Ap Biology Lab 1 Questions

AP Biology Lab 1 Ross Lordo Introduction Questions 1. The solute potential would be -2. 48. If the concentration inside the cell is . 15 M, then would diffusion out of the cell and into the solution of . 1 M. This is receivable to pee potential and the tendency for water to move from areas of high water potential to low water potential. 2. The turgor pressure must be refer to the water potential if at that place is no net diffusion.The cell and environs have come acrossed equilibrium and the movement of water is equal on both(prenominal) sides. Getting Started 1. Kinetic life force is the aught an object possesses due to its motion. The remnant between kinetic force and potential energy is the kinetic energy is the energy of an object that is already in motion and potential energy is the energy possessed by an object at rest. Potential energy is stored energy, while kinetic energy is energy being exerted. 2.Temperature can collide with the evaluate of diffusion. If the t emperature is colder, the rate of diffusion is much slower as a endpoint of all particles becoming closer to attracther. If the temperature is warmer, there is much to a greater extent energy present and therefore allows for the diffusion to polish off place at a fast rate. The quad a molecule needs to give-up the ghost a crisscross the membrane can also affect the rate of diffusion. If the distance across the membrane is large, then the rate of diffusion volition be much slower and vise versa. 3.A high temperature can speed up the diffusion process by providing more energy for the molecules and also for eliminating in double bonds in the phospholipid membrane. A low temperature leave decline the rate of diffusion, as the particles will have less energy. The distance travelled will also affect diffusion rates. The longer the distance, the slower the diffusion is press release to take place. The shorter the distance, the quicker the rate of diffusion 4. Gradients offer a pass for molecules to go in and out of the cell.Many molecules are to big to fit by dint of the semipermeable phospholipid membrane and these gradients allow these large molecules to be able to cross through the cell. 5. Most cells are small be driving force diffusion can take place at a quicker rate. The convolutions allow for more stead to be able to be used in order to get molecules across the membrane. These small cells allow for materials to quickly be able to reach the cell membrane and get in or out of the cell, without having to arouse a long journey from an inside part of the cell. . Water will move out of the cell. The high water potential means there is little solute in the cell and more in the outside environment. In order to quietus these concentrations, water moves out of the cell and creates equilibrium with the environment. 7. If saltwater is applied to a full treatment, the plant would shrivel up and die. This is a result of the water moving out of the cells in or der to try to balance the concentration of solute compared to inside the cell.The water movement out of the cell would cause the cell to shrink and the lack of water would eventually cause the plant to die. 8. A plant can control its turgor pressure through its substitution vacuole and cell wall. If a great amount of water is inside the cell, the substitution vacuole will take in slightly of the water to take some of the pressure of the cell wall. The cell wall can also slide by water from making its way into the cell. The would cause the cell to keep expanding, only slowly eliminate its excess water.
