Some plant groups exhibit intermediate condition w.r.t life cycle pattern. Which characteristic will not be exhibited by such kind of plant?

Options

A. Haplodiplontic life cycle pattern
B. Both phases are multicellular and often free living
C. They can differ in dominant phase
D. Meiosis takes place in zygote

Answer

To solve the question regarding the characteristics exhibited by plant groups that show an intermediate life cycle pattern, we need to analyze the life cycle patterns of plants, particularly focusing on the haplodiplotic life cycle.

### Step-by-Step Solution:

1. **Understanding Life Cycle Patterns**:
- Plants exhibit different life cycle patterns: haplontic, diplontic, and haplodiplotic.
- Haplontic: The dominant phase is haploid (gametophyte), and the sporophyte is short-lived.
- Diplontic: The dominant phase is diploid (sporophyte), and gametophytes are reduced and often dependent.
- Haplodiplotic: Both haploid and diploid phases are multicellular and can be free-living.

2. **Characteristics of Haplodiplotic Life Cycle**:
- In the haplodiplotic life cycle, both the sporophyte (diploid) and gametophyte (haploid) phases are multicellular.
- The sporophyte produces spores through meiosis, which are haploid.
- Spores germinate to form gametophytes that produce gametes.

3. **Identifying the Incorrect Characteristic**:
- The question asks which characteristic will **not** be exhibited by plants with an intermediate life cycle pattern.
- The statement "meiosis takes place in zygote" is incorrect because meiosis occurs in the sporophyte, not in the zygote. The zygote is formed from the fusion of gametes and is diploid.

4. **Conclusion**:
- Therefore, the characteristic that will not be exhibited by plants with an intermediate life cycle pattern is that "meiosis takes place in zygote".

### Final Answer:
The characteristic that will not be exhibited by plants with an intermediate life cycle pattern is: **"meiosis takes place in zygote."**
