Question 11

A technician records observations of two cell types from a sample. A student concludes that cell P is bacterial because it has a cell wall, and that cell Q is not bacterial because it contains ribosomes.

CellObservation
PDNA enclosed in a nucleus; cell wall made of cellulose; ribosomes in the cytoplasm
QDNA lies free in the cytoplasm; cell wall not made of cellulose; ribosomes in the cytoplasm

Explain which cell is bacterial and why the student's conclusions are incorrect.
