Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following is true about prokaryotic and eukaryotic organisms?
A
Prokaryotic organisms can be unicellular or multicellular.
B
All unicellular organisms are eukaryotic
C
Eukaryotic organisms can be unicellular or multicellular.
D
All multicellular organisms are prokaryotic
Explanation: 

Detailed explanation-1: -While prokaryotes are always unicellular organisms, eukaryotes can be either unicellular or multicellular. For example, most protists are single-celled eukaryotes!

Detailed explanation-2: -Prokaryotes are always unicellular, while eukaryotes are often multi-celled organisms. Additionally, eukaryotic cells are more than 100 to 10, 000 times larger than prokaryotic cells and are much more complex. The DNA in eukaryotes is stored within the nucleus, while DNA is stored in the cytoplasm of prokaryotes.

Detailed explanation-3: -Eukaryotes may be either single-celled or multicellular. Eukaryotes are differentiated from another class of organisms called prokaryotes by way of the presence of internal membranes that separate parts of the eukaryotic cell from the rest of the cytoplasm. These membrane-bound structures are called organelles.

Detailed explanation-4: -Ribosomes are found in both prokaryotic and eukaryotic cells.

Detailed explanation-5: -These organisms carry out all functions required for their maintenance and survival using one cell. Therefore, prokaryotes are unicellular and not multicellular.
