KSU BIOLOGY 1108 FINAL EXAM QUESTIONS
AND ANSWERS LATEST 2025-2026 UPDATE
Seed plant origin - Answer-400-65 MYA
Flowering Plant diversification - Answer-150-100 MYA
Most dominant embryophytes - Answer-Flowering plants
Plasmodesmata - Answer-Holes in cell wall that interconnect different
plant cells
Phragmoplast - Answer-where the cell plate forms during cell division
Byrophytes (what/life stage) - Answer-Liverworts, hornworts,
mosses..... haploid gametophyte is dominant life stage
Lycophytes (what/life stage) - Answer-Spikemosses, Quillworts,
Clubmosses......diploid sporophyte is dominant lifestage
Ferns (what/life stage) - Answer-Closest relative to seed
plants.......sporophyte is dominant life stage
,Evolution of seed plants - Answer-Green alga > Embryophytes >
Vascular plants > Lycophytes > Ferns > seed plants
Conifers - Answer-male and female cones
Cycads - Answer-Separate male and female plants
Ginkgo - Answer-Separate male and female plants.... males used as
ornamental plants
Gnetophytes - Answer-Separate male and female plants
Basal Angiosperm Characteristics - Answer-Leaves are vein like, ring
arranged vascular tissue, one main root, one pollen opening
Monocot characteristics - Answer-one cotyledon, parallel veins,
scattered tissue, no main root, one pollen opening
Eudicot Characteristics - Answer-two cotyledons, netlike veins, ring
ranged vascular tissue, three pollen openings
First branching angiosperm lineage - Answer-Amborella
Bees as pollinators - Answer-Consume a lot of pollen so some pants
will hide it from them
, Butterflies/moths as pollinators - Answer-tubular flowers..... most
flowers are white and produce scent at night
Flies as pollinators - Answer-dead animal like flowers
Bats as pollinators - Answer-study, white flowers, fragrant at night
Hummingbirds as pollinators - Answer-red flowers, tubular, no
fragrance
wind as pollinators - Answer-flowers that create a lot of allergies, green
flowers that lack petals
Pseudocopulatory - Answer-Orchids trick bees into mating with them to
induce pollination
Plant primary growth - Answer-shoot and meristem (area of rapid cell
division)
Plant secondary growth - Answer-growth in the stem.... create of xylem
(dead) and phloem (living)
Importance of transpiration - Answer-Pulls nutrients up towards top of
plant and allows CO2 to enter
