  • Study Notes

    • The osmotic property is a process that distinguishes living cells from dead cells.
    • It regulates the movement of water in and out of the cell to help it function properly.
    • This process is essential for plants to obtain the necessary nutrients.
    • Plant cells have a cellulose wall that surrounds them.
    • Root cells use osmosis to allow water to enter and enable photosynthesis.
    • Excessive water intake without osmosis leads to turgor pressure and salt accumulation.
    • Turgor pressure makes plants healthy and strong, but salt accumulation can lead to dehydration.
    • Osmosis is different from diffusion as it involves the extraction of dissolved particles and their replacement with solvent particles.
    • Osmosis is a critical process for plant survival and growth.
    • Understanding osmosis is essential for plant growth and maintenance.
