tape. POSSIBLE HYPOTHESIS: The water will travel from the glass to the flower making it change color. OR The water will not travel up the flower and nothing will change. POSSIBLE CONCLUSION: The water traveled up the xylem tubes to the flower petals. The color moves through the xylem allowing the color to be distributed throughout the cells of the petals causing their color to change. B.) --Putting Toothpaste To The Test PURPOSE: To find out if different brands of toothpaste remove different liquids

cells that having many intercellular spaces to allow the passage of gases‚ such as the intake of carbon dioxide for photosynthesis to take place. The stomata is the way in which these gases are exchanged‚ as well as the transpiration of water from the xylem‚ either by the apoplast or symplast pathway. Palisade cells are positioned towards the upper surface of the leaf and contain the largest number of chloroplasts per cell in plants. This makes them the primary site of photosynthesis in a plant’s leaves

Adenosine Triphosphate Adenosine triphosphate (ATP) is considered by biologists to be the energy currency of life. It is the high-energy molecule that stores the energy we need to do just about everything we do. It is present in the cytoplasm and nucleoplasm of every cell‚ and essentially all the physiological mechanisms that require energy for operation obtain it directly from the stored ATP. (Guyton) As food in the cells is gradually oxidized‚ the released energy is used to re-form the ATP so

Biology- Maintaining a Balance Summary 1. Most organisms are active in a limited temperature range 1. identify the role of enzymes in metabolism‚ describe their chemical composition and use a simple model to describe their specificity on substrates Enzymes are proteins which act as catalysts in living things (they lower the amount of energy needed for a reaction‚ therefore increasing rate of reaction). Enzymes speed up reactions but are not used up by them. Enzymes catalyze only one
