Lab Practical 4: Survey of the Plant
Kingdom terms with definitive solutions.
plants - Answer -evolved from freshwater green algal species
more than 550 million years ago
-autotrophic, contain chlorophyll a, have cell walls containing
cellulose
-alternation of generations
plant life cycle - Answer -haploid gametophytes alternate with
diploid sporophytes
-gametophytes produce antheridia and archegonia from mitosis
-sperm and eggs fuse during fertilization to produce first diploid
cell of sporophyte (zygote)
-meiosis occurs within sporangia (the spore producing organs of
sporophyte)
, -resulting spores are haploid and first cells of gametophyte
generation
Phylum Hepaticophyta - Answer liverworts
Phylum Bryophyta - Answer mosses
Phylum Anthocerotophyta - Answer hornworts
Phylum Pterophyta - Answer ferns
Phylum Lycophyta - Answer club mosses
Phylum Cycadophyta - Answer cycads
Phylum Ginkgophyta - Answer Ginkgo
Phylum Coniferophyta - Answer conifers
Phylum Gnetophyta - Answer gnetophytes
Phylum Anthophyta - Answer flowering plants
Why is Sphagnum often used in shipping items that must be kept
moist? - Answer It absorbs any extra water that is around
asexual reproduction in mosses - Answer fragmentation
