The most abundant compound that can be found in the sea apart from water is the sodium chloride (NaCl). This is why we are able to retrieve table salt, which also comes in the same formula, from the sea. When sodium chloride dissociates into its ions, the two ions would be Na+ and Cl- which are called sodium ion and chloride.

Explanation:
Phototropism is the growth of organism characterize by their response to light stimulus. It occurs mainly in plant and some Algae.
The response of plant to light enable them use energy from light needed for photosynthesis.
Plant Phototropism characterise some plant growth and development such as flowering,fruiting and seedling formation.
Inability of plant to respond to light reduces it ability to photosynthesize and make sugar needed for their activities ,flower and fruits. It reduces it growth and development.
We have positive and negative response. Positive response is the response of plant towards the direction of light while negative response is the response of plant away from light.
