Pick the 3 functions of the cell membrane

• Allows for certain (small) molecules to enter and exit the cel

• transforms light energy into glucose (sugar)

• Provides protection and surrounds the plant and animal cell

• Allows for cells to communicate by sending and receiving chemical messages on the surface of the cell membrane

The photo below is showing which function of the cell membrane?

• Communication: sending and receiving signals on the receptor molecule located on the cell membrane ( the shape must fit like a puzzle)

• Semi-permeable: allowing for small molecules like water/glucose/oxygen and carbon dioxide to enter and exit through the cell membrane

• Protecting the inside of the cell by surrounding the outside of it

Which molecule is able to pass through the semi-permeable membrane?

• starch

• glucose

• lipids

Thinking back at our diffusion lab, which molecules were small enough able to diffuse through the cell membrane?

• Iodine, glucose and starch

• Iodine, glucose and water

• starch, water and iodine

Write the 2 materials were able to enter and exit (diffuse into and out of) the "cell"
