CHAPTER I INTRODUCTION Tomato is a very significant ingredient to Filipino cuisines thus it is produced widely in the Philippines. Tomatoes rank second to aubergine in the aspect of food production. Dejectedly‚ the production of fruits in the Philippines is below average level due to the damages caused by various insects and viruses. The infections of these pests cause a yield reduction of 50% to 100% which threatens the livelihood of the small scale farmers of tomatoes. Aside from pests‚ the

is mostly unicellular and some organisms that form groups or filaments. • These organisms are the simplest prokaryotic cell structures. • The Monera cell structure lacks nuclei and many other cell organelles. • They have a cell wall made of polysaccharides with polypeptide cross links with a chemical called peptidoglycan. • They lack enclosed sub-cellular organelles like mitochondria and only have ribosomes. • The genetic material DNA is contained in the cytoplasm called nucleoid. • Many bacterial

necessary for the body to function properly because they provide the fuel that burns to produce energy. Carbohydrates come in the class of either a monosaccharide‚ disaccharide‚ or polysaccharide. Monosaccharides are the simplest form of a carbohydrate‚ disaccharides are made up of two monosaccharides and‚ polysaccharides are made up of three or more monosaccharides. Common foods we consume contain each of these classes of carbohydrates. Milk and fruit contain natural forms of simple sugars (monosaccharides)

different types of macromolecules. It is a reaction that leaves a macromolecule structure along the lines of developing its own specific function in a living organism. The 4 most common ones are carbohydrates which includes monosaccharides and polysaccharides‚ lipids‚ proteins and nucleic acids (Mack 2012). Scientists identify different types of macromolecules to achieve a better understanding on how they function in our bodies. This can be achieved by studying their chemical properties and structure
