Question

Sap of which plant is considered as a good substitute for diesel oil
A. Euphorbia sp
B. Copaliera langsdorffii
C. Calotropis procera
D. Manihot glaziovii

Answer 1

Hint: Sap is a fluid carried by a plant's xylem cells or phloem sieve tube components. Water and nutrients are transported throughout the plant by these cells. Sap is not the same as latex, resin, or cell sap; it is a distinct substance that is created separately and has various components and purposes.

Complete answer:
The main component of xylem sap is a fluid solution of hormones, minerals, and other nutrients. The movement of sap in the xylem is defined by movement from the roots to the leaves. Sugars, hormones, and mineral components dissolved in water make up the majority of phloem sap. It flows from the point at which carbs are created or stored (the sugar source) to the point at which they are consumed (sugar sinks).
The sap is often taken from the sugar maple, Acer saccharum. Maple syrup is manufactured from decreased sugar maple xylem sap. The early spring sap of birch tree is commonly harvested for human use in several regions; the fluid can be consumed fresh or fermented and contains xylitol.
Palm syrup is made from a variety of palm tree sap. The Canary Island date palm is used to manufacture miel de palma in the Canary Islands, whereas the Chilean wine palm is used in Chile.
The diesel tree and kerosene tree are two names for the tropical rainforest tree Copaifera langsdorffii. In its wood and leaves, it produces a considerable amount of terpene hydrocarbons. Each year, a single tree can produce 30 to 53 litres of hydrocarbons.

Note: Many insects in the Hemiptera (half-winged) order feed exclusively on phloem sap and make it their principal source of nutrition. Despite the fact that phloem sap is "nutrient-dense relative to many other plant products and generally free of toxins and feeding deterrents," it is "consumed as the major or exclusive diet by a very limited range of animals."
