Explanation / Answer
1. Nutrient transport is a process by which nutrients gets tranported within the body of an organism. There are usually two types of nutrient transport process available: Active transport and Passive transport.
Similarities:
Differences:
2. Tonicity is defined as the ability of an extracellular solution to make water move into or out of a cell by osmosis. The tonicity of a solution is related to its osmolarity, which is the total concentration of all solutes in the solution. A solution with low osmolarity has fewer solute particles per liter of solution, while a solution with high osmolarity has more solute particles per liter of solution.
According to tonicity, three type sof solutions exist: Hypertonic, Isotonic and hypotonic. If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, the relative concentrations of solute and water are equal on both sides of the membrane. There is no net water movement, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.
Active transport Passive Transport Active Transport uses ATP to pump molecules against the concentration gradient. Movement of molecules down the concentration gradient. Transport occurs from a low concentration of solute to high concentration of solute It goes from high to low concentration, in order to maintain equilibrium in the cells Example: phagocytosis, pinocytosis, sodium/potassium pump, Example: diffusion, osmosis, and facilitated diffusion.Related Questions
