Question

Resin and Turpentine is obtained from
A. Pteridophytes
B. Gymnosperms (Pinus) wood
C. Angiosperms
D. Angiosperms (Neem) flower.

Answer 1

Resins is an organic substance that is fusible and flammable. They are the plant exudates that make the wood resistant to decay. However, the turpentine is a liquid obtained by distillation of resins. Coniferous trees produce both resins and turpentines.

Complete answer:
To answer this question, first, we need to know about Resin and Turpentine. Resin is a solid or highly viscous substance of plant or synthetic origin that is typically convertible into polymers. Resins are a common combination of organic components. Plants release resins for their safety benefits in the result of injury. The resin saves the plant from pathogens and insects.
Turpentine is the extract obtained from coniferous trees, specifically those which belong to the genus Pinus. Turpentines are not completely fluid material; it contains resins soluble in a volatile oil.

Now, let us find the solution from the option.
Turpentine is a semi-fluid produced by the purification process of resin from living trees, like pines. It is utilized as a solvent and also as an origin of components for organic production.
Pinus longifolia is a kind of pine tree from which turpentine is obtained. This belongs to the Pinaceae family of gymnosperms. Resin, in the most specific meaning of the term, is a hydrocarbon secretion of many plants, particularly coniferous trees. It is distinct from other liquid compounds found inside plants or exuded by plants, such as sap, latex, or mucilage. It is also obtained from palm plants of Gymnosperms.

Thus, the correct option is B. i.e. Gymnosperms.

Note: Almost all plant resins consist of terpenes. Some resins additionally consist of a maximum amount of resin acids. The word turpentine mainly mentioned the all oleoresinous extraction, now it mentions its volatile turpentine factor only, which has many uses in visual art and industry.
