Four Adaptations for Life on Land
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Early land plants evolved key adaptations to life on land: the haplodiplontic cycle of Bio 1001, apical meristem tissue, a waxy cuticle, and lignified cell walls.
Show
A moss's waxy cuticle resists drying; lignin stiffens cell walls in later lineages.
Watch for
Not every land plant shows all four — mosses lack lignin, and losing one does not remove a lineage from the group.
