Nutrient and Water Delivery


A vital part to having a plant is making sure it is supplied with food and water. In order for the plant to be emergy filled, it needs to have mass flow from roots to shoots and the only way it can do that is if the plan is clear and cool. Plants need to go through transpiration which is almost like a plants form of sweating. This happens in the plants pours, or stoma. It needs to go through this process to make sure the osmotic flow is good. This is also caused my turgor pressure which is the pressure that there is in the plant to sustain its shape and effectiveness. All this water pressure is in the vascular tissue. Vascular tissue is the tissue in the plant that is responsible for carrying all the liquids and food throughout the cell. The components of vascular tissue are xylem and phloem. Xylem is the transport tissue that delivers all the nutrients to the plant. As the cooling system and to allow evaporation to happen, the stoma is the little pours on the leaves. But these pours on the leaves need to be regulated so they don’t open too wide or are too narrow so there are guard cells that surround the stoma. However a good nutrient delivery system isn’t worth anything if there are no nutrients. The soil that the plant is in has to do with its growth because each different plant will need different chemicals to keep it thriving. So the soil needs to be replenished with nutrients and the soil must be able to hold water for the roots to pick up. To keep everything together, right inside the cell wall, there is a casparain strip which is responsible for keeping passing flow of materials.
