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,

Identify each activity as an observation, a hypothesis, an experiment, or a conclusion.
(a)The leaves of the pea plants that received too much water turned yellow.Observation
(b) Jill decided that 5 hours of indirect sunlight gave optimum growth
.
(c) Jack gave the pea plants a controlled amount of water each day.
(d) Jill thinks that too little sunlight will affect plant growth.
Scenario:
I planted a monggo seed and put red cellophane over one, and blue cellophane on the other in order to observe the plant growth.
Question:
a. How does the red color affect the seedlings of plants in terms of growth?
b. How does the blue color affects the seedlings of plant in terms of growth?
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?
What is the control treatment in my experiment?
What are three controlled variables in my experiment?

- Erin 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_forwardTHree factors that affect plant growth are soil health, nitrogen fixation, and sunlight.

- what do you think would happen to the roots of a plant if you turned the plant upside down for two weeks? explain your answerarrow_forwardExperiments usually have several controlled variables. These are variables that must be kept constant in all parts of an experiment. For example, if an experiment is testing the effect of sunlight on the growth rate of 5 seeds, the only variable that should change should be the amount of sunlight. All other variables should remain the same to ensure that sunlight is the only aspect affecting the results. The other variables, such as soil type, amount of water, type/amount of fertilizer, are the controlled variables. Looking back at the simulation experiment on the meteorite, describe two variables that should have been controlled.arrow_forwardIf a plant can improve its ability to obtain water by growing more roots, why shouldn’t the plant always grow more roots?arrow_forward
