Morphology
The noun phrase is directly compositional: 'columnar' means column-shaped and 'cell' is a biological unit, so a 'columnar cell' is immediately understood as a cell shaped like a column. This adjective + noun pattern is common and cross-linguistically transparent, so a B1 learner who knows both constituents can infer the meaning.
Etymology
Columnar cell comes from the word columnar, meaning like a column, and cell, meaning a small room, so picture many tall, thin columns standing side by side. That's why columnar cell means 'a long, pillar-shaped cell' in the body today.
