Answer

To answer the question "Cellular plants" and "Vascular plants" are the groups created by, we can follow these steps:

### Step-by-Step Solution:

1. **Define Cellular Plants**:
- Cellular plants refer to plants that are primarily composed of simple cellular structures. They do not have specialized tissues for transporting water and nutrients.
- Examples include groups like Thallophyta (algae), Bryophyta (mosses and liverworts), and Pteridophyta (ferns).

2. **Define Vascular Plants**:
- Vascular plants are those that possess specialized tissues known as xylem and phloem, which are responsible for the transport of water, nutrients, and food throughout the plant.
- This group includes Gymnosperms (like conifers) and Angiosperms (flowering plants).

3. **Classification Basis**:
- The classification into cellular and vascular plants is based on the presence or absence of vascular tissues.
- Cellular plants are non-vascular, while vascular plants have well-defined vascular systems.

4. **Creator of the Classification**:
- The groups "Cellular plants" and "Vascular plants" were created by the botanist **D. Candolle**. He contributed significantly to the classification of plants based on their structural characteristics.

5. **Conclusion**:
- Therefore, the answer to the question is that "Cellular plants" and "Vascular plants" are groups created by D. Candolle.
