|
| 1410. |
Question : A cell is placed in a solution swelled up. What kind of solution is it? Why does it happen? |
| Answer» SOLUTION :When a cell swells up, it means that the water from outer medium enters the cell by crossing the plasma MEMBRANE. This happens due to lower CONCENTRATION of water in the cell sap as COMPARED to the outer solution. As water concentration in outer medium is more, it moves through semi-permeable plasma membrane, in the cell. This is endosmosis. This shows that the solution in which cell is KEPT is hypotonicas compared to the concentration of cell sap. | |

Question :1. Explain hydroponics and give its importance. |
|
Answer» Solution :HYDROPONICS is the method of growing plants without soil,using mineral nutrient solutions in water. The containers are made of glass, METAL or plastic.They range in size from small pots for individual plants to huge tank for large SCALE growing.It was demonstrated by a German Botanist Julius Von Sachs in 1980. Hydroponics issuccessfully employed for the commercial production of seedless cucumber and tomato.Plants are suspended withtheir roots submerged in water that contain plant nutrients.The roots absorb water and nutrients, but do not perform the anchoring function.Therefore, the plants must be mechanically SUPPORTED from above. Importance of hydroponics (i) Conservation of water and nutrients. (ii)Controlled plant growth. (iii) In deserts and Arctic regions hydroponics can be effective alternative method. |

|
Answer» Solution :HYDROPONICS was demonstrated by a German Botanist Julius Von SACHS in 1980 Advantages Crops can be grown in places where the land is limited, doesn.t EXIST,or is heavily contaminated.The climate - TEMPERATURE, humidity, light INTENSIFICATION, the composition of the air can be monitored. Conservation of water and nutrients. Controlled plant growth. No intrusion by weeds. Fewer pests & diseases Minimal use of insecticide or herbicides.
