Bio 152-Exam 2:plants UPDATED Exam
Questions and CORRECT Answers
An unknown organism can be identified as a fungus if it...
-Is multicellular and photosynthetic
-Lacks cell walls and reproduces by spores
-Has prokaryotic cells and cell walls made of cellulose
-Has cell walls made of chitin and obtains its food by secreting enzymes to break down food
molecules in the environment
-Is unicellular, eukaryotic, and digests large food molecules intracellularly. - CORRECT
ANSWER - Has cell walls made of chitin and obtains its food by secreting enzymes to
break down food molecules in the environment
Which environment would most likely harbor diverse and prolific fungal populations?
-Rocky terrain, with few plants or animals
-A hot, sunny desert with minimal annual rainfall
-A shady and damp forest floor covered in leaf litter
-A patch of soil exposed to constant fluctuations in moisture level
-A bright and cool prairie with little animal disturbance - CORRECT ANSWER - A shady
and damp forest floor covered in leaf litter

The algal partner in lichen symbiosis is responsible primarily for
, -Respiration
-Food production
-Defense
-Reproduction
-Water storage - CORRECT ANSWER - food production
Plants with active mycorrhizae...
-Display reduced levels of photosynthesis
-Display enhanced absorption of water and minerals (especially phosphorus).
-Are heavily parasitized and die
-Tend to contain less chlorophyll
-Have fewer endophytes living in aboveground tissues - CORRECT ANSWER - Display
enhanced absorption of water and minerals (especially phosphorus).
Which Statement about the role of zygospore in the life cycle of zygospore fungi is true?
-It allows the sport to be dispersed by animals rather than the wind.
-It forms a dormant resting stage for the products of sexual reproduction
-It is the only dispersal stage of these fungi
-It can fuse with another zygospore to produce a zygote
-It is the only flagellated stage of the zygospore life cycle - CORRECT ANSWER - It
forms a dormant resting stage for the products of sexual reproduction
Which process contributes to genetic diversity within a fungus population?
-Fragmentation
-Formation of conidia
-Budding
-Production
Karyogamy - CORRECT ANSWER - karyogamy
