Morphology

microsphere = sphere (transparent) = micro + sphere

The meaning is directly compositional: 'micro-' means very small and 'sphere' means a round particle.

Etymology

The word microsphere combines micro- ('small') and sphere ('ball' or 'round object'), the same micro- you see in microscope. So a microsphere is literally a 'small ball', which explains why it means a very small round particle used in science and medicine.
