BIOL 198 Module 6 Objectives with Certified Solutions Examine the symbiotic interaction of algae and fungi Lichen is a relationship between fungi & autotrophs Algae make food & fungi gives it a home Role of lichens They break down soil for the next organism Characteristics of algae Eukaryote Has cell wall, single & multi cellular, nucleus, mitochondria, autotrophic, aquatic Role of algae Primary producer, makes CO2, carbs Food source for fish Understand the evidence supporting the hypothesis that land plants and aquatic green algae evolve from a common ancestor Both eukaryotic, autotrophic, cell walls, same photosynthetic pathways, DNA evidence Describe the environmental challenges against living on land and adaptations plants have Dessication- waxy covering to protect from losing H2O structural support(gravity)- reinforced cell walls radiation- making sure life cycle is to avoid haploid reproduction- gametes that swim & ones that don't transport of H2O- apical & lateral meristems Describe the four main categories of plants that are displayed in the studio and provide and example of each Bryophtyes- small, mosses Seedless vascular- vascular system, homosporous, ferns, seedless plants Gymnosperms- vascular system, have seeds, heterosporous, trees Angiosperms- have seeds, heterosporous, flowers, fruits Understand the main differences in the life cycles of bryophytes, seedless vascular, gymnosperms, angiosperms Have seeds or not, reproduction: asexual or sexual, homosporous or heterosporous Learn the difference between the sporophyte and gameophyte generations of plants Sporophyte: haploid, meiosis, zygote Gameophyte: diploid, mitosis, gamete Summarize the evolutionary trends among plants Land---water---vascular tissue Define vegetative(asexual) reproduction mitosis, Only one plant is involved and the offspring is the result of one parent Advantage: faster reproduction rate= eye of potato Disadvantage: genetic diversity is very low, identical Learn parts of plant Peticole- between leaf and stem Internode- space on stem between 2 leaves Shoot system- stem Root system- roots Learns parts of flower Petal
