States that all organisms are made up of one or more cells.
What is the cell theory?
300
The organelle that makes proteins by putting together chains of amino acids using instructions encoded in the cell's DNA
What is a ribosome?
300
A microscopic network of protein filaments and tubules in the cytoplasm of many living cells, giving them shape and coherence.
