Understanding Why Cells Are Small

What is the main question Mr. Anderson is trying to answer in the video?

• Why are cells large?

• What are cells made of?

• How do cells reproduce?

• Why are cells small?

In the experiment with paper cylinders, which cylinder was found to have a greater volume?

• The tall and skinny cylinder

• Neither has a volume

• The short and round cylinder

• Both have the same volume

What shape is described as having the greatest volume for the least surface area?

• Cube

• Pyramid

• Cylinder

• Sphere

According to Allen's Rule, how do animals living farther from the equator tend to look?

• Taller and skinnier

• Shorter and stockier

• More colorful

• Larger and heavier

Why is it beneficial for cells to be small?

• To maximize surface area for nutrient and waste exchange

• To minimize energy consumption

• To increase their lifespan

• To make them easier to see under a microscope

What happens to the surface area when a large piece of bark is chopped into smaller pieces?

• The surface area becomes zero

• The surface area remains the same

• The surface area increases

• The surface area decreases

What is one reason cells cannot be infinitely small?

• They would become too visible

• They wouldn't be able to house necessary cellular machinery

• They would lose their color

• They would become too heavy

What is the 'sweet spot' for cell size related to?

• Enhancing visibility under a microscope

• Increasing lifespan

• Minimizing energy consumption

• Maximizing surface area compared to volume

What is the primary reason cells need a large surface area?

• To enhance their color

• To increase their weight

• To facilitate efficient exchange of gases and nutrients

• To store more nutrients

What is the relationship between cell size and the diffusion distance for oxygen and carbon dioxide?

• Larger cells have shorter diffusion distances

• Smaller cells have shorter diffusion distances

• Diffusion distance is the same for all cell sizes

• Cell size does not affect diffusion distance
