Agar Cube Diffusion

The video tutorial explores diffusion, where particles move from high to low concentration areas. An experiment is conducted using Agar Jelly cut into a cube and a slab, both with the same volume but different surface areas. Submerged in hydrochloric acid, the slab loses its color faster than the cube due to its larger surface area and shorter diffusion distance. This demonstrates how cell shape and surface area affect diffusion rates, with implications for understanding cellular processes.

What is the primary purpose of the experiment described in the video?

• To investigate how diffusion is affected by cell shape

• To observe the color change in phenolphthalein

• To measure the volume of Agar Jelly

• To test the acidity of hydrochloric acid

Which materials are used to cut and measure the Agar Jelly shapes?

• A saw and a measuring tape

• A scalpel and a compass

• A knife and a ruler

• Scissors and a protractor

What is the initial observation after submerging the Agar shapes in hydrochloric acid?

• The Agar becomes solid

• The Agar turns blue

• The Agar starts to bubble

• The Agar loses its pink color

How long does it take for the slab to become completely clear?

• 50 minutes

• 90 minutes

• 20 minutes

• 70 minutes

Why does the cube take longer to lose its color compared to the slab?

• The cube has a larger volume

• The cube has a smaller surface area

• The cube is made of a different material

• The cube is submerged in a different solution

What factor allows the slab to lose its color faster than the cube?

• Greater volume

• Higher temperature

• Larger surface area

• Different chemical composition

What does the experiment demonstrate about the relationship between cell shape and diffusion?

• Larger cells diffuse faster

• Shape has no effect on diffusion

• Diffusion is faster in spherical cells

• Shape and surface area affect diffusion rates
