A scientist studies two plant structures.
| Structure | Observations |
|---|---|
| X | Made of many column-shaped cells. Each cell contains many chloroplasts and is close to the light. |
| Y | One layer covers and protects the structure. Another region carries out most of the photosynthesis. Veins transport water, mineral ions and dissolved sugars. |
Explain which structure is a tissue and which structure is an organ.
