WebA ribosome is a cellular structure not bounded by a membrane, composed of ribosomal RNA and proteins, and whose function is to synthesize proteins. The ribosome’s … WebEndoplasmic reticulum is an organelle found in both eukaryotic animal and plant cells. It often appears as two interconnected sub-compartments, namely rough ER and smooth ER. Both types consist of membrane enclosed, interconnected flattened tubes. The rough ER, studded with millions of membrane bound ribosomes, is involved with the production ...
