Chapter 23, Problem 12WIO
Summary Introduction
To determine:
The other source that Jean Baptista Van Helmont failed to consider in his experiment about how plant acquire new mass as they grow when he added nothing but only water to plants.
Concept introduction:
Nutrient uptake is the process by which nutrients from external environment move into a plant. Plants obtain their nutrients from soil and air. Soil provides food, water, and nutrients to plants which are very essential for plant growth and development. Plants also obtain some essential nutrients from the atmosphere by the leaves.

In the early 1600s, Jean Baptista van Helmont investigated how plantsacquire new mass as they grow. He weighed a willow shoot andplanted it into soil that he had also weighed. After 5 years of addingnothing but water to the plant, he found that the soil had lost only alittle weight, while the plant had grown from 2 kg to about 76 kg. Hetherefore concluded, incorrectly, that water was the sole source of theadded plant material. What other source did he fail to consider in hisexperiment?
About 200 years ago, Jan Batista van Helmont wanted to know where growing plants get the materials necessary for increase in size. He planted a tree seedling weighing 2.2 kilograms (5 pounds) in a barrel filled with 90 kilograms (200 pounds) of soil and then watered the tree regularly. After 5 years, the tree had gained almost 75 kilograms (164 pounds), and the soils weight was unchanged. He incorrectly concluded that the tree had gained all of its additional weight by absorbing water. How did the tree really gain most of its weight?
Growers often wrap potted plants in plastic sleeves prior to shipping. If plants remain in these sleeves too long, their leaves curl and fall off. Imagine you are working at a garden center and have been asked to make a presentation to a local garden club.Question: Explain the processes that may cause the leaves to drop and fall.

- Jim hasn't been having success in growing strawberry plants for the past few years, so he got his soil checked for soil conditions. He received information that the soil was too acidic. He wanted to check if the acidity of the soll was the reason for the unsuccessful growth of strawberry plants. He added lime (adding lime neutralizes acidic soils) to half of his garden. He did not add any lime to the other half of the garden and planted strawberries in his garden. He found that he had juicy strawberry bunches on the side of the garden where lime was added. 1. What is the observation of this experiment? a) Jim does not know how to grow strawberries b) Strawberries do not grow on plants c) There is some problem with the soil d) Jim does not like strawberries 2. What is the control group in the experiment? a) Strawberries grown in the soil manipulated with lime b) Strawberries grown in the soil with no lime added c) Jim, who added lime to the soil d) Strawberries that were not growing in…arrow_forwardPaul Klein has a favorite plant which is Duranta repens.
