The correct Answer is:
To determine the group of plants that fits the given description, we can follow these steps: ### Step 1: Analyze the Description The description states that the plants have no roots, flowers, or seeds. This indicates that we are looking for a group of plants that does not possess these characteristics. ### Step 2: Eliminate Groups of Plants - **Angiosperms**: These are flowering plants that produce seeds. Since the description specifies no flowers and no seeds, angiosperms can be eliminated. - **Gymnosperms**: These plants also produce seeds and typically have roots. Therefore, gymnosperms can be eliminated as well. - **Pteridophytes (ferns)**: These plants have roots and reproduce via spores, so they do not fit the description either. ### Step 3: Identify the Remaining Group The only group left is **Bryophytes**. Bryophytes are non-vascular plants that include mosses and liverworts. They typically do not have true roots, flowers, or seeds. ### Step 4: Confirm Characteristics of Bryophytes - **Plant Body**: Bryophytes have a plant body that can be characterized by a forked shoot or a ribbon-like green thallus. - **Reproductive Structures**: They possess archegonia as their female reproductive organ. ### Conclusion Based on the analysis, the group of plants that fits the description provided is **Bryophytes**. ---
