Question

Which of the following can be obtained from plants?
A.Starch
B.Sugar
C.Carbohydrates
D.All of these

Answer 1

Hint: There are a number of derived and naturally sourced products that are obtained from plants that are useful to us and are used in our day to day life. These compounds have a variety of different iterations but are often classified under the same respective categories.

Complete Step-by-Step Answer:
Before we move forward with the solution of this question, let us first understand some important basic concepts.
1.Starch: the most basic explanation of starch can be understood as the excessive glucose that is produced by the plant which would not be used immediately. It acts as a reserve food supply. It is a polysaccharide compound which consists of glucose monomers joined in \[\alpha \] 1,4 linkages. The general molecular formula of starch molecules can be given as \[{({C_6}{H_{10}}{O_5})_n}\]
2.Sugar: sugar is the basic food unit used by a plant. It is obtained from the metabolic activities carried out in the plant. There are different types of sugar obtained from plants like glucose, sucrose and fructose. They differ in their molecular structures, as well the region of the plant from which it is obtained. The chemical formula for sugar can be given as \[{C_6}{H_{12}}{O_6}\] .
3.Carbohydrates: carbohydrates are also obtained from plants. Derivatives of carbohydrates are widely used in our diets to complete a balanced meal. The general molecular structure of carbohydrates can be given as \[{C_m}{({H_2}O)_n}\] .
Hence, all the compounds given in the options are obtained from plants.
Hence, Option D is the correct option

Note: Carbohydrates is most common in biochemistry, where it is a synonym of saccharide, a group that includes sugars, starch, and cellulose. Now these saccharides are divided into 4 major groups: monosaccharide, disaccharide, polysaccharide and oligosaccharide.
