Chapter 29: Plants and the Conquest of Land Supplemental Instruction Iowa State University Leader: Course: Instructor: Date: Kristin Biology 211 Dr. Colbert 9-25-12 1. The green algae called _______ are the closest relative of land plants. a. Cyanbacteria b. Liverworts c. Charophyceans d. Hornworts Key Traits shared with land plants: 1. 2. 3. 2. Distinctive feature of land plants include which of the following? a. Apical Meristems b. No alternation of generations c. Paternally dependent embryos d. Reproductive cells called sponges 3. Alteration of Generations All plants go through a sporic life cycle that is also called an “alternation of generations” life cycle In alternation of generations the plant cycles through a “multicellular _______ gametophyte stage that produces _______, and a multicellular _______ sporophyte stage that produces _______” The _________ produced in alternation are eggs produced in female structures called archegonia, while _______ are produced in male structures called antheridia Spores produced in alternation of generation are haploid cells that “germinate” and produce the multicellular haploid __________ stage by the process of mitosis In alternation of generations the haploid sperm cell and the haploid egg cell _____________ to produce the diploid zygote that develops into the multicellular diploid sporophyte stage through the process of mitosis Haploid spores are produced in the __________ by the process of meiosis 4. Which are all earth’s simplest land plants informally know as bryophytes. (circle all that apply) a. Liverworts (1st 3) b. Mosses c. Hornworts d. Antheridia Key Traits: 1. 2. 3. 4.
