Xylem

Do you like water? Yes? Then you must like 75% of me ;) and if you don’t like water then well, pray that you don’t die because all life is dependent upon water. H2O is the water molecule and is joined by covalent bonds. It is dipolar due to the bonding because the oxygen atom is slightly negatively charged while the hydrogen atoms are slightly positively charged. This polarity of water allows it to bond with other water molecules through hydrogen bonds. These hydrogen bonds are weak but in…

of the extra surface area that the root hairs provide (Gillaspy, 2008). Once water and minerals have diffused into the roots and root hairs, there are two types of tissue that helps transport the minerals and water through the stem to the leaves; xylem and…

incidentally as egg masses in elaborate or farming plant foliage (http://ipm.ucanr.edu/EXOTIC/index.html). Glassy-winged sharpshooter sustains on plants through straw-like mouthparts embedded into the xylem tissue which conducts water all through the plant. Since supplements are weakened in xylem liquid, Glassy-winged sharpshooter must process huge volumes to address dietary issues. Therefore, these bugs produce extensive measures of watery excreta and are a social annoyance as the fluid…

Title: Importance of photosynthesis in agriculture. Introduction: photosynthesis is the process by which plants and some bacteria convert energy from the sun into food or chemical energy, This is how plants survive. This is the chemical reaction that takes place inside the leaf of a plant. This is what makes plants green and healthy.Photosynthesis has a vital role in agriculture. It allows crops to turn energy from the sun into a food source it helps the growth of the crop. It provides…

Overall, these properties allow it to: provide habitats for animals; transport substances around organisms; regulate and participate in cell reactions and help animals maintain a constant blood temperature. Water’s small size is important for plants as it is able to diffuse by osmosis into plant cells which creates turgor as the vacuole swells pressing against the cell wall. This pressure helps plants stand up straight and not wilt causing death As water is lost by transpiration from the…

ultimately affect the amount of carbon dioxide that is consumed and produced. To start the light dependent stage of photosynthesis, sunlight is needed for the initial energy in which the chlorophyll in the chloroplast harnesses. Water is taken in by the xylem tissues in the roots. The water molecules are split and oxygen is released into the air. The same oxygen we are using to breathe currently. The other product of the water splitting is the hydrogen ions. The light is there to power the…

a) Why do you think is it important to put the bundles of asparagus in water? /1 It is important to put the bundles of asparagus in water. This is because the asparagus will wilt with its water source (the roots) removed. By putting the asparagus’ cut bottoms into water, water will be transported through its vascular tissue systems to the stems and leaves. Then, the asparagus will be able to photosynthesize with the water supply, sunlight, and carbon dioxide, and make food to function. Then,…

Oaks trees (Quercus species) have adaptations to withstand drought but the trade off of those adaptations is multiple long-term negative effects on photosynthesis. These adaptations help to tolerate harsh conditions, specifically in drought. In situations of long periods of drought it has been researched that oak trees lose their ability to effectively perform photosynthesis. Photosynthesis is the process in which sunlight is converted in to chemical energy. Plants make their own food by using…

Cressa cretica L. (Convolvulaceae) is mentioned as an ayurvedic drug, known in India as Rudanti. It is reported to be antibilious, antitubercular, and an expectorant. It is a remarkable salt-tolerant plant, common in coastal areas. The main of this work to analysed the morpho-anatomy of the leaf and stem, in order to supply knowledge to the medicinal plant identification. The morpho-anatomical studies reveals that leaves numerous, isobilateral, subsessile, acute, densely silky hairy,…
