Rotation is the act of raising the nose of an aircraft (by pulling back slightly on the control yoke or stick) during the take-off roll, so that it leaves the runway. Rotation allows for a precise, positive departure from the runway.
Crenation is the loss of water from an animal cell due to osmosis. Lysis is the rupture of the cell wall due to too much water moving into an animal cell due to osmosis. Both â¦crenation and lysis have drastic effects on the animal cell.
Crenation Versus Plasmolysis. While crenation occurs in animals cells, cells that have a cell wall cannot shrink and change shape when placed in a hypertonic solution. Plant and bacterial cells instead undergo plasmolysis. In plasmolysis, water leaves the cytoplasm, but the cell wall does not collapse.
