Which of the following are true, when tracking transport of materials throughout a plant? Oxygen enters the Stomata, diffuses through the spongy tissue until it enters the palliade tissue cells Carbon dioxide enters the stomata, diffuses through the spongy tissue until it enters the pallisade tissue cells Water travels up the Xylem, and enters the pallisade tissue cells Water travels up the Phloem, and enters the pallisade tissue cells Photosynthesis occurs Cellular respiration occurs Oxygen diffuses out of the pallisade, the spongy tissue, and then exits through the stomata Carbon dioxide diffuses out of the pallisade, the spongy tissue, and then exits through the stomata Glucose travels down the Xylem, to all parts of the plant Glucose travels down the Phloem, to all parts of the plant G

Let's evaluate each statement to determine its validity regarding the transport of materials within a plant: 1. **Oxygen enters the Stomata, diffuses through the spongy tissue until it enters the palliade tissue cells** **False**: Oxygen is a *product* of photosynthesis and typically *exits* the leaf through the stomata, not enters. 2. **Carbon dioxide enters the stomata, diffuses through the spongy tissue until it enters the pallisade tissue cells** **True**: Carbon dioxide enters the leaf through the stomata and diffuses to the palisade mesophyll cells where photosynthesis occurs. 3. **Water travels up the Xylem, and enters the pallisade tissue cells** **True**: Water is transported from the roots to the leaves via the xylem and can enter palisade cells to support physiological processes. 4. **Water travels up the Phloem, and enters the pallisade tissue cells** **False**: While phloem primarily transports sugars and other organic nutrients, water transport is mainly handled by the xylem. 5. **Photosynthesis occurs** **True**: Photosynthesis takes place in the palisade and spongy mesophyll cells of the leaves. 6. **Cellular respiration occurs** **True**: Cellular respiration occurs in all living plant cells to produce energy. 7. **Oxygen diffuses out of the pallisade, the spongy tissue, and then exits through the stomata** **True**: Oxygen produced during photosynthesis diffuses from the palisade and spongy mesophyll cells out through the stomata. 8. **Carbon dioxide diffuses out of the pallisade, the spongy tissue, and then exits through the stomata** **False**: While some CO₂ is released from cellular respiration, the primary movement of CO₂ is into the leaf for photosynthesis. 9. **Glucose travels down the Xylem, to all parts of the plant** **False**: Glucose is transported via the phloem, not the xylem. 10. **Glucose travels down the Phloem, to all parts of the plant** **True**: The phloem transports glucose and other sugars from the leaves to various parts of the plant. **Summary of True Statements:** - **2. Carbon dioxide enters the stomata, diffuses through the spongy tissue until it enters the pallisade tissue cells** - **3. Water travels up the Xylem, and enters the pallisade tissue cells** - **5. Photosynthesis occurs** - **6. Cellular respiration occurs** - **7. Oxygen diffuses out of the pallisade, the spongy tissue, and then exits through the stomata** - **10. Glucose travels down the Phloem, to all parts of the plant**
