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.

Cell is the structural and functional unit of life. It has various components that are important for its survival such as plasma membrane, mitochondria, endoplasmic membrane, nucleus, golgi body, etc.
Answer: At a minimum, for a cell to be alive, it must contain the following organelles:
1. Plasma membrane: It is the covering of the cell that is selectively permeable.
2. Nucleus: It contains genetic material which is important for DNA replication.
3. Mitochondria: It is the power house of the cell that synthesizes ATP.
Sulforhodamine B (SRB) cell cytotoxicity assay has been widely used for drug toxicity screening and cell proliferation detection.

Answer:
0 meters
Explanation:
When we talk about displacement, think that the think of it as the measure of the distance between the starting point of the object, from its end point.
Since we are talking about a lap around a track, it would mean that the starting point is also the end point. So if you started and end at the same point, the distance between it would be 0.
