Explain why a plant cell does not burst when we put it in pure water?
The plant cell absorbs water by osmosis just like an animal cell, but the strong cellulose cell wall prevents it bursting.
The plant cell absorbs water by osmosis just like an animal cell, but the strong nuclear force prevents it bursting.
The plant cell absorbs water by osmosis just like an animal cell, but the strong cell membrane prevents it bursting.
The plant cell absorbs water by osmosis just like an animal cell, but the strong cytoplasm glue prevents it bursting.
Plasmolysis is...
the condition of an animal cell when it has lost so much water that the cytoplasm and vacuole have shrunk, pulling the cell membrane towards the center.
the condition of an animal cell when it has gained so much water that the cytoplasm and vacuole have shrunk, pulling the cell membrane towards the center.
the condition of a plant cell when it has gained so much water that the cytoplasm and vacuole have expanded, pushing the cell membrane towards the cell wall
the condition of a plant cell when it has lost so much water that the cytoplasm and vacuole have shrunk, pulling the cell membrane away from the cell wall
Plasmolysis can be brought about by...
putting a plant cell into a solution that is less concentrated than the cytoplasm and cell sap
putting a plant cell into a solution that is more concentrated than the cytoplasm and cell sap
putting an animal cell into a solution that is more concentrated than the cytoplasm and cell sap
putting an animal cell into a solution that is less concentrated than the cytoplasm and cell sap
