• In this type of dialysis, the dialysis fluid is pumped for a time into the peritoneal cavity which is space around gut. This cavity is lined by peritoneum. Peritoneum contains blood vessels. 
• Important class 10 biology chapter 2 important short questions for all students of Punjab  Textbook Board.
• When we place dialysis fluid in peritoneal cavity, waste materials form peritoneal blood vessels diffuse into the, dialysis fluid, which is then drained out: This type of dialysis can be performed at home, but must be done every day.

• How plants remove extra Carbon Dioxide, Oxygen and Water.
• Osmotic Adjustments in Plants: On the basis of the available amount of water and salts, plants are divided into three groups.
• Important class 10 biology chapter 2 important diagrams for all students of Punjab  Textbook Board.
• Hydrophytes are the plants which live completely or partially submerged in freshwater. Such plants do not face the problem of water shortage. They have developed mechanisms for the removal of extra water from their cells.
• Important class 10 biology chapter 2 important questions with answers pdf for all students of Punjab  Textbook Board.
•  Hydrophytes have broad leaves with a large number of stomata on their upper surfaces. This characteristic helps them to remove the extra amount of water. The most common example of such plants is water lily.

• Xerophytes live in dry environments. They possess thick, waxy cuticle over their epidermis to reduce water loss from internal tissues. They have less number of stomata to reduce the rate of transpiration. 
• Important class 10 biology chapter 2 short questions and answers pdf for all students of Punjab  Textbook Board.
• Such plants have deep roots to absorb maximum water from soil. Some xerophytes have special parenchyma cells in stems or roots in which they store large quantities of water. This makes their stems or roots wet and juicy, called succulent organs. Cacti (Singular Cactus) are the common examples of such plants.

• Halophytes live in sea waters and are adapted to salty environments. Salts enter in the bodies of such plants due to their higher concentration in sea water.

• On the other hand, water tends to move out of their cells into the hypertonic sea water. When salts enter into cells, plants carry out active transport to move and hold large amount of salts in vacuoles.
• Important class 10th biology chapter 2 short notes for all students of Punjab  Textbook Board.
• Salts are not allowed to move out through the semi- permeable membranes of vacuoles. So the sap of vacuoles remains even more hypertonic than sea water. In this way, water does not move out of cells. Many sea grasses are included in this group of plants.
