AI Generated Solution

The correct Answer is:
To determine whether the statement "In bryophytes, zygotes do not undergo reduction division immediately" is true or false, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Terms**: - **Zygote**: This is the fertilized egg that forms when two gametes (male and female) fuse. It is diploid (2n). - **Reduction Division**: This refers to meiosis, a type of cell division that reduces the chromosome number by half, resulting in haploid (n) cells. 2. **Identify the Process in Bryophytes**: - In bryophytes (which include mosses, liverworts, and hornworts), the life cycle includes a dominant gametophyte stage and a sporophyte stage. - The zygote in bryophytes develops into a sporophyte, which is initially attached to the gametophyte. 3. **Timing of Meiosis**: - In bryophytes, the zygote does not undergo meiosis (reduction division) immediately after fertilization. Instead, it develops into a sporophyte first. - The sporophyte eventually matures and then undergoes meiosis to produce spores, which are haploid. 4. **Conclusion**: - Since the zygote does not undergo reduction division immediately but rather develops into a sporophyte first, the statement is **True**. ### Final Answer: **True** ---
