Question

A new species of single cellular organism has been found in a sample of deep ocean water. Which of the following descriptions would be consistent with classifying the object as prokaryotic? (Mark all that apply)

A. Presence of mitochondria
B. Presence of ribosomes
C. Presence of peptidoglycans in the cell wall
D. Presence of DNA in the cytoplasm
E. Presence of cilia

Answer 1

To classify the new species as prokaryotic, we need to look for specific characteristics. Prokaryotic cells do have ribosomes and peptidoglycans in their cell walls, and their DNA is found in the cytoplasm. They do not have mitochondria or cilia.

Step-by-step explanation:

In order to classify the new species of single cellular organism as prokaryotic, we need to look for specific characteristics. Mark all the descriptions that apply:

1. Presence of mitochondria: Prokaryotic cells do not have mitochondria. Mitochondria are membrane-bound organelles found in eukaryotic cells.
2. Presence of ribosomes: Prokaryotic cells do have ribosomes. Ribosomes are found in all types of cells, including prokaryotes and eukaryotes.
3. Presence of peptidoglycans in the cell wall: Prokaryotic cells do have peptidoglycans in their cell walls. Peptidoglycans are a characteristic feature of bacteria, which are prokaryotic organisms.
4. Presence of DNA in the cytoplasm: Prokaryotic cells do have DNA in their cytoplasm. Unlike eukaryotic cells, prokaryotic cells do not have a nucleus.
5. Presence of cilia: Prokaryotic cells do not have cilia. Cilia are found in some eukaryotic cells, such as animal cells.
