These cells have DNA in a region called the nucleoid
|
|
|
Some of these cells have structures like flagella and microvilla
|
|
|
These cells have cell walls made of polypeptides and polysaccharides
|
|
|
These cells have cell walls made of cellulose
|
|
|
These cells have DNA contained in a nucleus
|
Detailed explanation-1: -The characteristics that apply only to prokaryotes from the list given above would be as follows:-These cells have DNA in a region called the nucleoid.-Some of these cells have structures like flagella and microvilli.-These cells have cell walls made of polypeptides and polysaccharides.
Detailed explanation-2: -select the characteristics that only apply to prokaryotes. these cells contain membrane bound organelles. these cells have DNA contained in nucleus. these cells have DNA in a region called the nucleoid.
Detailed explanation-3: -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-4: -The cells of all prokaryotes and eukaryotes possess two basic features: a plasma membrane, also called a cell membrane, and cytoplasm. However, the cells of prokaryotes are simpler than those of eukaryotes. For example, prokaryotic cells lack a nucleus, while eukaryotic cells have a nucleus.
Detailed explanation-5: -All cells have a plasma membrane, ribosomes, cytoplasm, and DNA. Prokaryotic cells lack a nucleus and membrane-bound structures. Eukaryotic cells have a nucleus and membrane-bound structures called organelles. 24-May-2021
