These float free in the cytoplasm and are the site for protein synthesis within the cell
A
Cytoplasm
B
Nucleus
C
mitochondria
D
Ribosomes
E
Endoplasmic reticulum
Explanation: 

Detailed explanation-1: -Ribosomes are non-membrane-bound cell structures that serve as protein synthesis sites. They have nearly equal amounts of protein and a type of ribonucleic acid known as rRNA (ribosomal RNA). Some ribosomes associate with the endoplasmic reticulum, while others float freely in the cytoplasm.

Detailed explanation-2: -Ribosomes float freely in the cytoplasm or sometimes bind to another organelle called the endoplasmic reticulum.

Detailed explanation-3: -Since there are no membrane-bound organelles in prokaryotes, the ribosomes float free in the cytosol. Ribosomes are found in many places around a eukaryotic cell. You might find them floating in the cytosol. Those floating ribosomes make proteins that will be used inside of the cell.

Detailed explanation-4: -Eukaryotic ribosomes may be either free, meaning that they are floating around in the cytoplasm, or bound, meaning that they are attached to the endoplasmic reticulum or the outside of the nuclear envelope.

Detailed explanation-5: -The process of protein synthesis occurs in ribosomes. Ribosomes are either floating freely in the cytoplasm or found attached to the endoplasmic reticulum.
