In brief state what happens when
(a) Dry apricots are left for sometime in pure water and later transferred to sugar solution?
(b) A red blood cell is kept in concentrated saline solution?
(c) The plasma-membrane of a cell breaks down?
(d) When Rheo leaves are boiled in water first and then a drop of sugar syrup is put on it,
(e) Golgi complex are removed

Explanation

(a) Dry apricots when placed in pure water swell due and osmosis (inwatd movement of water) and later when are transferred sugar solution exosmosis (outward movement of water) occurs and they shrink again.
(b) When a Red Blood Cell is placed in concentrated saline solution exosmosis occurs and the RBCs shrink due to excess loss of water.
(c) Breaking of the plasma membrane leads to the scattering of the cell organelles as it forms the basic supporting unit of the cell.
(d) When Rheo leaves are boiled in water first and then a drop of sugar syrup is put on it, osmosis does not occurs, due to the death of the cells of the leaf. This shows that selective premeability is property of living plasma membrane.
(e) Golgi complex helps in the package, stroage and transfer of proteins synthesised by ribosomes. Thus, when ribosomes are removed the cell will not function properly.
