Chapter 29 Flashcards
Single-celled eukaryotes are
Protists
Which features set most of the members of protista apart from the rest of the kingdoms?
unicellular and microscopic
The ____ algae are thought to be closely related to the first plants because they share most of the characteristics of plants.
green
Members of which genus of algae are found in ponds and have chloroplasts that are arranged in a spiral?
Spirogyra
What is an example of an alga?
diatoms
Paramecium
cilia
ciliates
cilia
amoeboids
pseudopodia
Which of the following organisms move about by means of pseudopodia?
A. trypanosome
B. Amoeba proteus
C. Chlamydomonas
D. Paramecium caudatum
B. Amoeba proteus
The kingdom ____ are characterized by having filaments called hyphae that are used to absorb nutrients.
Fungi
Molds (except slime and water molds) and mushrooms belong to the kingdom
Fungi
An organism that will feed on dead plants, animals, and microbes are called
saprotrophs
____ are organisms that break down dead organic matter in order to absorb the nutrient molecules.
saprotrophs
____ are mostly saprotrophic decomposers that assist in recycling of nutrients in ecosystems.
Fungi
In what way are fungi like heterotrophic bacteria?
They are both heterotrophic and play an important role in ecosystems.
At one time, biologists thought that fungi were merely forms of plants that had lost their chlorophyll and had returned to saprotrophy to gain food. Why is this no longer considered a solid theory?
Fungal cell walls contain chitin rather than cellulose.
Fungi are NOT photosynthetic because they lack
chloroplasts
A chain of asexual spores produced by a sac fungus is called
a conidia.
The mycelium is a mesh of filaments, each of which is called
a hypha.
When the cap of an average gilled mushroom is cut off and shaken, a cloud of powdery material is released. The material released are
spores.
Amoebae have…
have pseudopodia, have a nucleus, are heterotrophic.
Diatoms
are unicellular algae with glassy cell walls
Euglena
is an excavate, has an eyespot.
