👉 Root fluid, also known as protoplasmic fluid or cytosolic fluid, is the gel-like substance that fills the space within plant cells, excluding the cell wall. It is primarily composed of water, dissolved salts, sugars, and various organic molecules, including proteins, nucleic acids, and enzymes. This fluid is crucial for maintaining cell turgor pressure, nutrient transport, and cellular metabolism, providing a medium for biochemical reactions to occur efficiently. Unlike animal cells, plant cells have a rigid cell wall, and their root fluid plays a vital role in sustaining the cell's internal environment and facilitating communication between cells.
