A second smaller hole is also bored through each stopper through which is inserted short bent capillary tubing for passage of air. A healthy potted tomato or Vinca plant is selected and the pot is watered well before the experiment is started. N.B. After a few hours cross sections are made from different heights of the stem and observed under the microscope. The soil of the first pot should be saturated with water that of the second pot moderately watered (preferably a little above field capacity). Apr 8, 2017 - No matter from books and magazines television or the Internet, parents are bombarded with the message that science teaching for kids is very important. N.B. Half of the roots of another lot of four seedlings is removed and put in the second flask. Maximum water content is obtained in the seedlings growing in loamy soil and minimum in sandy soil. This soil possesses its good porous nature due to presence of sand while clay and silt increase its Water-holding capacity. The water travels up the stem of the plant into the leaves and flowers where it makes food and helps keep the plant rigid. (2012, August 1). Find out how fresh and salt water mix together in this water cycle worksheet. From this data the amount of water absorbed per gm of seedling per hour is calculated. You’ve just watered a thirsty plant, and its roots are starting to absorb the water from the soil. Some of the factors are: 1. - Learning how plants absorb water! In highly transpiring plants, a negative root pressure develops. Quick water science experiments are perfect anytime! The influence of different plant parts and other factors on the rate of absorption of water may be studied as follows: (b) Effect of dry and humid atmosphere by keeping the plant in dry or humid condition. ...
