 17.What are carbohydrates? Why are they called hydrated carbons?

answers: 


Carbohydrate is a group of organic compounds occurring in living tissues and foods in the form of starch, cellulose, and sugars. The ratio of oxygen and hydrogen in carbohydrates is the same as in water i.e. 2:1. It typically breaks down in the animal body to release energy.

What are Carbohydrates?

Cn(H2O)n is the generic formula for all carbohydrates. This formula is only valid for simple sugars, which are made up of the same amount of carbon and water.

Originally the term carbohydrate was used to describe compounds that were literally “carbohydrates,” because they had the empirical formula CH2O. Carbohydrates have been classified in recent years on the basis of carbohydrate structures, not their formulae. Such aldehydes and ketones are now known as polyhydroxy. Cellulose, starch, and glycogen are among the compounds that belong to this family.


Carbohydrates are called hydrates of carbon because of their empirical formulae.

Explanation:

•Earlier carbohydrates were called hydrates of carbon because the ratio of carbon, hydrogen and oxygen in its simplest form is 1:2:1.

• Only compounds of hydrated carbon were counted under carbohydrates.

•C:H:O ratio is 1:2:1 which indicates that carbohydrates consist of Carbon and H:O in the ratio of 2:1 which is the formulae of water.

  5. Tabulate the unique and common features for both plant and animal cells.  answer : Difference Between Plant cell and Animal cell The cell is the fundamental unit of life. All the life activities are carried out by cells. The organisms can be classified based on the number of cells present in them. Unicellular organisms are single-celled, while multicellular organisms have a large number of cells. Unicellular organisms are believed to be one of the earliest forms of life on earth. Eventually, more complex multicellular organisms evolved from these unicellular life forms over the aeons. Multicellular organisms have specialized cells with complicated cell organelles, which unicellular organisms typically lack. In an ecosystem, plants have the role of producers, while animals have taken the role of consumers. Hence, their daily activities and functions vary, and so does their cell structure. Cell structure and organelles vary in plants and animals, and are primarily clas...

  2.Compare the functions of starch and glycogen with a note about their different linkages. answers:  Difference between Starch, and Glycogen The table below shows the main differences between starch, cellulose and glycogen. Starch Glycogen It is a polymer of 𝜶-glucose subunits It is a polymer of 𝜶-glucose subunits It contains two types of polymers, amylose (unbranched and coiled) and amylopectin (branched) It is highly branched and similar to amylopectin The 𝜶-glucose subunits are joined by 1,4 glycosidic bonds in amylose and 1,4 and 1,6 glycosidic bonds in amylopectin The 𝜶-glucose subunits are joined by 1,4 and 1,6 glycosidic bonds Amylose is unbranched and amylopectin is branched It is highly branched It is the main storage carbohydrate in plants It is the main storage carbohydrate in animals and fungi Structure of Starch Starch is the main storage carbohydrate of plants. It is made up of 𝜶-glucose subunits. It contains two types of polymers, amylose and amylopectin....

1. Elaborate on the diversity of the root and shoot system of plants answer: Introduction Plants are one of the most important living organisms on earth. They have huge benefits for both humans and animals. A plant is made up of numerous parts. Distinct parts serve different purposes. The shoot system refers to the portion of the plant that protrudes above ground level, whereas the root system refers to the portion buried beneath the soil. The essential parts of a plant are: Roots Stem Leaves Flowers Fruits The study of plant organ tissue and cellular structure is known as plant anatomy. Cells serve as the fundamental building block of plants. Cells are organised into tissues, which are then organised into organs. Plant organs differ from one another in terms of their internal structure. The monocots and dicots are also observed to have diverse anatomical structures within angiosperms. Internal structures also exhibit environmental adaptations. Anatomy of Root All vascular plants have ...
