1: plant growth and light color
a student wants to test how the color of light affects the growth of bean plants. she places one group under red light, another under blue light, and another under normal white light. all plants receive the same amount of water, soil, and temperature. she measures the height of the plants after two weeks.
some facts: the spectrum of light contains visible and non - visible light that is emitted from our solar system as radiation from our sun. light has different refractional indexes which cause them to bend and produce different colors. plants respond to light due to their chloroplast that houses an enzyme called chlorophyl (pigment/color). some accessory chlorophyl respond to various spectrums of light (carrots leafage is green and the carrot root is orange). this enzyme is activated by light and converts co2 and h2o to glucose (sugar) which allows the plant to grow.
12 label the parts of the graph based the testable question on the graph.

Explanation:

Step1: Identify Axes Purpose

The graph is for the experiment on light color and plant growth. The x - axis (horizontal) should represent the independent variable, which is the "Color of Light" (red, blue, white). The y - axis (vertical) represents the dependent variable, "Plant Growth" (measured as height). The title of the graph should be "The effect of color of light on plant growth" as it summarizes the experiment's question.

Step2: Match Labels to Graph Parts

• The top box (title area) should have "The effect of color of light on plant growth" as it's the overall topic of the graph.
• The x - axis label (horizontal axis) should be "Color of Light" since it's the independent variable manipulated in the experiment.
• The y - axis label (vertical axis) should be "Plant Growth" as it's the dependent variable being measured.

Answer:

• Title of the graph: The effect of color of light on plant growth
• X - axis label: Color of Light
• Y - axis label: Plant Growth
