Water Fern

Water fern

Water fern is a common name for several plants and may refer to:

Water

Water is an inorganic compound with the chemical formula H2O. It is a transparent, tasteless, odorless, and nearly colorless chemical substance. It is the main constituent of Earth's streams, lakes, and oceans. Water is also the fluid of all known living organisms, in which it acts as a solvent. Water, being a polar molecule, undergoes strong intermolecular hydrogen bonding which is a large contributor to its physical and chemical properties. It is vital for all known forms of life, despite not providing food energy or being an organic micronutrient. Due to its presence in all organisms, its chemical stability, its worldwide abundance, and its strong polarity relative to its small molecular size, water is often referred to as the "universal solvent".

Fern

Ferns are a group of vascular plants that reproduce via spores and have neither seeds nor flowers. They reproduce in two phases, a short-lived gametophyte that reproduces sexually to develop a spore-bearing leaf structure. Some ferns produce coiled fiddleheads, which expand into fronds.

Color of water

The color of water varies with the ambient conditions in which that water is present. While relatively small quantities of water appear to be colorless and transparent, pure water has a slight blue color that becomes deeper as the thickness of the observed sample increases. The hue of water is an intrinsic property and is caused by selective absorption and scattering of blue light. Dissolved elements or suspended impurities may give water a different color.
