Exploring Osmosis in Plant and Animal Cells

The video explains osmosis, the movement of water through a semi-permeable membrane from a region of higher concentration to lower concentration. It covers the effects of osmosis on plant and animal cells, highlighting how plant cells become turgid in hypotonic solutions and undergo plasmolysis in hypertonic solutions. Animal cells, lacking a cell wall, may burst in hypotonic solutions and shrink in hypertonic solutions. The video concludes with a recap of these concepts.

What is the primary movement in osmosis?

• Movement of water from high to low concentration

• Movement of solutes from low to high concentration

• Movement of solutes from high to low concentration

• Movement of water from low to high concentration

What is required for osmosis to occur?

• Two solutions with different temperatures

• A permeable membrane and two solutions with the same concentration

• A semi-permeable membrane and two solutions with different concentrations

• Two solutions with the same concentration

What happens to a plant cell in distilled water?

• It bursts

• It shrinks

• It becomes turgid

• It remains unchanged

What is the term for the swelling of a plant cell in a hypotonic solution?

• Plasmolysis

• Dehydration

• Turgidity

• Lysis

What happens to a plant cell in a hypertonic solution?

• It undergoes plasmolysis

• It becomes turgid

• It remains unchanged

• It bursts

What is the effect of distilled water on an animal cell?

• It becomes turgid

• It bursts

• It remains unchanged

• It shrinks

What is the term for the bursting of an animal cell in a hypotonic solution?

• Plasmolysis

• Turgidity

• Dehydration

• Lysis

What happens to an animal cell in a hypertonic solution?

• It becomes turgid

• It bursts

• It undergoes plasmolysis

• It shrinks

What prevents a plant cell from bursting in a hypotonic solution?

• The cell wall

• The cell membrane

• The nucleus

• The cytoplasm

What is the main difference between the effects of osmosis on plant and animal cells?

• Plant cells have a cell wall that prevents bursting, while animal cells do not

• Animal cells undergo plasmolysis while plant cells do not

• Animal cells become turgid while plant cells do not

• Plant cells burst while animal cells do not
