They are components found in plants
The major carbohydrates found in cell walls are cellulose, hemicellulose and pectin. The cellulose microfibrils are bonded through hemicellulosic tethers to give the cellulose-hemicellulose network, that is found in the pectin matrix.
Cell membrane are majorly made up of phospholipids, glycolipids, proteins, and cholesterol. The lipid found mostly though our the membrane are the phospholipids.
Enzymes are biological molecules that are protein in nature and accelerate the rate of the chemical reactions that occurs within cells.
4. Nucleic Acid
Nucleic acids aid major activities in the cell by serving as the repository of the genetic materials needed for the transfer of inherited characteristics from parents to offspring and from an individual cell to another cell
A.They're components found in plants.
answer: option (a) is the correct answer.
phospholipids come under the class of lipids and these are the major component of all cell membranes.
whereas plasma is the major component of blood fluids. blood fluids contains high amount of water along with proteins, ions, nutrients and wastes mixed together.
the body can make phospholipids. they’re components found in plants and also found in animals products.
thus, out of the given options they’re major components of cell membranes, blood fluids, and body fluids is the one statement about phospholipids which is least accurate because phospholipds are the major component of cell membranes but not the major component of blood fluids.
B.The body can make them.
Although phospholipids are produced by the body, this phrase is very inaccurate because it does not explain where they are produced, why they are produced, or what body produces them. Although all other options are lacking in detail, we can say that the letter B is the most inaccurate among them.
Phospholipids are the lipids associated with phosphoric acid. They are amphipathic molecules, ie one region (head) is hydrophilic, and another region (tail) is hydrophobic. They have a structure very similar to triglycerides and are important constituents of the plasma membrane of all cells.

major structural component of the cell wall is carbohydrates. Major component of cell membranes is lipids. Proteins speed up chemical reactions in the cell. Nucleic acids are responsible for inheritance.
Biological macromolecules are large molecules in the cell formed by the covalent linkage of smaller molecules. The four major macromolecules found in living cells are carbohydrates, lipids, proteins and nucleic acids.
Out of these 4 macromolecules, 3 are able to form polymers. A polymer is made up of many similar building blocks called monomers which are joined by commenting bonds. These macromolecules that form polymers are carbohydrates, proteins and nucleic acids. Lipids are not able to form polymers.
Carbohydrates: these are made up of sugars such as glucose, sucrose, fructose. The carbohydrate is the major structural component of the cell wall. Cellulose for example, is found in plants and is the major component of plant cell wall. Chitin is also a structural component of the exoskeletons of arthropods. Cellulose and chitin are polymers of carbohydrates.
Lipids: they consist majorly of hydrocarbons, hence separate easily from water. Lipids are made up of fatty acids and glycerol. They act as major components of the cell membrane which helps in insulation and act as barrier between the cell and its external environment.
Protein: proteins are made up of amino acids. All enzymes in the body are proteins and they function as catalysts speeding up chemical reactions in the body without being consumed by the reaction.
Nucleic acids: in most living cells, two types of nucleic acids exist, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). They are made up of nucleotides. Nucleic acids are responsible for the passage of inheritance genes or traits from parents to offspring. During replication, the double stranded DNA helix opens up so that new complementary strands are made. At the end, two new identical helices are made and each given to the new daughter cells.

The correct answer is D carbohydrates are a source of energy .
Carbohydrates can be defined as Polyhydroxy Aldehydes or Polyhydroxy ketones.Carbohydrates are major source of energy in our body.
Carbohydrate such as glucose is broken down to through glycolysis, TCA cycle and oxidative phosphorylation collectively called aerobic respiration to generate carbon di oxide,H2O and adenosine Tri Phosphate or ATP.
1 molecule of ATP is broken down to generate -30.5 kj/mole energy which is used as free energy by the cell to carry out various cellular and physiological process such as gluconeogenesis,Muscle contraction etc.
