Different proteins are produced on free-floating ribosomes than on ones attached to the rough endoplasmic reticulum (ER). In a general sense, proteins that will be used at the ER will be produced on attached ribosomes. Proteins that are meant for secretion will be made on free-floating ribosomes.
Agranular ER is attached to granular ER at all times. As granular ER is involved in making membrane and secreting proteins, and agranular ER is involved in making lipids and steroids, the percentage will differ according to the function of the cell.
Organelle which is the word used to describe the parts of cells with specific function as they act like mini organs.
Some ribosomes can be found floating free in the cytoplasm, while others are bound to the rough endoplasmic reticulum. (The name "rough" actually indicates the presence of ribosomes, against the "smooth" appearance of the smooth endoplasmic reticulum, which lacks ribosomes). There are several types of ribosomes,(rRNA = ribosomal RNA, mRNA = messenger RNA, tRNA = transfer RNA), all of which has its distinct job in the synthesizing process of protein. Information of regarding this process can be found on http://en.wikipedia.org/wiki/Protein_synthesis Ribosomes are considered "non-membranous organelles", as they differ from other organelles which are membrane-bound.
if you meant how they differ, its like this. Rough endoplasmic reticulum has ribosomes on it, these are responsible for proten synthesis. The smooth ER on the other hand does not have ribosomes
only eukaryotic cell has organelles
They are not covered by a membrane.
False. Ribosomes are not membrane-bound organelles. They are small, complex structures responsible for protein synthesis within the cell. They can be found free-floating in the cytoplasm or attached to the endoplasmic reticulum.
unlike most organelles ribosomes are not covered by membranes
Ribosomes are amongst the smallest organelles in a cell with a size of about 20 nanometers. Despite its small size compared to other organelles, it constitutes of complex and large molecules of RNA and proteins, which play vital roles in the process of protein synthesis. These complex RNA and proteins are collectively referred to as ribonucleic proteins.Ribosomes are present in all the living cells including both prokaryotes and eukaryotes. However, prokaryotic and eukaryotic ribosomes differ structurally with each other. Prokaryotic ribosomes are 70S while eukaryotic ribosomes are 80S. Ribosomes are predominantly found attached to RER (rough endoplasmic reticulum) and rarely as free organelles in the cytoplasm. However, the attachment of ribosomes with RER is not permanent since the attachment is in a state of attached and detached with RER surface.

Free ribosomes are located in the cytoplasm and synthesize proteins that remain within the cell, while attached ribosomes are bound to the endoplasmic reticulum and synthesize proteins that are either incorporated into cell membranes or exported from the cell. Both types of ribosomes carry out protein synthesis, but their location and functions differ.
how do ribosomes differ from other cell structures found found the cytoplasm?
Eukaryotic cells can differ from each other in terms of size, shape, function, and the organelles they contain. Different eukaryotic cells have specialized structures that enable them to perform specific functions. Additionally, eukaryotic cells can vary in the number and arrangement of organelles, impacting their overall structure and capabilities.
Endoplasmic Reticulum (ER) is a network of intracellular membranes, it links the plasma membrane and other membraneous organelles. it is involved in the production, processing, transport and storage of materials within a cell.Rough Endoplasmic Reticulum (RER), is assosisated with ribosomes, where proteins are made.Smooth endoplasmic reticulum(SER), lacks ribosomes and is involved in the metabolism of certain compounds and synthesis of lipids.
Mold spores are replete with organelles which is a complex of cellular structure. The nucleus is the most conspicuous organelles. It contains the DNA and has the function of reproduction. In prokaryotic spores the DNA is free in their cytoplasma.
Agranular ER is attached to granular ER at all times. As granular ER is involved in making membrane and secreting proteins, and agranular ER is involved in making lipids and steroids, the percentage will differ according to the function of the cell.
one is a ribosome and one is a dna
