QUIZ/ANSWER FOR BIO 211 LAB
PRACTICUM 2024/25 VERIFIED A+
ASSUARANCE
Land plants (CORRECT ANSWER)Vascular (seedless and seed plants)
and nonvascular/bryophytes


Nonvascular plants include (CORRECT ANSWER)Hepatophyte
(liverworts), Bryophyta (mosses), Anthocerophyta (hornworts)


Seedless vascular plants phylas (CORRECT ANSWER)lycophytes
(club mosses) and monilophytes (ferns)


Vascular seed plants phylas (CORRECT ANSWER)Gymnosperms
(Ginkophyta, Gnetophyta, Cycadophyta, Coniferophyta) and
angiosperms (monocot and dicot)


Derived traits of land plants (not present in ancestral algae):
(CORRECT ANSWER)▻ Alternation of generations
(with multicellular dependent embryo)
▻ Walled spores produced in sporangia
▻ Multicellular gametangia
▻ Apical meristem

,Other derived traits related to terrestrial life: (CORRECT ANSWER)▻
Cuticle
▻ Stomata


Bryophytes (non-vascular plants) (CORRECT ANSWER)-Gametophyte
dominant
-sporophyte reduced, dependent on gametophyte for nutrition
-no roots or stems
-transfer nutrients through diffusion
-water transfer through osmosis
-limited growth potential
-need water for reproduction


Seedless vascular plants (CORRECT ANSWER)-Sporophyte dominant
-gametophyte= reduced, independent (photosynthetic and free-living)


Seed plants (gymnosperms and angiosperms) (CORRECT ANSWER)-
Sporophyte dominant
-Gametophyte= reduced, dependent on surrounding sporophyte tissue
for nutrition
-have roots and stems ; connective tissue


Gametophyte (CORRECT ANSWER)Haploid (n) stage of life cycle

,Sporophyte (CORRECT ANSWER)diploid (2n) stage of life cycle


Gametangia (CORRECT ANSWER)Multicellular sex organs


Female= archgonia
Male= Antheridia


Bryophote Sporophyte (CORRECT ANSWER)-Sporophyte grow out of
archegonia


-Sporophyte consists of a foot a seta (stalk) and a sporangium


-Hornwort and moss sporophyte have stomata for gas exchange


Alternation of generations (CORRECT ANSWER)► Plants alternate
between two multicellular stages, a reproductive cycle called alternation
of generations
► The gametophyte (n) is haploid and produces haploid gametes by
mitosis
► Fusion of the gametes gives rise to the diploidsporophyte (2n), which
produces haploid (n) sporesby meiosis


How do mosses anchor themselves in the soil? Are they true roots?
(CORRECT ANSWER)Anchor themselves with rhizoids- not true roots

, Bryophytes gametophyte (CORRECT ANSWER)In all three bryophyte
phyla, gametophytes are larger and longer-living than sporophytes


-sporophytes present only part of time


All nonvascular plants rely on... (CORRECT ANSWER)water for
reproduction


Morphology of liverworts


Liverworts = Hepatophyta = Nonvascular (bryophytes) (CORRECT
ANSWER)Liverwort gametophyte has Gemmae cups


Purpose of gemmae cups: to detach from plant and reproduce -
reproduce asexually


five derived traits of seed plants (CORRECT ANSWER)reduced
gametophytes, heterospory, ovules, pollen, seeds


Phylum Monilophyta (Ferns)


Monilophyta = seedless vascular plants= vascular plants (CORRECT
ANSWER)-photosynthesis occurs in stems
-under fern leaves = sporangia (carries spores); depends on h20 or wind
