9. Plant Jike photownthesis that releases oxygen occurs in cyanobacteria Gram positive bacteria Archaea d. Spirochaetes 10. According to e the endosymbiotic theory of the origin of eukaryotic cels, how did mitochondra a protoeukaryote engaged in a symbiotic relationship with a protocel a. when membrane folded in and there were mutations of genes for proteins in enerey- by secondary endosymbiosis 11. T/F: Refer to tree below: Oomain Archaea is more closely related to Domain Bacteria than Domain Eukarya Mato 12. What shape are these bacteria? Coccus b. Bacillus c. Spirillum Page 1 2Explanation / Answer
9. a) Cyanobacteria are a phylum of bacteria which can produce their energy through photosynthesis and can release oxygen in the process.
10. d) From engulfed, originally free living proteobacteria. Secondary symbiosis is engulfing one eukaryotic organism that has already undergone primary symbiosis, by other eukaryotic organism, but mitochondria originated by an endosymbiotic event when a bacterium was captured by a eukaryotic cell.
11. False. Because domain Archaea is more closely related to domain Eukarya as their most recent common ancestor are much closer.
12. Coccus is a spherical or near spherial or round shape of a bacterium. In plural, it is mentioned as cocci.
13. d) Unikonta superfamily includes both animals and fungi. This supergroup is divided into two major groups: the Amoebazoans and the Opisthokonts. The amoebozoans contain only protists while the opisthokonts include the fungi and animal kingdoms and some closely related protists also.
14. True by all meanns, as the evolution of a species depends on changes in the genome of a species and phylogeny can track those changes and draw relations between evolved species.
15. False. Orthologs are genes in different species those evolved from a common ancestral gene by speciation.
16. B. Meiosis in sporophytes produce haploid spore. Alternation of generation is depicted by presence of both diploid and haploid stages.
17. C. Gametophytes. Spores go through mitosis in order to develop into gametophytes.
18. B. Vascular tissues are not found in all land plants.Bryophyta (mosses), Marchantiophyta (liverworts), and Anthocerotophyta (hornworts) are all non vascular land plants.
19. Charophytes are a type of green algae whic are relative of land plants.
20. Sporopollenin is present in walls of spores and pollens.
21. Vascular tissue isassociated with cell wall formation. Vascular cambium and cork cambium are vascular tissues asssociated in formation of secondary cell walls.
