Answers (100% Pass)
What are the key characteristics of plants? - ✔️✔️- Composed of one or more eukaryote
cell(s)
- Cell wall composed of cellulose
- Chlorophyll in chloroplast
How do plants acquire energy? - ✔️✔️By autotrophy (photosynthesis)
How do plants acquire nutrients? - ✔️✔️Absorbed from the environment (Nitrogen and
Phosphorus)
How do plants produce ATP? - ✔️✔️Aerobic cellular respiration
What plant is an exception? Why? - ✔️✔️Ghost plants
- Lacks chlorophyll, and is parasitic on mycorrhizal fungi that have mutualistic associations
with trees
What are the 5 types of plant lineages? - ✔️✔️1. Green Algae
2. Nonvascular plants
3. Seedless vascular plants
4. Gymnosperms
5. Angiosperms
Where do green algae inhabit? - ✔️✔️aquatic ecosystems
What are the characteristics of green algae? - ✔️✔️- Unicellular or multicellular
- No tissues or organs
How does green algae acquire nutrients and water? - ✔️✔️- Carbon dioxide
- Nitrogen
- Phosphorus
- Water absorbed across cell membrane

What is the ecological importance (historically and presently) of green algae? - ✔️✔️-
Photosynthesis contributes to increased biological production and biodiversity in aquatic
ecosystems
All plant groups contribute to increased biodiversity by providing resources: a)______, b)
_______, and c) _____ - ✔️✔️a) food to consumers
b) oxygen
and c) habitat
Where do non-vascular plants inhabit? - ✔️✔️aquatic and terrestrial ecosystems
What are the characteristics of non-vascular plants? - ✔️✔️- Cells organized into
tissues/organs
- Cuticle and stomata
- No vascular tissue
- Embryo released from plant in a desiccation-resistant spore
What is a waxy layer that prevents water loss from stems and leaves? - ✔️✔️Cuticle
What has pores that allow gas to exchange in photosynthetic tissues and guard cells close
under conditions of water stress (to reduce further water loss)? - ✔️✔️Stomata
How do the cuticle and stomata acquire nutrients and water? - ✔️✔️- Rhizoids anchor plant to
substrate (e.g., soil, wood, rock) and absorb water, nutrients (N,P)
- Carbon dioxide absorbed through stomata
What is the ecological importance (historically) of the cuticle and stomata? - ✔️✔️- Resources
provided by first terrestrial plants enabled evolution of terrestrial consumers
- Explosion in biodiversity, organism abundance, and biological production
Where do seedless vascular plants inhabit? - ✔️✔️aquatic and wet terrestrial ecosystems
What are the characteristics of seedless vascular plants? - ✔️✔️- Cuticle and stomata
- Vascular tissue conducts water, nutrients, and carbohydrates through plants
- Embryo released from plant in a desiccation-resistant spore
How do seedless vascular plants acquire nutrients and water? - ✔️✔️Vascular tissue
- Xylem
- Phloem

__________ conducts water and nutrients from roots to photosynthetic cells - ✔️✔️Xylem
__________ conducts carbohydrates from photosynthetic cells to roots - ✔️✔️Phloem
What is the ecological importance (historically and presently) of seedless vascular plants? -
✔️✔️- Vascular tissue and lignin enable plants to grow tall and inhabit drier habitats
- Increased terrestrial plant abundance and diversity (habitat and food resources) enables
increased biodiversity and organism abundance
Where do gymnosperms inhabit? - ✔️✔️Terrestrial ecosystem
What are the characteristics of gymnosperms? - ✔️✔️- Cuticle and stomata*
- Vascular tissue and lignin*
- Embryo released from plant in a seed*
‣ *Adaptation for terrestrial life
How do gymnosperms acquire nutrients and water? - ✔️✔️Vascular system
What is the ecological importance (historically and presently) of gymnosperms? - ✔️✔️- First
plants capable of reproducing in dry terrestrial habitat
- Increased food and habitat resources and increased biodiversity and organism abundance
Where do angiosperms inhabit? - ✔️✔️aquatic and terrestrial ecosystem
What are the characteristics of angiosperms? - ✔️✔️- Cuticle and stomata*
- Vascular tissue and lignin*
- Embryo released from plant in a seed (surrounded by fruit)*
How do angiosperms acquire nutrients and water? - ✔️✔️Vascular system
What is the ecological importance (historically and presently) of angiosperms? - ✔️✔️-
Emergence of plants with fruit and flowers (with nectar and pollen) provided more food
resources to primary consumers
- Enabling increased biodiversity and organism abundance
What life cycle is this?
1. The mature plant is a haploid (n) gametophyte (i.e., the long-lived life stage that dominated
the life cycle)
