Question

Hevea is a source of
(a)Soft fibre
(b)Strong fibre
(c)Soft drink
(d)Best rubber

Answer 1

Hint: Hevea is a flowering plant that belongs to the spurge family e and is the most economically important member of the genus Hevea as the milky late extracted from it is the primary source for natural rubber.

Complete answer:
Hevea is a source of the best rubber. It produces the white or yellow latex in the latex vessels present in the bark which is outside the phloem. These vessels form an angle of about 30 degrees in a right-handed helix and can grow as high as 45 feet. The tree of rubber can reach a height of up to 140 feet or 43 meters. These trees grow more slowly when they are tapped for latex and are generally cut down after 30 years as the latest production declines as the tree gets aged. On becoming aged it is no longer economically productive. It takes between 7 and 10 years to deliver the first harvest of the natural rubber. The latest is collected in the small buckets as the harvester makes incisions across the latest vessels.

Additional Information: Soft fibre: Soft fibres are also known as bast fibres and this around the stem of certain dicotyledonous plants. The conductive cells of the phloem are supported by the best fibres and it provides strength to the stem. Flax, hemp or ramie are some of the economically important fibres that are obtained from The herbs cultivated in agriculture.
Strong fibre: The song is fibre is the nylon which is a thermoplastic silky material and can be melt-processed into fibres, films or shapes. It is used in the bristled toothbrush and was first sold commercially in 1940.
Soft drink: It is a drink that contains carbonated water and a sweetener that is rich in sugar, high fructose and a sugar substitute. It also contains caffeine, preservatives, and other ingredients with colourings. Soft drinks are served chilled with ice cubes at room temperature and are available in many container formats which include cans, plastic bottles, and glass bottles.
So, the correct answer is 'Best rubber'.

Note: Hevea trees produce milky coloured latex sap which is used once it matures to an age of about 6-year-old. They can grow up to 100 feet tall in the wild and usually grow up to a height of 10 feet. On the ripening of the trees, it undergoes reproduction and burst open. It grows best in the bright sunlight and is suited for the wet and hot climate of the tropical rainforest.
