The following figure shows a plant cell immediately after it has been placed in distilled water (A) and a plant cell that has be
en in distilled water for several minutes (B). Determine whether each of the following statements is true or false based on this figure. Two beakers, both filled with a pale blue liquid labeled as Distilled water. A plant cell is submerged in both beakers. The nucleus and some organelles can be seen, along with a large vacuole filled with fluid. The cell in the left beaker is labeled as Plant Cell A, and the cell in the right beaker is labeled as Plant Cell B. The vacuole in Plant Cell B is much more turgid than the vacuole in Plant Cell A, so much so that the outside margin of the cell is distended. Next to the Plant cell A label is the value Psi subscript P equals 0 bar added to the value Psi subscript S equals minus 2 bars. This is shown to give a sum of Psi equals minus 2 bars. Next to the Plant cell B label is the value Psi subscript P equals 2 bars added to the value Psi subscript S equals minus 2 bars. This is shown to give a sum of Psi equals 0 bar.
Plant cell A has lower water potential than cell B.
Plant cell B is isotonic to the fluid in the beaker.
Plant cell A has higher water potential than cell B.
Plant cell B's water potential increased due to an increase in solutes inside the cell.
Plant cell B is at equilibrium with the fluid in the beaker.
Plant cell A is at equilibrium with the fluid in beaker.
Independent assortment states that all alleles are inherited independently of other alleles. This helps diversity because it helps to further the randomization of traits. If traits were always inherited together, as a "package deal", there would naturally be less diversity than the situation that exists.
Arthropoda and molluscs have open circulatory systems - meaning haemolymph (Their equivalent to blood) directly bathes the tissue, and isn't enclosed in blood vessels, as seen in a closed blood system, as in humans for example.
Moisture - There must be sufficient water vapor in the air for a cloud to form. Cooling air - The air temperature must decrease enough for water vapor to condense.
