Why some scientists do not consider ribosomes to be cell organelles?
Because they lack a membrane.
Which organelle in the plant leaf cell lacks a membrane?
Ribosomes are the organelles in a plant leaf cell that lack a membrane. Ribosomes are responsible for protein synthesis and can be found free-floating in the cytoplasm or attached to the endoplasmic reticulum.
Two membrane less cell organelles are?
Two membrane-less cell organelles are ribosomes and the nucleolus. Ribosomes are involved in protein synthesis, while the nucleolus is responsible for producing ribosomal RNA and assembling ribosomal subunits. Both organelles lack a membrane and are essential for cell function.
Infer why some scientists do not consider ribosomes to be cell organelles?
Some scientists do not consider ribosomes to be organelles because they lack a membrane that surrounds them, a defining characteristic of organelles. Instead, ribosomes are made up of RNA and protein molecules and are found floating freely in the cytoplasm or attached to the endoplasmic reticulum. They are essential for protein synthesis but are not considered organelles by all scientists.
Which type of cell has a plasma membrane ribosomes and nucleoid region?
A prokaryotic cell typically has a plasma membrane, ribosomes, and a nucleoid region. The nucleoid region contains genetic material in the form of a circular chromosome, and prokaryotic cells lack a membrane-bound nucleus.
Which organelles are not surounded by a membrane?
The ribosome is an organelle that is not surrounded by a membrane.
What is the role of the membrane in the rough endoplasmic reticulum?
The membrane of the RER contains ribosomes. This is what makes the membrane "rough". The function of the ribosomes is to produce proteins.
Do all organelles have a membrane?
None of the organelles have membrane.young chek
Do viruses have a nuclear membrane a cell wall membrane-bound organelles or ribosomes?
No, viruses do not have membrane bound organalles
why viruses are acellur?
Viruses are acellular, which means they don't have a cellular structure. As a result, they lack the majority of cell components such as organelles, ribosomes, and the plasma membrane.
Because bacteria are living cells which of the following should all bacteria be expected to have?
A Semipermeable cell membrane. Apex- T.F.
What organelle that does not contain a membrane?
Ribosomes
