- Humans have a greater variety of internal and external structures.
- Acceptable responses may include, but are not limited to:
- Both are plants.
- Both are multicellular.
- Both perform photosynthesis.
- Vascular plants have phloem and xylem. Nonvascular plants do not.
- Nonvascular plants are very small.
- Vascular plants have roots, stems, and leaves. Nonvascular plants do not.
- Vascular plants have flowers and seed. Nonvascular plants have spores.
- Acceptable responses may include, but are not limited to:
- Vascular plants have a complicated system to transport food and water throughout the plant.
- Vascular plants have root systems to gather water from the ground. Nonvascular plants get water through osmosis.
- Vascular plants can live in many areas with very different climates. Nonvascular plants need to be in moist areas.
