Fibroblasts secrete fibrous proteins and ground substance, which together form the extracellular matrix that is the basis of connective tissue. fibroblast is a cell that manufactures and maintains connective tissue, the structural framework that supports the organs of all animals.
Therefore, there is very little chlorophyll in these tropical waters, keeping them clear. (As an aside, corals are symbioses where phytoplankton have evolved to survive in nutrient-poor tropical waters by living inside the bodies of the corals and obtaining nutrients directly from the waste products of the corals.
Muddy, cloudy water is not only unattractive, but can be harmful to aquatic life. Although high sediment loads in ponds seldom kill sport fish directly, muddy waters can seriously reduce fish production.High suspended sediment loads in ponds can result in the following problems:ll other things being equal, clear water ponds can produce many more fish than muddy ponds. Muddy water reduces fish food availability, and interferes with the ability of fish to see and catch prey. Muddy waters favor blue-green algae and bacterial growth, which can impart a bad flavor to drinking water and food fish.
