Osmosis and plasmolysis

Turgor pressure A plant cell in hypotonic solution will absorb water by endosmosisso that the increased volume of water in the cell will increase pressure, making the protoplasm push against the cell walla condition known as turgor. Turgor makes plant cells push against each other in the same way and is the main line method of support in non-woody plant tissue. Plant cell walls resist further water entry after a certain point, known as full turgor, which stops plant cells from bursting as animal cells do in the same conditions. This is also the reason that plants stand upright.

Osmosis and plasmolysis

Summary What is Osmosis? Osmosis is a process in which water molecules move from a high concentration to a low concentration across a semipermeable membrane until the water potential becomes equal on both sides.

Osmosis and plasmolysis

In other words, osmosis refers to a process in which water molecules moves from a high water potential area to a low water potential area via a semipermeable membrane until both areas reach the same osmotic potential.

It is a biological process important for solute distribution in cellular environments. Cells have a semipermeable membrane called cell membrane.

Solute and other molecules transport across the cell membrane by osmosis. It is a type of a selective diffusion which happens from high water potential to low water potential spontaneously.

Osmosis What is Plasmolysis? Plant cells have cell walls outer to cell membranes. The cell wall is a rigid structure which decides the shape of the plant cell. When molecules enter or exit the cytoplasm, it undergoes changes.

However, cell wall resists these changes. In a normal state, cytoplasm and cell membrane remain intact with the cell wall of a plant cell. When a plant cell is placed in a hypertonic solution which has a higher solute concentration and a low water concentration compared to the cytoplasm of the cell, water molecules move out from the cell to the outside solution via osmosis.

Cytoplasm shrinks inside due to the water loss. Cell membrane detaches cell wall together with the cytoplasm. This process is known as plasmolysis and the cell is known as plasmolyzed cell as shown in figure If a plasmolyzed cell is placed in a hypotonic solution, it can convert back to the normal state.

Plasmolysis, turgid and flaccid states of a plant cell What is the difference between Osmosis and Plasmolysis? Osmosis vs Plasmolysis Osmosis is defined as a process in which water molecules move from high concentration to low concentration across a semi permeable membrane.

Plasmolysis is a state in which a plant cell is placed in a hypertonic solution and the cell cytoplasm loses its water and shrinks. Water Movement Water moves from higher concentration to lower concentration.

Water moves from cytoplasm to outside hypertonic solution. Types Endosmosis and exosmosis are two types of osmosis shown by cells. Plasmolysis and deplasmolysis are two types of states shown by cells. Plasmolysis occurs due to exosmosis. When water molecules enter a cell via the cell membrane by osmosis, it is known as endosmosis and when the water molecules exit the cell via cell membrane by osmosis, it is known as exosmosis.

Osmosis occurs in almost every type of cells including plant cells. When water exits from a plant cell, cytoplasm contracts and reduces its volume. Cell membrane loses its contact with the cell wall. This state is known as plasmolysis. Plasmolysis occurs due to the exo-osmosis of the cells.
