Humans are a large contributor to water pollution. Toxic substances‚ algal bloom‚ and sedimentation are all results of human activities. If man does not become aware of their negligence and carelessness towards the environment‚ rivers‚ lakes‚ and other water supply systems will be depleted. The Clean Water Act in 1972 and the

Introduction Mangrove swamps are a type of coastal wetland found on five out of seven continents between the latitudes 30ºN and 30ºS. Mangrove swamps are rich communities of both vegetative and animal species. The swamps are unique in the fact that they are a highly vegetated area found on the edge of marine coasts. The major vegetation in this area has adapted to absorb its water from the sea‚ and its oxygen from the air as opposed to the soil. This environment serves as home to many animal species

concentrations that result in a loss of nutrient uptake in aquatic vegetation. Over time‚ heavy metals saturate wetlands and are consumed by wildlife‚ causing deformities‚ cancers‚ and even death in both aquatic and terrestrial animals. Stormwater leads to algal blooms‚ which deplete oxygen levels in the water. Some of the algae produced is toxic to aquatic organisms. An abundance of algae can shelter other aquatic plants‚ preventing them from proper sunlight and limiting photosynthetic capabilities. Osmond‚

Introduction Submerged aquatic vegetation (SAV) are plants that have adapted to live within aquatic environments (DNR 2011). SAV are able to float in the water and move with the currents because they contain specialized cells called aerenchyma that provide buoyancy and they lack the more rigid structures of most terrestrial plants (DNR 2011). Many different species of SAV are found throughout estuarine waters worldwide and there are seventeen species of SAV that are commonly found throughout

The Growth of Bacteria Influenced by Different Antibiotics Introduction: Plants are made up of three basic kinds of tissue that help it carry out basic functions that are necessary to maintain life and proper photosynthesis. The first and outermost layer of tissue is called the dermal layer. This is the plant’s ‘skin’ and serves the plant mainly as a source of protection. Also present in the dermal layer of the leaves are stomata‚ which are tiny openings that allow carbon dioxide to enter

physically or genetically. For instance‚ the plant-like protists aren’t enough like plants to be one. The characteristic that makes algal protists (algae) plant like is the ability to do photosynthesis. Similar to plants‚ plant-like protists have __chloroplasts__ that contain the pigment chlorophyll‚ which collects and converts light into energy. In addition to green‚ algal protists may be red‚ brown‚ or gold; their colors come from the presence pigments that mask the green of chlorophyll found in chloroplasts
