Correct option is A
The correct answer is: (A) air space between soil particles
- Plant roots take up oxygen from the air spaces between soil particles.
- These air spaces contain oxygen that is necessary for cellular respiration in the root cells, enabling them to generate energy.
- The oxygen from the soil air is absorbed through tiny pores in the root called root hairs.
Other option Explanation:
- Cytoplasm: Oxygen is used within the cytoplasm, but not absorbed from it.
- Stomata: Found on leaves, not roots, and responsible for gas exchange in aerial parts.
- Water: Water provides nutrients but not the primary source of oxygen for root respiration.
