What is thought to be the ancestor to terrestrial plants?
What is the support for this?
Multicellular and Eukaryotic
Cell walls made of Cellulose
Chlorophyll a and b
Store excess sugar as starch
Know the adaptations seen in plants for terrestrial life.
Muticellular dependent embryo (to give the offspring a better start)
Alternative of generation (ex: gametophyte ? sporophyte)
Walled spores produced in sporangia (protection)
Other adaption: Cuticle: waxy material to reduce water loss, Stomata: control water loss (gas exchange), Xylem: move water (allow plants to grow taller), Phloem: move food (allow plants to grow taller)
Secondary compounds: developing compounds that is toxic to protect the plant from the predators
