here case-2(b) = Pq (((((--- minus))) + pg(x+y) coz height of M - fluid in Q-side less than the. P-side
No dear, it's not like that. +ve & -ve sign is taken with reference to datum level and applied only in the height of both the fluid w.r.t. datum level. It is nothing to do with the pressure at any point. Pressure at Q(Pq) is taken with prefix +ve(+Pq) (if you are using the same method what I did in this lecture i.e. LHS=RHS) otherwise Pq will be used with prefix -ve (-Pq)(if you are keeping all the pressure in the left hand side and keeping RHS equals to 0 to keep the system in equilibrium). But keep it in mind Pq's value can be +ve or -ve because it measures the gauge pressure.
Thanks a lot. I understood it better than in class.!!!!!!

  3. Types Of Solution Hypotonic solution (hypo-below) Isotonic solution (iso-equal) Hypertonic solution (hyper = above)

  4. Isotonic Solution If the medium has exactly the same water concentration as the cell, there will be no net movement of water across the cell membrane. Water crosses the cell membrane in both directions, but the movement going in is the same as the amount of going out. The cell will stay the same size.

  5. Hypotonic Solution If the medium surrounding the cell has a higher water concentration than the cell The cell will gain water by osmosis. The cell is likely to swell up.

  6. Hypertonic Solution If the medium has a lower concentration of water than the cell The cell will lose water by osmosis. The cell will shrink.

  7. Hypotonic solution Isotonic solution Hypertonic solution (a) Animal cell H20 H20 H20 H20 Lysed Normal Shriveled (b) PlantH2O H20 H20 cell Turgid (normal) Flaccid Plasmolyzed

  8. Plasmolysis When a living plant cell loses water through osmosis there is shrinkage contraction of the contents of the cell away from the cell wall straction of theH,0 0 2
