A Tour of the Cell

Mr. Anderson provides a comprehensive tour of the cell, discussing why cells are small, their complexity, and the role of microscopes in studying them. He explains the differences between prokaryotic and eukaryotic cells, highlighting key organelles like the nucleus, ribosomes, and mitochondria. The podcast covers the functions of the endoplasmic reticulum, Golgi body, cytoskeleton, vacuoles, lysosomes, and centrioles, emphasizing their roles in cell structure and function.

Why are cells typically small in size?

• To allow for faster diffusion of materials

• To increase their lifespan

• To fit more cells in a given space

• To reduce energy consumption

What is the role of the cytoskeleton in a cell?

• It stores genetic information

• It provides structural support

• It produces energy

• It synthesizes proteins

How do optical microscopes magnify images?

• Using chemical reactions

• Using sound waves

• Using light and lenses

• Using magnets

Which of the following is a characteristic of prokaryotic cells?

• They contain mitochondria

• They are always multicellular

• They lack a nucleus

• They have a nucleus

What is the primary function of the nucleus in a cell?

• To produce energy

• To control cell activities

• To transport materials

• To provide structural support

What is the function of ribosomes in a cell?

• To synthesize proteins

• To transport oxygen

• To store nutrients

• To break down waste

What is the role of the Golgi apparatus in a cell?

• To generate ATP

• To synthesize lipids

• To modify and package proteins

• To replicate DNA

Which organelle is known as the powerhouse of the cell?

• Nucleus

• Ribosome

• Mitochondria

• Lysosome

What is the primary function of lysosomes?

• To store genetic material

• To digest cellular waste

• To produce proteins

• To transport lipids

What is the function of the smooth endoplasmic reticulum?

• To produce ATP

• To synthesize proteins

• To store calcium

• To detoxify chemicals
