Embryo is present but true vasculature is absent in the group :-

Options

A. Cyanophyta
B. Tracheophyta
C. Bryophyta
D. Chlorophyta

Answer

To solve the question "Embryo is present but true vasculature is absent in the group," we need to analyze the options provided: Sinophyta, Tracheophyta, Bryophyta, and Chlorophyta.

### Step-by-Step Solution:

1. **Understand the Groups**:
- **Sinophyta**: This group typically refers to cyanobacteria, which are photosynthetic bacteria and do not have true vascular tissues.
- **Tracheophyta**: This group includes vascular plants that have true vascular tissues (xylem and phloem) for the transport of water and nutrients.
- **Bryophyta**: This group includes mosses and liverworts, which are non-vascular plants. They have an embryo stage but lack true vascular tissues.
- **Chlorophyta**: This group refers to green algae, which can have a variety of structures but do not have true vascular tissues.

2. **Identify the Key Features**:
- The question specifies that an embryo is present but true vasculature is absent.
- True vasculature refers to the presence of xylem and phloem, which are absent in non-vascular plants.

3. **Analyze Each Option**:
- **Sinophyta**: While they lack vascular tissues, they do not have an embryo as defined in the context of plant development.
- **Tracheophyta**: They have true vascular tissues and also develop embryos, so they do not fit the criteria.
- **Bryophyta**: They have an embryo (the sporophyte generation develops from the zygote) and lack true vascular tissues.
- **Chlorophyta**: They may have reproductive structures but do not typically develop an embryo in the same way as Bryophyta.

4. **Conclusion**:
- The only group that fits the description of having an embryo but lacking true vascular tissues is **Bryophyta**.

Thus, the correct answer is **Bryophyta (Option C)**.
