Question

name
comparing prokaryotes and eukaryotes
prokaryotes = bacteria
pro = no nucleus
pill
dna
cell membrane (plasma membrane)
cell wall
ribosome
flagellum
prokaryotes, which include bacteria, are the simplest of all the cells. all prokaryotes have dna. they also have ribosomes to make proteins. they do not have a nucleus or \membraned\ organelles. they are surrounded by a cell membrane and an outer cell wall. all bacteria are prokaryotes, and all prokaryotes are bacteria. they are found everywhere. they are thought to be some of the oldest life forms on earth. they are all unicellular.

1. what four characteristics do all prokaryotes have in common?
2. what living organisms are prokaryotes?
3. what main structure is not in prokaryotes?

bacteria (prokaryotes) are unicellular and are covered by a cell wall. just within the cell wall is the cell membrane. bacteria are prokaryotes, they do not have a nucleus. they do have dna. the extra space in the cell is filled with a fluid called cytoplasm. floating throughout the cytoplasm are ribosomes. ribosomes make proteins for the cell.

1. what surrounds all prokaryotic cells?
2. what two structures are found inside the prokaryotic cell?
3. what do ribosomes make?
4. how many cells are all prokaryotic organisms?

Explanation:

1. Analyze the text to find common characteristics of prokaryotes. It mentions DNA, ribosomes, cell - membrane, and cell - wall.
2. The text clearly states that bacteria are prokaryotes.
3. Prokaryotes lack a nucleus as stated.
4. The text says prokaryotic cells are surrounded by a cell membrane and an outer cell wall.
5. Inside the prokaryotic cell, DNA and ribosomes are found.
6. Ribosomes make proteins for the cell.
7. All prokaryotic organisms are unicellular.

Answer:

1. DNA, ribosomes, cell membrane, cell wall
2. Bacteria
3. Nucleus
4. Cell membrane and cell wall
5. DNA, ribosomes
6. Proteins
7. One (unicellular)
