, 13. Seeds contain a(n) __________ and nutritive tissue: embryo
14. Which of the following terms include all others: ==VASCULAR PLANT== fern
seed plant angiosperm gymnosperm
15. Heterospory is an example of a __________ trait. All the plants that are
heterosporous form a __________ group: Homoplastic
Polyphyletic
16. Diplospirilla: G on photo
17. Staphylococci:
18. Staphylobacillus:
19. Streptobacillus:
20. True or false? Gram Negative cells appear dark purple after Gram staining due
to high amount of peptiodoglycan on the exterior surface of their cell walls:
False
21. Which of the following characteristics are used to distinguish bacteria and
archaea as prokaryotes (and not eukaryotes): Circular chromosome
Lack of nuclear membrane
22. A scientist engineers a virus that contains the gene thought to provide bacterial
resistance to the antibiotic vancomycin. The scientist then takes a culture of
bacteria and divides it in two. One portion is allowed to incubate with the
previously mentioned virus, while the other is not. Both bacterial cultures are
then placed onto petri plates whose media contain vancomycin. Only the culture
grown previously with viruses shows growth of bacterial colonies.
