Plant cell do have ribosomes and they are composed of proteins and ribosomal RNA. The ribosomes in a plant cell are found in the cytoplasm, the surface of the rough endoplasmic reticulum, the mitochondria and on chloroplasts. There are two types of ribosomes - free ribsomes and attached ribosomes.
Ribosomes are found in the cytoplasm of a cell. They are either free floating or bound to the endoplasmic reticulum. Groups of ribosomes stuck together are called polysomes. Most cells contain thousands of ribosomes, while a few specialized cells contain millions. Brain cells and the cells of the pancreas contain large concentrations of ribosomes since they produce a large amount of protein. slide 2 of 6. The Structure of Ribosomes Although ribosomes are called organelles, they don't have a membrane that holds the contents of the ribosome in one cohesive structure. Ribosomes are composed of ribosomal RNA (rRNA) and protein. Sixty percent of the structure is rRNA and 40 percent is protein. There are two subunits: a large subunit and a small subunit. They are labeled as 60s and 40s after the Svedberg values. The subunits of ribosomes are produced in the nucleolus, which is located in the nucleus of the cell. Ribosomal proteins enter the nucleolus and combine with four rRNA strands to produce the two subunits. The subunits leave the nucleus through the nuclear pores and combine in the cytoplasm.
