- Water absorbed across
cell membrane

10. What is the ecological importance (historically - Photosynthesis con-
and presently) of green algae? tributes to increased bi-
ological production and
biodiversity in aquatic
ecosystems

11. All plant groups contribute to increased bio- a) food to consumers
diversity by providing resources: a)______, b) b) oxygen
_______, and c) _____ and c) habitat

12. Where do non-vascular plants inhabit? aquatic and terrestrial
ecosystems

13. What are the characteristics of non-vascular - Cells organized into tis-
plants? sues/organs
- Cuticle and stomata
- No vascular tissue
- Embryo released from
plant in a desiccation-re-
sistant spore

14. What is a waxy layer that prevents water loss Cuticle
from stems and leaves?

15. What has pores that allow gas to exchange in Stomata
photosynthetic tissues and guard cells close
under conditions of water stress (to reduce
further water loss)?

16. How do the cuticle and stomata acquire nutri- - Rhizoids anchor plant
ents and water? to substrate (e.g., soil,
wood, rock) and absorb
water, nutrients (N,P)
- Carbon dioxide ab-
sorbed through stomata

and presently) of seedless vascular plants? lignin enable plants to
grow tall and inhabit drier
habitats
- Increased terrestrial
plant abundance and di-
versity (habitat and food
resources) enables in-
creased biodiversity and
organism abundance
