Question

In brief, state what happens when
(a) Dry apricots are left for some time in pure water and later transferred to a sugar solution
(b) A red blood cell is kept in a 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 is removed

Answer 1

a) Exosmosis:

1. The plum genus includes fleshy fruits called apricots.
2. Dry apricots kept in water will swell as a result of the incoming water through the endosmosis process.
3. They lose water by exosmosis when placed in a strong sugar solution, though.
4. When a cell is submerged in a hypertonic solution, exosmosis occurs, which is the flow of water outside the cells.
5. The outer water flow causes the cell to become flaccid.
6. Water is moved via a permeable membrane during the osmosis process from a high water potential to lower water potential.

b) RBC:

1. The most prevalent type of blood cell is the red blood cell, also known as red cells, red blood corpuscles, haematids, erythroid cells, or erythrocytes.
2. The concentrated saline solution is used to preserve red blood cells.
3. Exosmosis will cause it to shrink and lose water.

c) Plasma Membrane:

1. The membrane that divides the interior of the cell from the external environment is known as the plasma membrane, sometimes known as the cell membrane, and is present in all cells.
2. A cell wall is affixed to the plasma membrane on the exterior of bacterial and plant cells.

• The cell's shapes will change.
• That cell's cell components could sustain harm.
• The cells might be exposed to harmful chemicals.
• The cells may release helpful chemicals.

d) Rheo's Leaves:

1. The oyster plant/boat of Moses is another name for the Rheo leaf.
2. It is a robust perennial herbaceous plant with a somewhat mushy texture.
3. The stem is thick and unbranched, with a dark green upper surface and a purple lower surface.
4. The cells in the plasma membrane are destroyed when Rheo leaves are boiled in water.
5. Plasmolysis won't happen when a drop of sugar syrup is applied to it since only living cells can osmotically absorb water; dead cells cannot.
6. Plant cells subjected to hyperosmotic stress frequently exhibit plasmolysis as a reaction.
7. The live protoplast violently separates from the cell wall as a result of the loss of turgor.

e) The Golgi Complex:

1. A group of tiny, flat sacs that are stacked one above the other in the cytoplasm of the cell (gel-like fluid).
2. The Golgi complex prepares proteins and lipid (fat) molecules for usage both inside and outside of the cell by the Golgi complex.
3. A cell organelle is the Golgi complex.

If the cell's Golgi apparatus is taken out:

1. The cell's secretion process will be interrupted.
2. Packaging and shipping of useful goods will come to an end.
3. Broken membranes, lysosomes, plasma membranes, etc., won't form or be repaired.
4. Dead cell components won't be eliminated.
