Question

While exploring a local wooded area, you encounter what you believe to be a previously uncharacterized organism. Upon microscopic evaluation, you notice a single-celled organism about 1 micrometer, lacking a nucleus. What type of cell is this?a. nucelote b. prokaryote c. not enough information provided d. eukaryote

Answer 1

Answer:

B (prokaryote)

Explanation:

Life, in general, has been classified into three domains viz: Eukarya, Bacteria and Archaeae. The first (Eukarya) are organisms with a well defined membrane-bound compartment that houses their genetic material (DNA) called NUCLEUS. On the other hand, the other two domains are generally referred to as prokaryotic organisms because they lack this membrane-bound nucleus. Hence, their genetic material is found naked in a region of the cytoplasm called NUCLEOID.

Therefore, in this question, after microscopically observing and evaluating the uncharacterized organism, It showed that its cell lacked a nucleus. This immediately points out that the cell must be PROKARYOTIC CELL.
