C , The Answer Is C , They Are NOT Inclosed By A Membrane !
unlike most organelles ribosomes are not covered by membranes
Ribosomes, if you want to count them. Next I think is the lysosomes.
well, the various organelles are within the cell, surrounded by the gel like cytoplasm. There are protein structures called mircotubles and mircofilaments which at like the cell's skeletal structure
Ribosomes are the organelles responsible for producing proteins in a cell. They can be found in the cytoplasm or attached to the endoplasmic reticulum. Ribosomes read the instructions in messenger RNA and synthesize proteins by linking together amino acids in a specific order.
External structures of a prokaryotic cell include glycocalyces, flagella, fimbriae, and pili. Most prokaryotic cells have a cell wall. Prokaryotic cells have a cytoplasmic membrane, cytosol, and inclusions. The nonmembranous organelles found in a prokaryotic cell are ribosomes and the cytoskeleton.
The most numerous of the cell's organelles are ribosomes. These small structures are essential for protein synthesis, translating messenger RNA (mRNA) into polypeptide chains. Ribosomes can be found either freely floating in the cytoplasm or attached to the endoplasmic reticulum, forming rough ER. Their abundance reflects the high demand for proteins necessary for various cellular functions.
The ribosomes are the organelles most directly involved in protein synthesis, as they are the site where translation (the process of converting mRNA sequences into proteins) occurs. Ribosomes can be found both free-floating in the cytoplasm or attached to the endoplasmic reticulum.
Not all cells have true organelles. prokaryotic cells (bacteria, for example) have no true nucleus and have ribosomes, which are not membrane-bound. eukaryotic cells do have true organelles. they make up the world of life you can see (plants, animals, most fungi)
animal cells are Eukaryotic cells, so they have a true nucleus, and organelles such as mitochondaria, Golgi apparatus, Endoplasmic reticulum, cell membrane, ribosomes, vesicles, lysosomes and obviously the nucleus. That's most of them i think, the most important anyway
Well... the cell! Most organelles (Mitochondria, some ribosomes, lysosomes, chloroplasts, centrosomes, golgi apparatus) appear to float freely in the cytoplasm (although on a more advanced level the are attached to the cytoskeleton), whereas others are attached to each other - for example the rough ER had hundreds of ribosomes attached to it, and is itself attached to the nuclear envelope!
Most of the cell's activities take place in the cytoplasm, where organelles like the mitochondria, endoplasmic reticulum, and ribosomes work together to carry out processes such as protein synthesis, energy production, and waste elimination.
In general, every cell has cytoplasm and a cell membrane. Most have a nuclear region and ribosomes as well. More advanced cells have various other organelles plus all the above.
