Infer why liverworts often grow close to the ground and in areas with plenty of moisture
They have vascular tissue
True/False: Both lycophytes and pterophytes produce spores
True
Name 5 adaptations that help plants when moving from sea to land
- Cuticle-Prevents water evaporation and protects against microorganisms
- Stomata-enables the exchange of gas within and outside the cell
- Vascular tissue-transports water from soil to leaves
- Reproductive Strategies-produce with spores and gametophytes
- Seeds-reproduce with an embryo surrounded in a protective coating
