Eukaryotic ribosomes are 80S and composed of a small 40S subunit and a large 60S subunit. Prokaryotic ribosomes are 70S with 30S and 50S subunits. The S (Svedberg) value is a measure of sedimentation rate, not simply additive. Both ribosome types synthesize proteins, but the structural difference allows selective antibiotic targeting (e.g., streptomycin acts on 70S).
Explanation:
Anthocyanins are water-soluble vacuolar pigments that appear red, purple, or blue depending on pH. They are flavonoids. Chlorophyll is green, carotenoids yellow/orange, lycopene red.
