Water transport in plants Lesson objectives:1) Be able to describe how water moves through a plant 2) Be able to name some structures relating to water movement Okay to start off with lets recap. What is the word equation for photosynthesis? light energy carbon dioxide water glucose oxygen chlorophyll Where about in the plants environment do they collect the water from? From the soil So how does the water get from the soil into the root? The root hair is in fact not a hair like on your head, but it is an extension of the root cell. The root hair increases the surface area of the cell, this means that more water can be absorbed by the plant. From the root the water passes into special transport vessels called the xylem Xylem Vessels The xylem vessels are found from the tip of the root all the way up the stem to the leaves of any plant. They are quite large and carry nothing but water around the plant. They are also responsible for helping to keep plants nice and upright, instead of being wilted. The importance of water + H 2O Okay but how does the water get up to the leaves? Water is lost at the top of the plant through the stomata This water loss sucks up water from lower down in the plant This then pulls water from the soil into the roots The water loss from the stomata is why rainforests are so humid.
