Question 1
Which do you think is a more basic characteristic for classifying organisms?
(a) The place where they live.
(b) The kind of cells they are made of. Why?
The more basic characteristic for classifying organisms is the kind of cells they are made of because different organisms may share the same habitat but may have entirely different form and structure. So, the place where they live cannot be a basis of classification. Moreover, a particular dwelling place can be full of organisms of a wide variety.
