Tubes for Transporting Food-carrying tubes Phloem Water-carrying tubes Xylem Sugar is produced In the leaves. The food-carrying tubes transport this sugar from the leaves to the other parts of the plant. The root hairs found on the roots Take in water and mineral salts from the soil.
The theory of common descent states that all living organisms are descendants of a single ancestor. Phylogenetic trees and cladograms are often used to hypothesize the evolution of various organisms and shared common descent.

Answer:
The researchers were unable to grow the microbe in the laboratory BECAUSE THE PREVAILING ROOM TEMPERATURE IN THE LABORATORY IS UNSUITABLE FOR THE GROWTH OF THE MICROBE.
Explanation:
Microbes that grow near deep sea thermal vent usually have the ability to exist in environment that have abnormally high temperatures. In order for a researcher to grow such microbes in the laboratory, he must be able to reproduce the high temperature that is found in the natural habitat of the micro organisms. Growing the microbes in the laboratory at room temperature will be unsuccessful because the microbes can not survive at that temperature.
Measuring photosynthesis via the production of oxygen. Oxygen can be measured by counting bubbles evolved from pondweed, or by using the Audus apparatus to measure the amount of gas evolved over a period of time.The emerging bubbles are either simply counted or they are recorded using light barriers, which is very difficult because of their small size and often varying ascent rate. The gas bubbles generated during photosynthesis by aquatic plants produce distinctive sound pulses when leaving the plants.
