II. Identification: Identify and write on the spaces provided the structures being described by
the following statements.
Cell membrane
___________________
1. It controls diffusion in and out of the bacterial cell.
Mycelium
___________________
2. It is the mass of interconnected hyphae.
Plasmids
___________________
3. It is the unique structure among prokaryotic cells, which is a circle of DNA that
is believed to be an excised portion of the chromosome.
Ribosome
___________________
4.These are sites of protein assembly, which may occupy 25% of the volume of a
typical bacterial cell.
Sex pili
___________________
5. It is the type of pili that facilitate the transfer of DNA during conjugation.
Nucleoid
___________________
6. It is the DNA-containing area of prokaryotic cells such as bacteria.
Capsule
___________________
7. It keeps the bacterium from drying out and to protect it from phagocytosis
(engulfing) by larger microorganisms.
Capsule
___________________
8. It keeps the bacterium from drying out and to protect it from phagocytosis
(engulfing) by larger microorganisms.
Somatic pili
___________________9.
It is the type of pili that allows the bacteria to adhere to various surfaces.
Flagella
___________________10.
It provides a means of locomotion for those bacteria that have them.
Cell wall
___________________11.
In bacteria, this structure is made of peptidoglycan.
Septa
___________________12.
It is the incomplete barrier that divides the hyphae of fungi.
Proglottids
___________________13.
These are the segments in tapeworms that contain reproductive organ.
Scolex
___________________14.
It is the segment of tapeworms that attaches to the intestinal wall of the hosts.
Pseudocoelom
___________________15.
This structure of a nematode separates the endoderm-lined gut from the rest
of the body.
III. True or False. Study the following statements. Write T if the statement is true, and F if false in the space
provide.
______1. Bacteria are the only organisms with prokaryotic cellular organization.
______2. Bacteria, along with fungi, are the only organisms capable of fixing atmospheric
nitrogen.
______3. Yeasts are unicellular, primitive fungi.
______4. Fungi are saprophytes.
______5. Flatworms with digestive cavity have an incomplete gut, one with only one opening.
______6. Tapeworms are divided into three zones: scolex, segmented neck and proglottids.
______7. Each proglottid is a complete hermaphroditic unit, containing both male and female
reproductive organs.
______8. Nematodes are bilaterally symmetrical, segmented worms.
______9. Flagella among bacteria allows the transfer of genomic materials during comjugation.
______10. Fungal cell wall are made of hard structures called peptidoglycan.
