What else can I help you with?
Do they have mitochondria characteristic of anaerobic species?
Yes they have. They have 70s ribosomes and circular DNA
What characteristic of chloroplasts that suggest that they might have evolved from free living bacteria?
They can replicate themselves. They have circular DNA. They also have 70s ribosomes
Which is not a characteristic of ribosomes A they are made of DNA B the make proteins from amino acids C they float in the cell D they interpret instructions in genes?
A characteristic that is not true for ribosomes is A: they are made of DNA. Ribosomes are primarily composed of ribosomal RNA (rRNA) and proteins, not DNA. They function to synthesize proteins from amino acids and are found floating freely in the cytoplasm or attached to the endoplasmic reticulum, interpreting instructions from messenger RNA (mRNA) derived from genes.
Ich group would you place a unicellular organism that has 70s ribosomes and a peptidoglycan cell wall?
I would place this unicellular organism in the domain Bacteria. The presence of 70s ribosomes and a peptidoglycan cell wall are characteristic features of bacteria.
What tiny organelles are attached to the ER?
ribosomes
Do they have mitochondria characteristic of anaerobic species?
Yes they have. They have 70s ribosomes and circular DNA
How do ER with ribosomes look under a microscope?
Under a microscope, the endoplasmic reticulum (ER) with ribosomes appears as a rough, grainy appearance due to the presence of ribosomes on its surface. This rough appearance distinguishes it from smooth ER, which lacks ribosomes. The ribosomes on the rough ER are involved in protein synthesis, giving the ER its characteristic appearance.
What characteristic of chloroplasts that suggest that they might have evolved from free living bacteria?
They can replicate themselves. They have circular DNA. They also have 70s ribosomes
What does rough endoplasmic reticulum have embedded on its surface?
Ribosomes are embedded on the surface of rough endoplasmic reticulum. These ribosomes are responsible for protein synthesis, and their presence gives the rough endoplasmic reticulum its characteristic bumpy appearance.
Do eubacteria contain ribosomes?
Yes, eubacteria do contain ribosomes.As in eukaryotic cells, the ribosomes are the sites of polypeptide synthesis.Like the ribosomes in other organisms, eubacterial ribosomes are constructed of RNA and proteins. However, the details of their chemical composition are different from those of the other major groups (eukaryotes and archaeobacteria) and are characteristic of eubacteria.The chemistry of the ribosomes in mitochondria and chloroplasts is like that of eubacteria.
Ich group would you place a unicellular organism that has 70s ribosomes and a peptidoglycan cell wall?
I would place this unicellular organism in the domain Bacteria. The presence of 70s ribosomes and a peptidoglycan cell wall are characteristic features of bacteria.
ER without ribosomes looks what under the microscope?
ER without ribosomes, known as smooth ER, appears smooth and lacks the characteristic dot-like appearance seen in rough ER. It is often associated with lipid synthesis and detoxification reactions in the cell.
Is the rough endoplasmic reticulum covered with ribosomes?
No, the name Rough Endoplasmic Reticulum comes from the 'rough' appearance when seen under an electron microscope. The 'rough' bits are ribosomes which stud the surface. Smooth Endoplasmic Reticulum has no 'rough' bits ie. no ribosomes.
What small structures are found attached to the rough endoplasmic reticulum?
Ribosomes are the small structures found attached to the rough endoplasmic reticulum. These ribosomes are responsible for protein synthesis within the cell and give the rough endoplasmic reticulum its characteristic rough appearance.
The sites of protein synthesis are?
Protein synthesis occurs at ribosomes, which can be found in the cytoplasm of a cell. In eukaryotic cells, proteins can also be synthesized on ribosomes located on the rough endoplasmic reticulum.
What tiny organelles are attached to the ER?
ribosomes
What are unattached ribosomes in the cytosol called?
Free ribosomes.
