Cells that have no membrane-covered organelles are?
Many people think a Mitochondria does not have a membrane... but it does. The correct answer is - ribosomes (and only ribosomes, the rest of the organelles have a membrane surrounding them.)
Which organelles are surrounded by a membrane and which are not?
In mammalian cells, the mitochondra, lysosomes and peroxisomes are ebveloped by a lipid containing membrant. None of the other orgenelles are membrane bound. In plants, the chloroplasts are bound by a membrane. None of the other orgenelles are covered by a membrane
Which organelles are not covered by A membrane?
As a general rule, practically all the internal organelles of a cell are covered by a protective membrane, except for one type, which couldn't even be called a real organelle, and those are the Ribosomes. More a macromolecular assemble than a cell organelle, the reason because they aren't membrane-bound is because they can directly interact with the membrane in order to exchange proteins, so, having their own membrane would actually act as a barrier for them to do their job correctly.
How are ribosome difference from other organelles?
unlike most organelles ribosomes are not covered by membranes
Rough ER is covered in ribosomes?
That's correct! Ribosomes on the rough endoplasmic reticulum (ER) are responsible for protein synthesis. The rough ER is involved in the synthesis and processing of proteins that are ultimately exported from the cell or used in the cell membrane.
What are the mitochondria?
are oval, membrane-covered organelles
Are ribosomes covered by membrane?
No,they are not covered.They are also in prokariyotes.

Are ribosomes a membrane covered organelle?
No, they are not. Neither prokaryotes like bacteria nor eukaryotes (like our cells) have membrane bound ribosomes.
How do ribosomes differ from other organelles in the cell?
They are not covered by a membrane.
Which organelles are NOT covered by membrane in the cell?
In a typical animal cell, the only major organelles not covered by membranes are the ribosomes. Ribosomes are composed of r-RNA and proteins.
Is mitochondria covered by a membrane?
no it is i dont know consult biology.com
Where are cell parts packaged?
Scientifically explaining, they are membrane-covered organelles that are found only in the eukaryotic cell. Prokaryotic cells do not have membrane-covered organelles. The only organelle they have, not membrane-covered, are ribosomes.
Is the mitochondria covered by a membrane?
Yes, the mitochondria is surrounded by a double membrane. The outer membrane is smooth, and the inner membrane is folded to form structures called cristae. This double membrane helps protect the contents of the mitochondria and regulate the flow of molecules in and out.
Does bacteria have a single membrane covered organelle?
No, bacteria do not have membrane-covered organelles. They lack membrane-bound organelles such as mitochondria, nucleus, and endoplasmic reticulum found in eukaryotic cells. Bacteria have a single cell membrane surrounding their cytoplasm.
What is the history of mashed potatoes?
The nucleus of the eukaryotic cells contains the DNA of the cell and the associated proteins that form the chromosomes, and is separated from the cytoplasm by a double porous membrane. The outer nuclear membrane has a complex internal structure, part of which is covered with ribosomes, i.e., protein and RNA containing bodies which are the sites of protein synthesis. In aerobic eukaryotes, chemical energy is trapped in the microchondria, organelles bounded by a double membrane and containing an internal membrane structure in which are found both the electron transport system and the enzymes associated with respiratory metabolism. Mitochondria are absent in anaerobic eukaryotes. In photosynthetic eukaryotes, i.e., green algae, an organelle similar to the mitochondrion, the chloroplast, is found. Both mitochondria and chloroplasts contain small circular DNA molecules similar to those found in prokaryotes, ribosomes and other components of protein synthesis.
