmic Reticulum (RER)

• Covered with ribosomes. Transports materials throughout the cell, especially proteins

Lysosome

• Cell “stomach”. Contains digestive enzymes that break down debris, worn out cell parts, and bacteria

Microvilli

• Extensions of the cell membrane. Increase surface area for secretion and absorption

Centrioles

• Form spindle during cell division
