Answer: Lysosomes synthesize proteins from the recycled amino acids.
Explanation:
This is a cell organelle with a spherical sac shape, bounded by a single membrane.( Unlike chloroplast and mitochondrial which  double membranes.) It contain digestive enzymes which is hydrolytic in nature, this splits molecules by addition of water molecules. The digestive enzymes are separated from other cell organelles because of autolysis/autophagic which is automatic discharge of digestive enzymes in a contained cell which destroy the whole cell.
T<u>hey  release  vesicles  containing the enzymes towards the target structure,and the  vesicle  fused with the membrane of the target cell to discharged the hydrolytic  enzymes for digestion</u>
They breakdown old and worn out cells organelles, or the whole cell (for example the breakdown of mammary glands after lactation. Lysosomes are also used to digest bacterial in white blood cells by ENDOCYTOSIS. 
Note: RIBOSOMES  play a role in protein Synthesis not LYSOSOMES.
Their average size is 0.1-0.5µm in diameter
