Question 1

True or false: Sphagnum moss is a type of algae that grows primarily in saltwater marshes.

Accepted Answer

False. Sphagnum is a moss (bryophyte), not algae, and it thrives in acidic freshwater bogs and wetlands, not saltwater.

Question 2

True or false: Sphagnum moss is the primary ingredient in most commercial peat moss sold for gardening.

Accepted Answer

True. Peat moss is largely composed of decomposed Sphagnum, harvested from bogs and used to improve soil aeration and acidity.

Question 3

True or false: Sphagnum moss is a flowering plant that produces seeds for reproduction.

Accepted Answer

False. Sphagnum is a non-flowering bryophyte; it reproduces via spores, not seeds, and lacks true roots or flowers.

Question 4

True or false: Sphagnum moss can hold up to 20 times its dry weight in water, making it a natural sponge.

Accepted Answer

True. Sphagnum’s hollow cells act like sponges, absorbing 16–20 times their dry weight, which helps create waterlogged bogs.

Question 5

True or false: Sphagnum moss was historically used as wound dressing because it has mild antiseptic properties.

Accepted Answer

True. Its acidic nature and ability to absorb liquids made it a popular wound dressing in World War I, reducing infection risk.

Question 6

True or false: Sphagnum moss can actually raise the pH of acidic soil, making it suitable for alkaline-loving plants.

Accepted Answer

False. Sphagnum moss is acidic (pH 3–4) and lowers soil pH, making it ideal for acid-loving plants like blueberries, not alkaline.

Question 7

True or false: Sphagnum moss contributes to climate change by releasing large amounts of methane gas.

Accepted Answer

False. Sphagnum bogs actually store vast amounts of carbon; while some methane is produced, they are net carbon sinks.

Question 8

True or false: Sphagnum moss can be used to filter heavy metals from water due to its ion-exchange capacity.

Accepted Answer

True. Sphagnum’s cell walls exchange hydrogen ions for heavy metals like lead and copper, acting as a natural water filter.
