Carnivorous Plants In a world where plants are at the bottom of the food-chain‚ some individual plant species have evolved ways to reverse the order we expect to find in nature. These insectivorous plants‚ as they are sometimes called‚ are the predators ‚ rather than the passive prey. Adaptations such as odiferous lures and trapping mechanisms have made it possible for these photosynthesizers to capture‚ chemically break-down and digest insect prey (and in some cases even small animals.) There

Biology Revision Notes Biochemical Tests: Proteins - add biurettes reagent to the sample. If protein is present‚ clear colour change from blue to purple. Reducing Sugars – add Benedict’s reagent to the sample. Heat in Bunsen or water bath. If reducing sugars are present‚ clear colour changes from blue -> orange red precipitate. Lipids – dissolve sample in ethanol. Slowly pour the solution into the water slowly. If lipids are present a white emulation forms on the surface. Starch – add iodine
