Yes it has two parts. One is big and other is small.
There are several organelle.Most distinct organelle is ribosome

Yes they are organelles. They are in every cells.
Ribosomes are not membrane bound, they are free cytoplasmic organelles responsible for the translation of cytoplasmic mRNA's. When a ribosome begins to synthesize proteins that are needed in some organelles, the ribosome making this protein can become "membrane-bound". In eukaryotic cells this happens in a region of the endoplasmic reticulum (ER) called the "rough ER". The newly produced polypeptide chains are inserted directly into the ER by the ribosome and are then transported to their destinations. Ribosome in eukaryotes are called 80S ribosomes and consist of a small 40S subunit and a larger 60S subunit. Prokaryotes have 70S ribosomes consisting of a 30S and 50S subunits. Hope this helps.
Ribosomes produce proteins and proteins are produced very quickly. There are two kinds of ribosomes: Bound and Free The second organelle is the nucleolus where RNA is synthesized and assembled from proteins. Both are part of the nucleus which is part of the ER system
Ribosomes are the organelles that read coded genetic messages. Ribosomes can be found in all living cells.
