Sugar water versus salt water: What effect did they have on seed germination?
Purpose
The purpose of this experiment was to figure out what types of water would have an effect and what that effect would be on seed germination.
Background information
Plants need nutrients to survive. These nutrients can include nitrogen, calcium, phosphorus, magnesium, sulphur and iron. The plant absorbs these nutrients through the roots from the soil. These thing aren’t the only things plants need to survive though, they need things like water, sugar, and salt. The roots can allow many different things to pass into the plant. It selects many things such as nitrogen, water, and calcium. There are many ways that the plant can get its sugar. Photosynthesis within the leaves and the roots. The roots cannot make the sugar, however, they can let natural sugars from the soil/water into the plant. “Plants grown with a small amount of sugar added to its water generally appeared healthier“ (How Does Sugar Water Affect the Plant’s Growth?). This states that the plant can actually get sugar from its roots rather than photosynthesis. Most plants need sugar to develop, so the plant will happily take in the extra supply. Not only do the plants need all these nutrients and energy, but they can also take in salt. As Salinity Management.org said, “Salt exists in water as ions. Up to a certain amount of these ions can be beneficial to a plant.” (Learn About the Effects of Salt on Plants). This
