Cellular totipotency is

Options

A. A. capability of plant cells to form complete plant
B. B. formation of a new species
C. C. formation of a new plant
D. D. synthesis of new cell

Explanation

**Step-by-Step Solution:**

1. **Understanding Cellular Totipotency:**
- Cellular totipotency refers to the ability of a single cell to develop into a complete organism. In plants, this means that a single plant cell can differentiate into all types of cells necessary to form a complete plant.

2. **Defining the Concept:**
- The definition of cellular totipotency is: "It is the ability of a single cell to differentiate into all types of cells and organize them to form a complete new plant."

3. **Identifying the Context:**
- Cellular totipotency is primarily observed in plant cells, though it can also occur in some animal cells. This ability is crucial for processes like regeneration and cloning in plants.

4. **Genetic Information Requirement:**
- For cellular totipotency to occur, the cell must possess complete genetic information. This ensures that the cell has all the necessary instructions to develop into various cell types and ultimately form a complete organism.

5. **Evaluating the Options:**
- Given the options:
A. Capability of plant cells to form complete plant
B. Formation of new species
C. Formation of new plant
D. Synthesis of new cell
- Option A aligns with the definition of cellular totipotency, as it specifically mentions the capability of plant cells to form a complete plant.

6. **Conclusion:**
- Therefore, the correct answer to the question "Cellular totipotency is" is **A. Capability of plant cells to form complete plant**.
