• Genes are functional units of heredity that determine the characters of organisms,
• Diffusion is the process of passage of fluid from a region of high concentration to a region of low concentration. It plays an important role in the gaseous exchange between the cells as well as the cell and its external environment. Water also obeys the law of diffusion.
• The passage of water from a region of higher water concentration to a region of lower water concentration through a semi-permeable membrane is called osmosis. The movement of water across the plasma membrane is affected by the amount of substance dissolved in water. 
• Plasmolysis refers to the contraction of protoplast as a result of the loss of water from the cell.

The shrinkage of cytoplasm occurs due to exo-osmosis in a hypertonic medium. A hypertonic solution is one that has a lesser concentration of water as compared to that inside the cell. During the process, there is a higher external osmotic pressure and a net flow of water from the cell.

Q.39: Following are a few definitions of osmosis read carefully and select the correct definition.
(a) Movement of solvent molecules from its higher concentration to lower concentration
(b) Movement of solvent molecules from higher concentration to lower concentration of solution through a permeable membrane
(c) Movement of solute molecules from lower concentration to higher concentration of solution through a semipermeable membrane

(d) Movement of water molecules from a region of higher concentration to a region of lower concentration through a semipermeable membrane

Correct Answer is Option (d)
Osmosis is the passive movement of water or any other solvent molecules from a region of higher water concentration to a region of lower water concentration through a semipermeable membrane.

Read the text carefully and answer the questions:
Air is a homogeneous mixture and can be separated into its components by fractional distillation. The air is compressed by increasing the pressure and is then cooled by decreasing the temperature to get liquid air. This liquid air is allowed to warm-up slowly in a fractional distillation column, where gases get separated at different heights depending upon their boiling points. The properties that can be observed and specified like colour, hardness, rigidity, etc. are the physical properties. The interconversion of states is a physical change because these changes occur without a change in composition and no change in the chemical nature of the substance.

Read the text carefully and answer the questions:
Leeuwenhoek discovered the free-living cells in pond water for the first time. Robert Brown discovered the nucleus in the cell. A single cell may constitute a whole organism as in Amoeba. These organisms are called unicellular organisms. On the other hand, many cells group together in a single body and assume different functions in it to form various body parts in multicellular organisms. The shape and size of cells are related to the specific function they perform. Each living cell has the capacity to perform certain basic functions that are characteristic of all living forms. Each kind of cell organelle performs a special function, such as making new material in the cell, clearing up the waste material from the cell and so on.
