A translocation in which part of one chromosome is exchanged with a part of a separate non-homologous chromosome. ~ s are the result of moving a section of the genetic material (chromosome) of the cell and attaching it to another chromosome.
Plants actually create these compounds to ensure a healthy, diverse population of bacteria lives near their roots to protect the plants. Decomposers are especially important in retaining nutrients in their cells thus preventing loss of those nutrients from the root zone. This is very important in the nitrogen cycle.
This seasonal event is not really algae; rather, it is photosynthetic bacteria called cyanobacteria that rely on sunlight for energy. As they store energy, they create a tiny cavity of air that allows them to move up and down in the water to areas with more nutrients.
