Which of the following pairs of protists and their ecological roles are correctly matched? A) 8) Apicomplexans-parasites of animals C) es of plants soll organisms A) Possess two flagella B) Are all autotrophic C) Lack mitochondria D) Include species that cause malaria Which of the following approaches would be most likely to cause evolution of a drug- resistant strain of Plasmodium? A) B) C) D) According to the phylogeny presented in this chapter, which protists are in the same eukaryotic supergroup as plants? A) Green algae B) C) Red algae D) The most direct ancestors of land plants were probably A) 8) C) D) The structural integrity of bacteria is to peptidoglycan as the structural integrity of plant 36. Widespread, frequent spraying to kill mosquitoes Use of a cocktail of three drugs in patients suffering from malaria Widespread, frequent use of a single drug in patients suffering from malaria Widespread use of anti-mosquito bed nets 37. Dinoflagellates Both A and C Kelp (brown alga) that formed large beds near the shorelines 38. Green algae Liverworts and mosses 39. spores is to A) Lignin B) Cellulose C) Secondary compounds D) Sporopollenin 40. According to our current knowledge of plant evolution, which group of organisms should feature cell division most similar to that of land plants? A) Some unicellular green algae B) Some cyanobacteria C) Some charophytes D) Some red algae Three of the following are evidence that charophytes are the closest algal relatives of plants. Select the exception. A) Similar sperm structure B) 1. C) D) The presence of chloroplasts Similarities in cell wall formation during cell division Genetic similarities in chloroplasts
Carophytes are most closest relative
of plants.Charophytes are similar to modern plants. Both have
cellulosic cell walls, cell plates during cytokinesis, carbon
storage in the form of starch, possession of chlorophyll b as an
accessory pigment, and similar RNA and DNA sequences for particular
Euglenoids can make their food in
presence of sunlight because they possess chlorophyll and the are
also heterotrophic in absence of sunlight.
Dinoflagellate possess two
flagella-one transverse and one longitudinal that produce whirling
whip movement in dinoflagellates.
Uses of antimalarial drug makes
plasmodium drug resistant.
