Leaves are the most significant part of plants that plays the most important role in producing food.
The food production process in plants is called photosynthesis.
In this process, the green plants make the food by using water and carbon-dioxide along with chlorophyll and sunlight to produce both oxygen and food.

| They are large foreign molecules. | They are self molecules and circulate in body fluids. |
| Chemically they are either proteins or polysaccharides. | Chemically they are proteins. |
| Their entry into the body stimulates the formation of antibodies. | They are produced in response to antigens. |
| An antigen may occur on the surface of a microbe or as a free molecule. | Antibody occurs on the surface of a plasma cell and also in body fluids. |
| An Antigen binds to a macrophage to reach a helper T-cell to initiate the immune response. | Antibody directly joins an antigen to destroy the latter. |

The Indian Constitution provides for the independence of the judiciary. It means that other branches of the State such as the legislature and the executive cannot interfere in the work of the judiciary. The courts are not under the government and do not act on their behalf. The courts ensure that there is no misuse of power of the legislature and the executive. Anyone can approach the courts if they find that their Fundamental Rights have been violated. Thus, the courts are not influenced by anyone, not even by the rich and powerful people.

Sound is a form of energy that travels in the form of vibrations through the air or any another medium.
Certain sounds such as thunder, the rattling of wheels on a rough road, or a large number of people talking at the same time inside a room are unpleasant to hear. These sounds are called noise and produced by irregular and non-periodic vibrations.

The various shapes of the bright side of the moon as seen during a month are called the phases of moon. The day on which the whole disc of the moon is visible is known as the full moon day. Thereafter, every night, the size of the bright part of the moon appears to become thinner and thinner. On the fifteenth day, the moon is not visible which is called as the new moon day. The next day, only a small portion of the moon appears in the sky. This is known as the crescent moon. Then again the moon grows larger every day. On the fifteenth day once again the full view of the moon is visible.

1. Places a bar over every pair of digits from right to left (<—). Here, single digit 7 is left, so put a bar over 7.
2. Take the digit 7. Find the greatest number whose square is 7 or less than 7. Such a number is 2. Write 2 at the top in the quotient and also 2 in the divisor. Subtract 22 i.e. 4 from 7. The remainder is 3.
3. Bring down the pair of digits under the next bar (i.e. 85) to the right of the remainder. So new dividend is 385.
4. Double the quotient (i.e. 2) to get 4 and enter it with a blank on its right at the place of new divisor.
5. Find the largest possible digit to fill the blank which will also become the digit in the quotient, such that when the new divisor is multiplied by this digit in the quotient the product is less than or equal to the dividend. In this case 48 x 8 = 384, so we choose the new digit as 8. Place 384 under Subtract and get the remainder 1.
6. Bring down the pair of digits under the new bar (i.e. 68) to the right of the remainder. So new dividend is 168.
7. Double the quotient (i.e. 28) to get 56 and enter it with a blank on its right at the place of new divisor.
8. Since no non-zero digit can fill the blank such that when the new divisor is multiplied by this new digit in the quotient so that the product is less than or equal to the dividend. Therefore, put 0 at blank in the divisor to get 560 and also put 0 in the quotient to get 280.
9. Bring down the pair of digits under the next bar (i.e. 09) to the right of 168 to get 16809 as the new dividend. Now find the largest possible digit to be put at the right of the divisor 560 which will also become the new digit in the quotient, such that when the new divisor is multiplied by the new digit in the quotient the product is less than or equal to dividend.
In this case 5603 x 3 = 16809, so we choose new digit as 3. Place 16809 under the dividend 16809 and get remainder 0.
