Cells are the basic, fundamental unit of life. So, if we were to break apart an organism to the cellular level, the smallest independent component that we would find would be the cell.

Collect a few small plastic or rubber caps of discarded bottles and clean them. Pour one teaspoon of lemon juice or vinegar in one cap. Bring your tester over this cap and let the ends of the tester dip into lemon juice or vinegar. Take care that the ends are not more than 1 cm apart but at the same time do not touch each other. When an electric current is passed through vinegar or lemon juice, the bulb glows very dimly which indicates that though vinegar and lemon juice conduct electricity but they are weak conductors of electricity.

The transport of food from the leaves to other parts of the plant is called translocation. Phloem tissue transports the food from the leaves to the other parts of the plant. The movement of food in phloem takes place by utilising energy. The sugar made in the leaves is loaded into the sieve tubes of phloem by using ATP. Water enters the sieve tube containing sugar which causes high pressure and pushes the food to all the parts of the plant having low pressure. This is how the food is transported according to the needs of the plant.

Iron when reacted with both water and oxygen which present in air (moist air), corrodes. Its silvery colour changes to a reddish-brown, because hydrated oxides are formed which is commonly called as rust.
The chemical formula for rust is Fe2O3.nH2O.

- A rainbow is an arch of seven colours and is produced by the dispersion of the Sun’s light by tiny raindrops present in the atmosphere.
- The observer receives only one colour from the raindrop at a time.
- The red rays from the drops make a certain angle with the eye line joining the Sun and the observer.
- So, all water drops which appear red will make the same angle with the line of vision.
- Hence, they will appear in the form of an arc of a circle with its centre on the eye line.
- The other colours also appear in a similar manner.
- Red rays make an angle of 42.8° with the line of vision and is seen on the outer edge of the rainbow.
- Violet rays make an angle of 40.8° with the line of vision and is seen on the inner edge of the rainbow.
- Thus, the rainbow appears in the form of a bow or a semi circle

The cells of plants and animals need various substances to carry out important metabolic activities. Further, many waste products are created during these metabolic activities. Transport of materials is necessary to supply various substances and to remove waste products.

| Xylem | Phloem |
| Xylem tissues are tubular shaped structure, with the absence of cross walls. This tissue resembles the shape of a star. | Phloem tissues are elongated, tubular shaped structures that include thin sieve tubes with walls. |
| Xylem occupies the centre of the vascular bundle. | Phloem is located on the outer side of the vascular bundle. |
| Xylem fibres are smaller. | Phloem fibres are larger. |
| They are present in leaves, stems, and roots. | They are present in leaves, roots, stems but transports and grow in fruits seeds and roots. |
| These tissues move in a Unidirectional. (only in one direction – upward direction) | These tissues move in a Bidirectional. (both ways – up and down) |
| They live with hollow dead cells. | They live with cytoplasm without the nucleus. |
| The total amount of xylem tissue is more. | The total amount of phloem tissue is less. |

AEROBIC RESPIRATION: Aerobic respiration takes place in the presence of oxygen. Carbon dioxide and water are the end products of aerobic respiration. Aerobic respiration happens in most of the organisms.
Glucose (Presence of oxygen) → Carbon dioxide + Water + Energy
ANAEROBIC RESPIRATION: Anaerobic respiration takes place in the absence of oxygen. Anaerobic respiration usually happens in most of the microbes. Alcohol and carbon dioxide are formed at the end of anaerobic respiration. In some cases, lactic acid is formed at the end of anaerobic respiration.
Glucose (absence of oxygen) → Alcohol + Carbon dioxide + Energy
Glucose (absence of oxygen) → Lactic acid + Energy

If you use a straw to blow air into a glass of water, you can make bubbles. The bubbles tend to be small, and they disappear quickly. A drinking straw is used by creating a suction with your mouth. Actually this causes a decrease in air pressure on the inside of the straw. Since the atmospheric pressure is greater on the outside of the straw, liquid is forced into and up the straw. ... The vacuum itself is not what causes the sucking.
