Taxonomy is the branch of Science, in which
we study the Classification of Organisms. On discovering an unknown organism,
begin classification by looking for anatomical features that appear to have the
same function as those found on other species.
In order to correctly classify an organism,
scientists use many modern tools.
1.Morphology describes the physical
characteristics of an organism. Typically, this is enough information to place
the organism within a domain and kingdom.
2.DNA and biochemical analysis allow
scientists to test less visible, but distinguishing, characteristics.
3.Comparing embryology allows scientists to
group organisms that share common fetal development.
<span>4.Evolutionary
phylogeny describes the evolutionary relationships between organisms.</span>These
relationships are deduced based on shared traits that may have been passed from
ancestor to new species. Traits
may include physical traits (ex. presence of jaws), or may be genetic traits
(shared genes).

Answer:
1. Cell
2. cell theory
3. Organismal theory
4. resolving power
Explanation:
The cell is the smallest known unit of all living organisms. They are called the building blocks of life. An organism can be unicellular (made up of one cell) or multi-cellular (made up of many cells).
2. Cell theory was formulated and developed by Schleiden, Schwann, and Virchow. They are considered as the basic principles of biology.
It states:
1. Living organisms are made up of cells.
2. Cells are the basic unit of life.
3. Cells are formed from pre-existing cells.
4. Energy flows inside the cell.
5. DNA is passed on from cell to cell.
6. All cells have the same basic chemical composition.
3. Organismal theory is the intended counter-argument of the cell theory. It was developed by Reichert, Strasberger, Sherrington, and Pavlov. It argues that the basic unit of life is the organism itself, suggesting that an organism came about from a cell that expanded.
4. Resolving power is the ability of an optical instrument like a microscope or a telescope to view objects that are close together as separate, abling the viewer to distinguish the two from each other.
