Chapter 37, Problem 14TYK

Using a technique called metagenomics, researchers found that

  1. a. all plant roots house endophytes.
  2. b. many plants exhibit some amount of heterotrophy when their roots take up and digest bacteria and yeasts.
  3. c. the “species” composition of bacterial communities vary the most between bacteria inside roots (endophytes) and soil bacteria in the rhizosphere.
  4. d. the composition of the soil (clayey or porous) does not affect the “species” composition of bacteria either inside or outside the rhizosphere.

Discuss the following prompt:     In this experiment, we are looking to see how much different types of soil will affect the time it takes for pinto Bean seedlings to germinate out of the ground. The scientific name of a pinto bean is Phaseolus vulgaris. Pinto beans are kind of beans people usually eating, and people commonly use pinto beans in many dishes, such as rice and pasta. Planting pinto beans need many necessary factors, however, I think the type of soil is the most important one to grow it faster. Pinto beans are kind of plants can grow in dark and dry area, so even in dark (less light), they can grow as well. The goal is to determine that soils have different characteristics that can help or hurt plant growth.       In order to discover the effects soils have on plant growth, three different soil samples will be used in a controlled study. The samples will vary in consistency, texture, color, location, moisture, and contact with human life to ensure that the samples are…
Imagine 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. Which graph or graphs would be most appropriate for portraying the results from your experiment? SELECT ALL THAT APPLY. Scatter plot Pie chart Bar graph Box plot Line graph
