Which of the following statement(s) is/are TRUE?
a. yeasts are unicellular fungi
b. molds and mushrooms are filamentous fungi. The filaments are chains of cells called "hyphae"
C. most protozoa are unicellular, animal-like members of Domain Archaea, many of which are motile
and lack cell walls
d. algae have historically been described as "plant-like" protists because they contain chloroplasts
and cell walls
e. organisms which make chlorophyll a can perform oxygenic photosynthesis
f. all organisms which make chlorophyll a have chloroplasts
g. Nostoc, algae and plants all make chlorophyll a and all have chloroplasts
h. Nostoc, algae and plants have mitochondria which evolved from primitive endosymbiotic bacteria
i. Photoautotrophs perform photosynthesis and chemoheterotrophs require pre-formed organic
molecules as a source of carbon and energy
j. Cyanobacteria, algae and plants are photoautotrophs. Fungi, protozoa and animals are
chemoheterotrophs
k. Most bacteria, all fungi, all algae…
Which of the following does not explain why slime molds and multicellular algae are included in the Kingdom Protoctista? They
A. lack important characteristics of the plants and fungi.
B. use an amoeboid type of movement.
C. classification system is trying to reflect phylogenetic relationships.
D. appear to be more closely related to unicellular eukaryotes.
