Differentiation in plants refers to the processes by which distinct cell types arise from precursor cells and become different from each other. Plants have about a dozen basic cell types that are required for everyday functioning and survival. Additional cell types are required for sexual reproduction. While the basic diversity of plant cell types is low compared to animals, these cells are strikingly different. For example, some cells such as parenchyma cells retain the potential to respond to environmental and/or hormonal signals throughout their life and, under the right conditions, can be transformed into another cell type (transdifferentiation). Other cells such as the water-conducting vessel elements undergo cell death as part of their differentiation pathway and thus can never transdifferentiate to another cell type

How TF can Jason see if his flashlight isn't working?
Urea (CH4N2O), bi carbonate ion (HCO-3), creatinine, bilirubin are the ammonia containing products, are eliminated by kidneys through urine by a process of transamination.
Breakdown of amino acids results in formation of ammonium ions.
The elimination or excretion of urea is called ureotelism.
Answer:
Introduced to a new area, spreads rapidly, and displaces native species.
Explanation:
A species is invasive when they were not present in the area before, and once that they are there, they reproduce at a high peace. The fast reproduction rate, which leads to the spread of the species in the area, causes a disbalance in the ecosystem since it eats other species, which are native because they are from that area or other species' food. As a consequence, native species die or are reduced in number because the new species invaded their habitat.
An invasive species is not endemic because they are not native to that particular area. They are always external to this one.
