All the seaweed they reproduce by the presence of spores that are generated at different levels in the evolution of the colony. In some cases these levels of evolution are appreciable since the different generations of algae often present totally different appearances.
They are the only organ that acts as a stem and leaves. The root system present in algae plants is reduced solely to the objective of fix the organism to the substrate or rock.
Their presence is part of the biodiversity of the aquarium. To a greater or lesser extent, they are always present in different forms depending on the elements present or absent that affect them. allow to develop.
They are the most primitive elements of the plant kingdom, they do not have a vascular system. The anchoring system to the substrate used is called rhizoid and does not serve for the assimilation of nutrients. The absorption of nutrients is assimilated by algae across the surface of your body. Some species have a creeping grip axis called a rhizome or stolon.
What causes them
The type of light and its photoperiod, nitrogenous compounds, wastes and trace elements or traces, will cause the algae present in our aquarium as well as its type. If the conditions are really optimal for its development, the present type will reach the level of plague and will begin to harm other organisms such as sponges or corals that have no defense against an invasion of ground cover algae.
In an aquarium with new water in the presence of light with the appropriate amount of nitrate and phosphate the green filamentous algae will find your ideal environment to develop. When the traces necessary for the growth of green algae are consumed, you are dying giving way to other types of algae capable of growing with this chemical element consumed.
