2024 REDO Part 1 Pre-lab/ P and CR Algae beads Lab CFU

Front

What is the main question being tested in the algae bead experiment?

Back

The main question is: How does Algae exposure to light impact the pH of the CO2 indicator solution?

Front

What is an experimental group in an experiment?

Back

An experimental group is a set of subjects that are exposed to the variable being tested, in this case, algae in the indicator solution placed in the light.

Front

What is the control group in the algae bead experiment?

Back

The control group would be algae in the indicator solution placed in the dark, as it does not receive the experimental treatment of light.

Front

Define pH in the context of the CO2 indicator solution.

Back

pH is a measure of how acidic or basic a solution is, which can change based on the presence of CO2 and the activity of algae.

Front

What role does light play in the algae bead experiment?

Back

Light is a crucial factor as it influences the photosynthesis process in algae, which can affect the pH of the solution.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

How does increased CO2 affect pH levels in a solution?

Back

Increased CO2 levels typically lower the pH, making the solution more acidic.

Front

What is the purpose of using an indicator solution in this experiment?

Back

The indicator solution is used to visually show changes in pH, indicating the effects of algae activity.

Front

What is the significance of using algae beads in the experiment?

Back

Algae beads provide a controlled way to study the effects of light on algae without the complications of free-floating algae.

Front

What is the expected outcome of exposing algae to light in this experiment?

Back

The expected outcome is that the pH of the CO2 indicator solution will increase due to the photosynthesis process, which consumes CO2.
