Because DNA tells us how organisms are classified

Because similarities in DNA between two organisms may indicate a relationship

Because visible differences or similarities alone between two organisms might be misleading

Because DNA is inherited as it is passed down from related organisms and related organisms will thus share similar DNA

Classification can be made through observing shape and color alone.

Genetic studies are very powerful tools that can help classify organisms.

The number of domains and kingdoms is absolutely true and cannot be changed.

It is easy to classify organisms because they are all so obviously different.

Identifying cell wall composition is very useful for classification.

Animal cell walls contain collagen.

Protista is known for organisms that are easy to classify.
