Venation is the arrangement of veins in lamina of the leaf. Two types of venation are reticulate venation and parallel venation.

(i) Reticulate Venation: When the veins are irregularly distributed to form a channel, it is known as reticulate Venation. Taproots are found in plants which have reticulate venation in their leaves. It can be seen tulsi, coriander (dhania), china rose, hibiscus, mango, etc.

(ii) Parallel Venation: When the veins are parallel and do not form a network, it is known as parallel Venation.Fibrous roots are found in plants which have parallel venation in their leaves. It can be seen in wheat, maize, grass, banana, bamboo, etc.

Cultivation of cotton

Cotton is cultivated in black clayey soil. It needs warm climate. The sowing of cotton crop is done in early spring. Cotton plants are bushy and about 1-2 meters tall. The plants start flowering in about 60 days and give whitish - yellow flowers. The flowers turn reddish in a few days. Flowers slowly grow into spherical walnut-like structures. These are called cotton ball. Fibres of cotton grow on these seeds. After some time green cotton balls turn brown. At maturity, the cotton bolls burst open and the white cotton fibre can be seen.

Ginning: The cotton picked up from the plants has seeds in it. The process of removing cotton seeds from pods is called ginning. Ginning was traditionally done by hand. Now-a-days, machines are used in ginning.

Spinning: The process of making yarn from fibre is called spinning. The raw cotton is supplied to industry in the form of bales.

Weaving: The process of arranging two sets of yarn together to make a fabric is called weaving. The big reels of yarn are called bobbins. These bobbins are used for weaving the cloth. Cloth is woven on looms. After that they bleached and dyed to give a finish.

Knitting: Knitting can be done by hand and machine. Just two yarns are used in knitting, while more than two yarns are used in weaving. Sweater, socks, scarf and caps are knitted from the wool.

Poisonous snakes have either grooved or hollow fangs.

Akshara Chelawat 4 years, 5 months ago

A globe is a spherical model of Earth, of some other celestial body, or of the celestial sphere. Globes serve purposes similar to some maps, but unlike maps, do not distort the surface that they portray except to scale it down. A model globe of Earth is called a terrestrial globe. A model globe of the celestial sphere is called a celestial globe. A globe shows details of its subject. A terrestrial globe shows landmasses and water bodies. It might show nations and major cities and the network of latitude and longitude lines. Some have raised relief to show mountains and other large landforms. A celestial globe shows notable stars, and may also show positions of other prominent astronomical objects. Typically, it will also divide the celestial sphere into constellations. The word globe comes from the Latin word globus, meaning "sphere". Globes have a long history. The first known mention of a globe is from Strabo, describing the Globe of Crates from about 150 BC. The oldest surviving terrestrial globe is the Erdapfel, wrought by Martin Behaim in 1492. The oldest surviving celestial globe sits atop the Farnese Atlas, carved in the 2nd century Roman Empire.

Vitamins and minerals are two of the main types of nutrients that your body needs to survive and stay healthy. Vitamins help your body grow and work the way it should. There are 13 vitamins—vitamins A, C, D, E, K, and the B vitamins (thiamine, riboflavin, niacin, pantothenic acid, biotin, B6, B12, and folate). Vitamins have different jobs—helping you resist infections, keeping your nerves healthy, and helping your body get energy from food or your blood to clot properly. By following the Dietary Guidelines, you will get enough of most of these vitamins from food. Minerals also help your body function. Some minerals, like iodine and fluoride, are only needed in very small quantities. Others, such as calcium, magnesium, and potassium, are needed in larger amounts. As with vitamins, if you eat a varied diet, you will probably get enough of most minerals.

Freezing: Freezing is when a liquid converts into a solid. Example of freezing is turning of water into ice.
Boiling: Boiling is when a liquid converts into a gas. Example of boiling is turning water into water vapour.

Examples of irreversible changes

Burning: When we burn a piece of paper or wood, it turns to ash and smoke. We cannot obtain paper and wood from the ash again.
Cooking: We use heat for cooking, right? Once we cook our eggs, we cannot uncook them. Therefore, cooking is an irreversible change.
Rusting of iron: You must have seen rusting of iron. When water vapour (humidity) comes in contact with the iron, they react. Therefore, iron rusts and once this happens, we cannot reverse it.
