Question

im just not sure about the way sugar and water is moving, not sure how to draw it

1. Assume bacteria are growing in a sugar solution where the concentration of water is greater in the solution than in the cellular cytoplasm. By which mechanism will water enter the cells? Passive transport: osmosis DRAW A PICTURE of a bacterial CELL with LABELS, showing which way sugar is moving. And showing which way water is moving. cell membrane optional flagellon

1. Assume bacteria are growing in a sugar solution where the concentration of water is greater in the solution than in the cellular cytoplasm. By which mechanism will water enter the cells? | Passive transport: Osmosis DRAW A PICTURE of a bacterial CELL with LABELS, showing which way sugar is moving. And showing which way water is moving. Bacterial cell wall Bacterial cell • H₂O ff.7 H₂O Plasma | membrane Sugar molecule – Sugar Water solution Outside the cell: High water concentration LLow sugar concentration Inside the cell: Cytoplasm Low water concentration High sugar concentration H2O + H2O Water moves into the cell Osmosis: Diffusion of water down its concentration gradient through a selectively permeable membrane that is, the water moves from an area of high concentration of water (low concentration of solute) to an area of low concentration of water (high concentration of solute) across a memebrane.

If a cell is placed in a hypotonic solution (a solution with higher water concentration and low solute concentration), water moves into the cell by osmosis and cause osmotic lysis.
