A botanist examines a cross-section of a plant leaf under a microscope and observes cells densely packed with structures responsible for converting light energy into chemical energy. Based on the provided diagram and text, what specific cellular components are these structures most likely to be?

  • A: Root hairs
  • B: Chloroplasts
  • C: Tube-shaped cells
  • D: Dermal tissue

Explanation

The section 'At the cellular level' states that 'Photosynthetic cells are packed with chloroplasts that convert sunlight into chemical energy.' This directly identifies chloroplasts as the structures responsible for this function.
