Hydroponic Vocab Review

In an experiment to compare the growth of plants in a hydroponic system, which of the following is considered qualitative data?

• The height of the plants measured in centimeters

• The number of leaves on each plant

• The color of the leaves

• The weight of the plants in grams

Given the following hypothesis:
"If seeds are exposed to more light, then they will germinate faster because light provides energy for growth."

Which of the following is the independent variable in this experiment?

• The amount of light the seeds receive
  

• The rate at which the seeds germinate
  

• The type of seeds used
  

• The temperature of the environment

Which of the following statements best describes what happens to the speed of the chemical reaction if an enzyme becomes denatured?

• The reaction speed increases significantly because the enzyme changes shape.

• The reaction speed remains the same, regardless of the enzyme's shape.
  

• The reaction speed decreases or stops because the enzyme's active site is altered.

• The reaction speed increases initially but then slows down as the enzyme returns to its normal shape.

Which of the following factors does NOT contribute to an enzyme denaturing?

• Extremely high temperatures

• Changes in pH levels

• Binding to the substrate

• Extremely low temperatures

In a hydroponics experiment, you want to test how different amounts of light affect the growth rate of lettuce plants. Which of the following is a properly written hypothesis using the "If, then, because" format that includes both the independent and dependent variables?

• If lettuce plants are grown with more light, then their leaves will turn greener because light affects chlorophyll production.

•  If lettuce plants receive more water, then they will grow faster because water is necessary for nutrient uptake.

• If lettuce plants are exposed to more light, then they will grow faster because light is essential for photosynthesis, which promotes growth.

• If lettuce plants are grown in different soil types, then they will grow better because soil quality affects nutrient availability.

In a hydroponics experiment, you are testing different growing mediums to see which one retains the most water for plant growth. Based on their properties, which of the following substances would have the greatest water retention?

• Rockwool

• Sand

• Perlite

• Gravel
