Answer:
when water flow through the canyon the water caused erosion
Explanation:
As the cell contains activated genes for the production of mitochondria, chloroplasts and a cell wall and inactive genes for root hair production, then it is a leaf cell.
- Leaf cells are different from other parts of the plant as they carry out photosynthesis for the preparation of food for plants.
- The chloroplasts present in leaves contain chlorophyll that helps in photosynthesis in the presence of sunlight using water and carbon dioxide. In this process, oxygen is released.
- Leaf cells contain many active and inactive genes.
- Leaf cells contain active genes for the formation of mitochondria, chloroplasts and a cell wall.
- Root cells contain the active genes for the formation of root hairs. But, chloroplasts are absent in root hairs as they do not have any role in photosynthesis. Roots are present inside the soil.
Thus, the leaf cell is the correct option as plant cells contain a cell wall and the leaf helps in the photosynthesis process.
