1 Biology, 7e (Campbell) Chapter 29: Plant Diversity I: How Plants Colonized Land Chapter Questions 1) One of the major distinctions between plants and the green algae is that A) only green algae have flagellated, swimming sperm. B) embryos are not retained within parental tissues in green algae. C) meiosis proceeds at a faster pace in green algae than in plants. D) chlorophyll pigments in green algae are different from those in green plants. E) only plants form a cell plate during cytokinesis. Answer: B Topic: Concept 29.1 Skill: Comprehension 2) The most recent common ancestor of all land plants was most similar to modern-day members of which group? A) Cyanobacteria B) red algae C) Charophycea D) brown algae E) golden algae Answer: C Topic: Concept 29.1 Skill: Knowledge 3) Peptidoglycan is to the structural integrity of bacteria as ________ is to the structural integrity of plant spores. A) lignin B) cellulose C) terpene D) tannin E) sporopollenin Answer: E Topic: Concept 29.1 Skill: Comprehension 4) Which kind of plant tissue should lack phragmoplasts? A) bryophyte tissues of the gametophyte generation B) diploid tissues of charophyceans C) spore-producing tissues of all land plants D) tissues performing nuclear division without intervening cytokineses E) the meristematic tissues of fern gametophytes Answer: D Topic: Concept 29.1 Skill: Comprehension

5) The following are common to both charophyceans and land plants except A) sporopollenin. B) lignin. C) chlorophyll a. D) cellulose. E) chlorophyll b. Answer: B Topic: Concept 29.1 Skill: Comprehension 6) A number of characteristics are very similar between charophyceans and members of the kingdom Plantae. Of the following, which characteristic does not provide evidence for a close evolutionary relationship between these two groups? A) alternation of generations B) chloroplast structure C) cell plate formation during cytokinesis D) sperm cell structure E) ribosomal RNA nucleotide sequences Answer: A Topic: Concept 29.1 Skill: Comprehension 7) A researcher wants to develop an assay (test) that will distinguish charophyceans and land plants from chlorophyte green algae. Which of the following chemicals would be the best subject for such an assay? A) chlorophyll b -- an accessory photosynthetic pigment B) carotenoids -- a class of accessory photosynthetic pigments C) amylopectin -- a starch-like food storage material D) glycolate oxidase -- an enzyme of peroxisomes that is associated with photorespiration E) flavonoids -- a class of phenolic compounds that is often associated with chemical signaling Answer: D Topic: Concept 29.1 Skill: Application 8) In animal cells and in the meristem cells of land plants, the nuclear envelope disintegrates during mitosis. This disintegration does not occur in the cells of most protists and fungi. According to our current knowledge of plant evolution, which group of organisms should feature a mitosis most similar to that of land plants? A) unicellular chlorophytes
