A bacterial cell contains about 10,000 ribosomes which co up to 30% of the weight of the bacterium.
In contrast to most eukaryote ribosomes, the bacterial ribosomes do not appear to be attached to internal cell membranes, but are found free in the cytoplasm.
In functionally, active bacteria the cytoplasm is packed -with free and randomly distributed ribosomes.
This dense packing may mask any attachment to internal membranes.
Strings of ribosomes have been found loosely attached to the inside of the plasma membrane.

What organelles are unique to prokaryotic cells?
Prokaryotic cells have: 1.cell membrane, 2.cell wall, 3.gel capsule, 4.DNA loops, 5.cytoplasm, 6.ribosomes, 7.cillia or flgella. 8.Prokaryotic cells don't have nucleas.
Discuss evidence that supports the endosymbiotic theory of eukaryotic evolution?
1.) Mitochondria and plastids are relatively the same size as bacteria 2.) Mitochondria and plastids have nucleiod DNA molecules - just like bacteria. 3.) Mitochondria and plastids reproduce the same way as bacteria - binary fission.
What would happen if an animal cell didn't have ribosomes?
Ribosomes are the organelles that build proteins within the cell. Without protein, the cell could not form structural units, transport any matter between the interior and exterior, or create enzymes. As a result the cell would die.
What are 4 things all cells have?
Cell membrane, DNA, cytoplasm and ribosomes
What is the outer most border in a bacteria cell called?
The outermost border in a bacteria cell is called membrane. This is also commonly referred to as the cell wall.
What is found in the cytoplasmof a bacteria cell?
DNA and ribosomes.
What organelles are there in a bacteria cell?
Ribosomes Cell membrane Cell wall Mitochondrion flagellum
Which organelle is found in both bacteria cell and plant cell?
Nucleus, mitochondria, and the ribosomes
In general bacteria consist a nucleus ribosomes and a cell wall?
No. No nucleus.
Which structures are possessed by all bacteria?
Chromosomes Cell Membrane Ribosomes
Does bacteria cell contain another bacteria?
No, bacteria can not endocytosise another bacteria. bacteria contains cell wall, DNA called nucleoid and cytoplasm. Bacteria can make its own proteins by its ribosomes..No, they do not. They are not large enough for more bacteria inside.
What organisms are prokaryote?
cytoplasm,ribosomes,cell wall,cell membrane
How does a bacteria cell differ from a plant or animal cell?
A bacteria cell differs structurally from plant and animal cells because of its small size. A bacteria cell has flagella outside of the cell to help it move. A bacteria cell does not contain organelles. Only the chromosome and sometimes ribosomes are visible in a bacteria cell.

Cell organelles that E. coli and other bacteria have in common with eukaryotes are?
ribosomes
What will you find in the cytoplasm of a bacteria cell?
The cell membrane is found in the cytoplasm of bacterial cells!! yeah...um...that's completely wrong... a cell membrane is found in eukaryotic organisms, not bacteria, and it surrounds the cytoplasm. bacteria have free floating (non-membrane bound) ribosomes, and most have circular chromosomes
Where in a bacterium are proteins synthesized?
Since bacteria do not contain a nucleus or a complex translation machinery, protein synthesis occurs on free ribosomes in the cytoplasm
