You are watching: Why aren’t the three rrna genes of corn one another’s closest relatives?
Why aren"t the 3 rRNA genes of corn one another"s closest relatives?1. Since corn is a hybrid of yeastern, cyanobacteria, and E. coli 2. Endosymbiosis in the ancestor of corn gave it the capacity to photosynthesize and respire3. Endosymbiosis in the ancestors of eukaryotes, and also again in photofabricated eukaryotes brought about the advancement of mitochondria and also chloroplasts, which retain parts of their original genomes.
If you sequenced the chloroplast of wwarm, wright here would certainly you mean it to show up on the phylogenetic tree?1. The wwarmth sequence would show up closest to the ancestor of the cyanobacterium Chlorobium and also sequence of the corn chloroplast.2. The wheat sequence would show up closest to the corn chloroplast just. 3. The wheat sequence would certainly show up in between the three corn ribosomal sequences
Which of the following is a synapomorphy of stoneworts and also land plants? 1. Chloroplasts 2. Chlorophyll b 3. Multicellular sporophyte 4. Retention of the egg in the parental organism 5. Branched apical growth
a. Evolution of a water-impermeable cuticlec. Evolution of gametangiad. Evolution of a mechanism for structural supporte. A mutualistic association with a fungus that promotes nutrient uptake
Identify the adaptations evolved in the widespread ancestor of land plants that permitted the successful emigration of land also.Select all that use.a. Evolution of a water-impermeable cuticleb. Evolution of a carbohydprice energy-storage molecule c. Evolution of gametangiad. Evolution of a device for structural supporte. A mutualistic association through a fungus that promotes nutrient uptake
Within vascular plants, the large, significant plant is the ----- , in nonvascular plants it is the -----.
Which team has gametophytes that are green, leafprefer layers that lie level on the ground? 1. Liverworts 2. Hornworts 3. Mosses 4. Stoneworts 5. Horsetails
Genetic recombicountry deserve to occur in many various steras. Identify the feasible stperiods below.Select all that apply. 1. Horsetail sporangia 2. Moss sporophyte 3. Fern sori4. Club moss strobili 5. Moss gametophyte
Why are mosses dependent on water for reproduction?1. Because sperm are passively transported to eggs by water. 2. Because gametogenesis occurs only as soon as the plants are moist. 3. Since eggs and also sperm are released right into water and then unite. 4. Because sperm have to swim through water to reach and fertilize eggs.
Which group frequently has big leaves through branching vascular strands, have the right to reach heights of as much as 20 meters, and has actually sporangia generally clustered in groups called sori? 1. Ginkgoes 2. Horsetails 3. Ferns 4. Hornworts
Which type of land plant possesses the microphyll leaf? 1. Horsetails 2. Club mosses 3. Mosses 4. Ferns 5. Liverworts
How is the megaphyll found in ferns and also seed plants thought to have evolved? 1. from sterile sporangia. 2. by the process of meiosis. 3. by the procedure of heterospory. 4. as an outcome of overtopping.
Throughout the evolution of the land plants, the sporophyte generation has actually end up being ---- and even more independent of the gametophyte.The gametophyte generation has come to be ----- and even more dependent on the sporophyte.
A difference in between gymnosperms and also angiosperms is that gymnosperms ... 1. execute not create seeds. 2. do not develop flowers. 3. execute not have actually tracheid cells. 4. count specifically on wind for fertilization. 5. have additional growth.

The two significant clades of angiosperms, the monocots and also eudicots, differ in the number of 1. sperm involved in fertilization. 2. sexes per plant; monocots have one sex per plant, and eudicots have actually both sexes in one plant. 3. sexes per plant; eudicots have male and female plants, and also monocots have both sexes in one plant. 4. embryonic cotyledons. 5. tracheid types.
Which is true of the eudicots? 1. has the magnoliids. 2. has many kind of herbs, vines, shrubs, and also trees. 3.along with the monocots, eudicots are the just extant angiosperm clades. 4. they are not a clade. 5. include orchids and also palm trees
