cohesion-tension theory. The molecules of water are attracted to the walls of the xylem (adhesion) due to its polar structure‚ and to each other (cohesion) so it moves up the stream because the walls of the lignified xylem can take the pressure. In transpiration water evaporates from the surface of the leaf‚ and therefore the substances from the soil are drawn up. The sugars produced by photosynthesis are also dissolved in water and carried to respiring cells. Water is an essential ingredient in photosynthesis

Chapter I Introduction Background Aloe barbadensis is usually cultivated in warm climates. It has over 250 species and only 5-6 kinds are used for medicinal practices. It is one of the most frequently used aloe plant. According to the National Center for Complementary and Alternative Medicine‚ aloe vera was used only to heal wounds and for various skin conditions. But nowadays‚ it is used in different ways‚ like for traditional remedy for a variety of conditions‚ including diabetes‚ asthma

Managing the Root Zone in Soilless Culture Author: Eyal Ronen Haifa Chemicals Chief Agronomist In solid growing media‚ there are five important parameters that should be monitored around the root zone to optimize plant growth and yields. EYAL RONEN offers some guidelines on how to manage these parameters to prevent major crop problems‚ and explains the importance of measuring fertiliser solution at both the dripper and drainage points. General terminology Soilless culture‚ commonly referred to as

Abstract Stomata is important to plants because of their role in gas exchange and photosynthesis. Clear nail polish and clear plastic tape were used to make leaf impressions of A. floridanum. Once impressions were completed‚ compound microscopes were used to count the total number of stomata per slide. The counts of stomata were used to find stomatal densities‚ along with the open/closed ratios of stomata. Stomatal density and open/close ratio of stomata did not differ between the two locations

Water is an odorless‚ colorless‚ tasteless chemical compound that makes up well more than half of the human body. In addition to being prominent in the make-up of the human body‚ it also covers all but approximately 30% of the Earth’s surface‚ and can be found naturally in all three states of matter: liquid‚ solid and gas. Water is a covalent bond known most commonly by its empirical form; H2O. It can also be identified by the Lewis Dot Structural form shown in the figure in the upper right corner

Just as humans have essential needs for survival‚ all plants require several basic elements to grow and thrive‚ including… Soil minerals (the more nutrient-rich the soil‚ the better the plant will grow) Water Air (carbon dioxide‚ hydrogen and oxygen) Sunlight Proper soil temperature Proper air temperature How much a plant needs of each element initially depends on the plant’s original habitat.
