Plant root cells lack chloroplasts but have mitochondria Steps: - Identify key structures in plant cells: cell walls, large vacuoles, mitochondria, and nuclei are present; chloroplasts are absent in roots due to no photosynthesis. - Examine choices for patterns matching root cell features: expect ✓ for universal organelles like mitochondria, x for light-dependent ones like chloroplasts. - Compare rows to typical root cell inventory: roots have energy production via mitochondria but no photosynthetic or animal-specific structures. - Select row aligning with plant root specifics: x for absent, ✓ for present in non-photosynthetic cells. Why B is correct: - Row B (x ✓ x x) matches roots having mitochondria (second ✓) but lacking chloroplasts, flagella, and centrioles, per eukaryotic plant cell definitions excluding photosynthetic and motile/animal features. Why the others are wrong: - A includes extra ✓ for cell wall but wrongly marks chloroplast present, violating root non-photosynthetic law. - C wrongly places ✓ on flagella and another absent structure, as plants lack motility organelles. - D duplicates C's errors, marking two non-plant root features present.
