Answer 1

Here are the answers with brief explanations:

1) Angiosperms are grouped into monocots and dicots.
- Angiosperms (flowering plants) are commonly divided into monocots and dicots (eudicots).

2) Mosses are seedless plants.
- Mosses (bryophytes) are nonvascular and reproduce via spores, not seeds, flowers, or fruit.

3) Gymnosperms are the first seed plants.
- Gymnosperms were the first plants to evolve seeds (but not flowers).

4) Gymnosperms.
- Exposed seeds on cone-like structures are characteristic of gymnosperms.

5) Vascular tissue and seeds.
- Vascular tissue allowed plants to grow larger and transport water/nutrients; seeds protected and aided dispersal of embryos.
