The video explains osmosis, a crucial process where water moves through a partially permeable membrane from a less concentrated to a more concentrated solution. This process is vital for cells to gain and lose water. It also covers how cells in a diluted solution absorb water until equilibrium is reached.

What is the process called where substances move from a less concentrated area to a more concentrated one through a membrane?

• Evaporation

• Osmosis

• Filtration

• Diffusion

Which type of membrane is involved in the process of osmosis?

• Partially permeable membrane

• Non-permeable membrane

• Permeable membrane

• Impermeable membrane

Why is osmosis important for living cells?

• It helps cells to divide

• It allows cells to gain and lose water

• It provides energy to cells

• It helps in protein synthesis

What happens to a cell when it is surrounded by a more diluted solution?

• It remains unchanged

• It absorbs water until equilibrium

• It releases water

• It shrinks

What is the result of a cell reaching equilibrium in a diluted solution?

• The cell continues to absorb water

• The cell starts to shrink

• The cell stops absorbing water

• The cell bursts
