BIO 152 MODULE COMPREHENSIVE
PRACTICE SOLUTION 2026 TEST BANK
GRADED A+
⩥ Con of Land Transition. Answer: Cells Dry Out
⩥ Con of Land Transition. Answer: Have less physical support
⩥ Con of Land Transition. Answer: Sperm will have a harder time
fertilizing eggs
⩥ Traits of Charophytes that suggests they're closely related to land
plants. Answer: Cellulose cell wall, Chlorophyll a&b, two anterior
flagella
⩥ Pre-adaptations of Charophytes. Answer: Fresh Water, Life cycle that
allows dispersal by wind - using spores, spores covered in sporopollenin,
can associate with mycorrhizal fungi
⩥ Plant Adaptations. Answer: Cuticle - conserve water
⩥ Cuticle. Answer: inhibits gas exchange, so stomata and pores are
needed
,⩥ Plant Adaptation. Answer: Embryo - hence embryophytes
⩥ How many spores does a charophyte doing zygotic meiosis make for
each fertilization event?. Answer: 4
⩥ Plant Adaptation. Answer: Alternation of Generations
⩥ Gametophyte. Answer: (haploid) makes gametes by mitosis
⩥ Sporophyte. Answer: (diploid) makes spores by meiosis
⩥ Spore. Answer: Makes gametophyte by mitosis
⩥ embryo. Answer: young sporophyte that is nourished by maternal
tissue, made from zygote by mitosis
⩥ When does meiosis occur in the land plant life cycle?. Answer: During
the formation of spores by the sporophyte
⩥ Bryophytes. Answer: Liverworts, Mosses, Hornworts - All are very
short, live in moist understories of forests, gametophyte dominant,
sporophyte dependant
, ⩥ Liverworts. Answer: Have pores instead of stomata
⩥ Mosses. Answer: Have stomata (all lineages after too), economically
important - florist trade and peat
⩥ Hornworts. Answer: Sporophyte long lived (longer than other
bryophytes)
⩥ Why do all derived lineages have vascular tissues?. Answer: Over-
time sporophytes became larger, more complex, and acquired a vascular
system
⩥ Why did plants get taller?. Answer: Being taller than competitors is
important
⩥ Con of height. Answer: water needs to be transported to their leaves,
sugars made in the leaves need to be transported to all other cells (roots
and stems)
⩥ Did vascular tissue or branched sporophyte evolve first?. Answer:
Branched sporophyte first, Cooksonia - was a branched, non-vascular
plant(extinct)
