Because pioneer species are the first to return after a disturbance, they are the first stage of succession, and their presence increases the diversity in a region. They are usually a hardy plant, algae or moss that can withstand a hostile environment.
To determine whether a cell is a eukaryotic or
prokaryotic cell, one can observe certain features.
If the cell in the question possesses a well-defined
or definite nucleus and have membrane-bound
organelles such as mitochondria, chloroplasts,
Golgi apparatus, endoplasmic reticulum, the cell is
eukaryotic. If the cell has nucleoid or indefinite
nucleus and without membrane-bound cell
organelles, the cell is prokaryotic. If ribosomes in
a cell are the 80S (S=Svedberg units) type, the cell
is eukaryotic and if ribosomes are 70S type then it
is prokaryotic.
