STUDY
PLAY
Which is the closest, extant relative of modern day true plants?
Protista
Which came first, aquatic plants are true plants?
Aquatic plants
Differences between aquatic vs terrestrial habitats of plants
Hydrostatic pressure vs physical support
Uniform water availability vs localized water availability
Uniform nutrient availability vs localized nutrient
Stratified light layers vs unstratified light layers
Both have uniform oxygen and carbon dioxide
What is the biggest stressor of terrestrial life vs aquatic life?
desiccation
Coping mechanisms developed by terrestrial plants (6)
Specialized cells
vascularity
roots or rhizoids
waxy cuticle
stomata
apical meristem
What are the different specialized cells
sclerenchyma
collenchyma
sporopollenin
Scelerenchyma
Has thick inner cell walls
Dead at maturity
Collenchyma
Has thick outer cell walls
Not dead at maturity
Sporopollenin
Protein that reinforces walls of pores
Which stressor of terrestrial life do sclerenchyma, collenchyma, and sporollenin allow them to cope with?
Structural support and desiccation
rhizoids
wannabe roots
Almost no absorption capabilities
Only for anchorage
What stressor of terrestrial life might have vessels and true root help plants to cope with?
Desiccation
Localization of nutrients
Transportation of nutrients
What stressor of terrestrial life might have waxy cuticles and stomata help plants to cope with?
