Let's eliminate this one by one.
Animal cell does not have walls. So we can eliminate The third option.
Plant cells does have walls, but they also have well-defined nucleus. So we can eliminate the second option
The leave : A. Prokaryotic as the answer
hope this helps
they have specialised cells ?
Answer:
All viruses are obligate parasites; that is, they lack metabolic machinery of their own to generate energy or to synthesize proteins, so they depend on host cells to carry out these vital functions.
<span>2. Different kinds of eukaryotes have different numbers of chromosomes.</span>
There are differences between Eukaryotic and Prokaryotic cells. This difference is considered to be the most important distinction between groups of organisms. A Prokaryotic cell does not contain a nucleus. It only contains one chromosome and is a single-celled organism. It was the only form of life on earth for millions of years. Examples of a Prokaryotic cell are the different types of bacteria present today.
A Eukaryotic cell contains a nucleus; more than one chromosome and is typically a multi-celled organism. Both plant and animal cells are eukaryotic cells.
I think the answer is D. ( or supported by observations ). Because theories change over time, they both NEED to be proven, they do NOT go off of consensus, but they do NEED to be supported by observations.
