Chapter 22, Problem 3WIO
Summary Introduction
To determine:
The cause for the stoppage of growth of one out of the two plants grown on identical soil and providing them water for the same amount at the same time interval.
Concept introduction:
Growth is a process in which an organism increases in shape, size and in overall body structure and function and length. Growth in plants is a feature that continues for a very long time. It occurs at a very rapid rate and that is the reason for most of the plants being tall. The growth of a plant depends on many factors like the sunlight, nutrients, genetic factors, physiological conditions like temperature of the surrounding,

A scientist is studying the effect a new fertilizer has on root growth on bean seedlings.
Three groups of plants are grown in the same location in a greenhouse, each receiving the
same amount of sunlight and water every day. The scientist measures the length of the
roots for each plant every day. The scientist then calculates the mean for each group for
five days. The results are shown in the following table.

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.
Imagine an experiment where I am testing the effects of salt on the growth of corn plants. I set up several treatments where some plants get no salt, some are watered with a 0.05% salt solution, and some are watered with a 0.1% salt solution. I use the same species of plants, the same soil, and the same total amounts of water in my experiment. Every other day I record the height of the plants in cm.
What is the independent variable in my experiment?
What is the dependent variable in my experiment?

A small dose of fertilizer can enhance plant growth, but overfertilization can kill the plant. Why might overfertilization have this effect?arrow_forwardImagine you were testing how the presence/absence of soil bacteria affected plant growth. In this experiment you had two treatments - one with soil bacteria present, the other with soil bacteria absent. To determine how soil bacteria affected plant growth, you then measured plant height after 1 month. You find that plants grow taller in the treatment with soil bacteria compared to the treatment with no soil bacteria.

- Select the statement equivalent to:If you water the seeds, then they will sprout. If you do not water the seeds, then they will not sprout. You water the seeds or they do not sprout. You do not water the seeds or they will sprout. You water the seeds and they do not sprout.arrow_forwardUrkle decided he wanted to test the effects of watering his plants with cold coffee. For a week he watered one group of plants cold coffee. He ignored the other group of plants. Urkle has no idea what might happen to plants that receive coffee. What is wrong with Urkle's experimental design? If Urkle wants to test the effects of cold coffee on plant growth, he should water his control group with cold water. If Urkle wants to test the effects of cold coffee on plant growth, he should water the plants in the other group with Dr. Pepper. If Urkle wants to test to test the effects of cold coffee on plant growth, he should water the plants in the other group with hot coffee. If Urkle wants to test the effects of cold coffee on plant growth, he can ignore the control group as long as he makes sure both groups get the same amount of sun.arrow_forwardGrowers often wrap potted plants in plastic sleeves prior to shipping.

- You are an amateur gardener and are reading an article that explains that plants need only five basic factors for growth: sunlight, water, air, nutrients, and a substrate on which to grow (soil). You want to investigate the role that these variables play in plant growth. You decide to test the substrate and see if changing substrate mixes will affect plant growth. Match the following experimental components with their descriptions. Experimental Components: ( Experimental Variable, Dependent Variable, Control Condition, Independent Variabe, A Confounding Variable That Must Be Held Constant) 1. type of substrate used: 2. growth resulting from substrate type 3. amount of water needed in all plants 4. substrate that is changed during the experiment 5. substrate that is not changed during the experimentarrow_forwardThey started to read books, surf the internet and study researches on the effect of music to plant growth, Members from the group continued to formulate their respective hypotheses. They went on performing a simple experiment. The group selected two San Francisco plants of similar size planted on the sanme type of soil and kind of pots. Both plants were healthy. Each plant were placed in separate rooms with a window exposed to full sunlight and were watered with equal amounts every day. They measured the height of the plants. Once a day, they played classical music on room 1 for about one hour while leaving room 2 with no music played. Over a period of two weeks, they noted significant differences in each plant's growth. Multiple Choice: Write the letter of your answer before the number. What was the problem in the Grade 7-Rizal's experiment? Which San Francisco plant is taller? What kind of music should be given to plants? 1. a. How long can plants grow? d. Does music make a plant…arrow_forwardErin hypothesizes that a certain fertilizer will cause her sunflowers to grow better. She plants 12 plants chooses the first 6 that sprout to treat with the fertilizer. She measures all the plants daily, and notices that the treated plants were an average of 2 cm taller at 6 weeks. She concludes that the fertilizer causes the plants to grow faster. Which fact would lead you to question Erin’s conclusion? The first plant to sprout was treated with the fertilizer. Erin treated the first 6 plants that sprouted. The treated plants were an average of 2 cm taller at 6 weeks. Erin’s friends also conducted the same experiment.arrow_forward
