Ethane is a molecule that can also be categorized as a hydrocarbon, as it contains only 2 fundamental elements, carbon and hydrogen.
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.

Answer:
Myofibrils.
Explanation:
Myofibrils may be defined as the basic unit of muscle cell that are rod like in appearances. The tubular like myocetes or muscle cells are present in the myofibrils.
Myofibrils consists of dark and light bands. The myofibril is the skeletal muscle organelle that actually contracts during the muscle contraction. The myofibril unit is formed during the embryonic development by the myogenesis process.
Thus, the correct answer is option (E).
Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma.
