LO 1) Classify an unknown organism as a plant or green algae, based on its characteristics.
- Basal characteristics of plants: spores walled with sporopollenin, usually, cuticles, stomata,
vascular tissue, & roots. Multicellular dependent embryo, apical meristem (gros towards light) &
alternation of generations.
Identify the challenges of the terrestrial environment for organisms, and the adaptations plants
evolved that overcame these challenges.
The problems:
- Desiccation: spores walled with sporopollenin, cuticle, stomata, vascular tissue, & roots.
- Fertilization out of water: multicellular, dependent embryo, pollen grains, & seeds.
- Gravity: apical meristem (grows towards light), true roots, & vascular tissue.
Identify benefits of the terrestrial environment compared to the aquatic environment that help
explain why life colonized land.
Benefits: Land has more CO2, sunlight, and untapped nutrients.
Recreate and label the generalized plant life cycle
Identify the dominant life stage of a plant (i.e., sporophyte or gametophyte) from a description.
Sporophyte = what a zygote turns into

Gametophyte = what spores turn into,
Using the general plant life cycle, explain how and when plants disperse.
Classify an unknown plant into one of the four major plant groups, based on its characteristics:
bryophytes, seedless vascular, gymnosperms, and angiosperms
Bryophytes: use water for fertilization (no roots)
Seedless vascular: use water for fertilization, has roots
Gymnosperms: seeds (no fruit)
Angiosperms: only group w/ fruits and flowers
Distinguish stages and components of the bryophyte or seedless vascular plant life cycles from
other plant life cycles and each other.

Identify bryophyte or seedless vascular plant groups by their common names.
seedless vascular plant ferns
bryophyte = moss
Identify ecosystem services provided by bryophytes or seedless vascular plants.
LO 2) Compare asexual and sexual reproduction in plants, and distinguish between them when
described
Asexual is better for stable environments
Distinguish stages and components of the gymnosperm and angiosperm life cycles from other
plant group life cycles, and from each other
- 5 derived traits for seed plants (tiny gametophytes, heterospory (micro,megaspore), ovules,
pollen, & seeds
- Angiosperms = only group that flowers & makes fruit
Identify the four major gymnosperm groups and the four major angiosperm groups by name or
