The Totonac people‚ who inhabit the Mazatlan Valley on the Gulf Coast of Mexico in the present-day state of Veracruz‚ were the first to cultivate vanilla. According to Totonac mythology‚ the tropical orchid was born when Princess Xanat‚ forbidden by her father from marrying a mortal‚ fled to the forest with her lover. The lovers were captured and beheaded. Where their blood touched the ground‚ the vine of the tropical orchid grew.[3] Drawing of Vanilla from the Florentine Codex (circa 1580)

(DF) is indigestible plant matter comprising of compounds such as cellulose‚ hemicellulose‚ lignin‚ pectin‚ β-glucans and gums. In the case of fruits and vegetables‚ cell walls and parenchymatous tissues are the dietary fiber supply. Dietary fibre is grouped into two major classes: polymers soluble in water (SDF)‚ such as pectin and gums‚ and those that are insoluble (IDF) – cellulose‚ hemicellulose and lignin. However‚ our primary concern is the SDF class‚ particularly

(Nelson and Cox 2005; Russell and others 2010). This experiment will investigate the effects of temperature on the enzyme kinetics – that is‚ the rate of an enzyme’s catalysis – of peroxidase isolated from turnip. Plant peroxidases are involved in lignin formation‚ which is part of the cell wall (Cosio and Dunand 1985). Turnip roots contain peroxidases which are enzymes that can be easily extracted‚ and because peroxidases can liberate oxygen from hydrogen peroxide‚ their activity can easily be measured

Coconut- Tree of Life The Coconut Tree (Cocos Nucifera L.) is called "The Tree of Life" because of the endless list of products and by-products derived from its various parts. Food‚ shelter‚ fuel - name it‚ the coconut has it. The coconut industry is considered a major dollar earner that provides livelihood to one-third of the country’s population. Coconut Meat From coco meat can be obtained coco flour‚ desiccated coconut‚ coconut milk‚ coconut chips‚ candies‚ bukayo or local sweetened shredded coconut

Tiffany Goh Biology SAC 3 “The Transport systems play an essential role in the survival of flowering plants and mammals” It is imperative that the organism’s cells have an ideal supply of the necessary materials to ensure its survival. At the same time‚ waste material must be removed to make room for the new material coming in and to avoid infection. Necessary substances and waste material merely move in and out of unicellular organisms by diffusion‚ osmosis or active transport due to direct
