_______:
important structural materials in the support tissues of vascular plants and some algae
lignin:
important structural materials in the support tissues of vascular plants and some algae
The ______, mosses, liverworts, _______, and ______ vascular plants produce spores, but only seed-bearing plants produce pollen.
The fungi, mosses, liverworts, hornworts, and seedless vascular plants produce spores, but only seed-bearing plants produce pollen.
pterophytes蕨类植物: ferns and horsetails species: 13000 different species maximum height: 20m with lignin? yes vascular tissue present? yes fertilization require water? yes seeds present? no, spore does seeds develop inside ovary？ no does double fertilization and triple fusion occur? no flowers present? no
pterophytes蕨类植物: ferns and horsetails species: 13000 different species maximum height: 20m with lignin? yes vascular tissue present? yes fertilization require water? yes seeds present? no, spore does seeds develop inside ovary？ no does double fertilization and triple fusion occur? no flowers present? no
gymnosperm: conifers松果, cycads苏铁, ginkgo银杏 species: 1000 height: 115.8m lignin: yes vascular tissue: yes does fertilization need water? no seed present? yes do seeds develop inside ovary? no,develop on surface of leaves does double fertilization and triple fusion occur? no flower present? no

Describe adaptations that plants acquired which led to their increasing complexity:
______ and _____ tetrads:
resistance to dry
travel far away
_______, _______, -____ and _____:
to stand up tall to have more light
to transport nutrients
____:
dispersal to a new location, and dormancy during unfavorable conditions
_____:
double fertilization and triple fussion:
produce endosperm (It surrounds the embryo and provides nutrition in the form of starch)
______:
The primary purpose of a flower is reproduction.

Lignin, vascular tissue, stomata and roots:
to stand up tall to have more light
to transport nutrients
seeds:
dispersal to a new location, and dormancy during unfavorable conditions
ovary:
double fertilization and triple fussion:
produce endosperm (It surrounds the embryo and provides nutrition in the form of starch)
flowers:
The primary purpose of a flower is reproduction.
Bryophyte (evolve \_\_\_\_\_\_, \_\_\_\_\_) Pterophyte (\_\_\_\_\_, \_\_\_\_\_\_\_) Gymnosperm (\_\_\_\_\_\_, \_\_\_\_\_, \_\_\_\_\_) Angiosperm
Bryophyte
(evolve vascular tissue, lignin)
Pterophyte
(seed, fertilization doesn’t require water)
Gymnosperm
(double fertilization, flower, seed in ovary)
Angiosperm
bryophyte 3m 20000 mosses, liverwort no lignin no vascular tissue no seed
bryophyte 3m 20000 mosses, liverwort no lignin no vascular tissue no seed
