The reason plants are considered totipotent is:
Correct answer: D. Both A and B
- A. Each cell has full genetic potential of the organism
- B. A single cell could become a complete plant
- C. Because they have lesser potential for tissue culturing
- D. Both A and B
Explanation
Each cell has the full genetic potential of the organism, and a single cell could become a complete plant. The term "totipotent" means that a single cell has the ability to regenerate an entire plant. This is possible because each plant cell contains the full genetic potential of the organism. This means that under the right conditions, a single cell can be stimulated to divide and differentiate into all of the different cell types that make up the plant.
