Morphology
astrocyte = astro + cyte
The word is built from specialized scientific combining forms, so an average B1 learner is unlikely to infer the meaning from the parts without prior exposure.
Etymology
Astrocyte comes from the parts astro- meaning 'star' and -cyte meaning 'cell', like the astro- in astronomy. That's why an astrocyte is a star-shaped cell that helps and protects nerve cells in the brain and spinal cord.
