Cells that are involved with the production of proteins are usually crowded with __________, which are small grainlike bodies composed of RNA and protein. A. lysosomes B. vacuoles C. plastids D. ribosomes
Well... a. lysosomes - "an organelle in the cytoplasm of eukaryotic cells containing degradative enzymes enclosed in a membrane." < http://4.bp.blogspot.com/-WjPuBU-62MQ/TmydFncTnLI/AAAAAAAAABQ/h0eLVUeGeRY/s1600/lysosomes.jpg > b. vacuoles - "a space or vesicle within the cytoplasm of a cell, enclosed by a membrane and typically containing fluid." < http://upload.wikimedia.org/wikipedia/commons/thumb/e/e0/Biological_cell_vacuole.svg/1466px-Biological_cell_vacuole.svg.png > c. plastids - "any of a class of small organelles, such as chloroplasts, in the cytoplasm of plant cells, containing pigment or food." d. ribosomes - "a minute particle consisting of RNA and associated proteins, found in large numbers in the cytoplasm of living cells. They bind messenger RNA and transfer RNA to synthesize polypeptides and proteins." < http://www.ftexploring.com/biology/life-images/prokaryote_cell.jpg >
