Growth is rapid in lag phase.

Answer

**Step-by-Step Solution:**

1. **Understanding the Phases of Growth:**
- Plant growth is typically represented in a graph with time on the x-axis and growth on the y-axis. The growth curve consists of several distinct phases: lag phase, log phase, and stationary phase.

2. **Identifying the Lag Phase:**
- The lag phase, also known as the initial slow growth phase, is the first phase of growth. During this phase, the growth rate is minimal. This is because the plant cells are adjusting to their environment and preparing for growth.

3. **Clarifying the Nature of Growth in the Lag Phase:**
- In the lag phase, the growth is not rapid; instead, it is characterized by slow and gradual growth. The cells are metabolically active but are primarily focused on adapting rather than growing significantly.

4. **Transition to the Log Phase:**
- After the lag phase, the plant enters the log phase (or exponential phase), where growth becomes rapid. This is the phase where the plant experiences its most significant increase in size and biomass.

5. **Conclusion:**
- Therefore, the statement "growth is rapid in the lag phase" is incorrect. The rapid growth occurs in the log phase, not the lag phase.
