Single-celled eukaryotes are
Protists
Archaea
Land plants
Animals
Which features set most of the members of protista apart from the rest of the kingdoms?
Unicellular and microscopic
Multicellular and microscopic
Photosynthetic and unicellular
None of the answer choices is correct.
The (a) algae are thought to be closely related to the first plants because they share most of the characteristics of plants.
Members of which genus of algae are found in ponds and have chloroplasts that are arranged in a spiral?
Spirogyra
Euglena
Chlamydomonas
Volvox
An organism that will feed on dead plants, animals, and microbes are called
autotrophic
heterotrophic
saprotrophs
parasitic
(a) are organisms that break down dead organic matter in order to absorb the nutrient molecules.
(a) are mostly saprotrophic decomposers that assist in recycling of nutrients in ecosystems.
They are both heterotrophic and play an important role in ecosystems. They both have cell walls of the same material. They are both photosynthetic and thus are producers. They are both eukaryotic. Which statement is correct?
They are both heterotrophic and play an important role in ecosystems.
They both have cell walls of the same material.
They are both photosynthetic and thus are producers.
They are both eukaryotic.
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 attack and engulf food for internal digestion.
Fungi have flagella at some stage, providing mobility that plants never have.
Plants are multicellular and fungi are unicellular or multinucleated noncellular plasmodia.
Plants store glycogen, while fungi store starch.
Fungi are NOT photosynthetic because they lack
xylem.
cell walls.
chloroplasts.
cell membrane.
A chain of asexual spores produced by a sac fungus is called
a mycelium.
a conidia.
an ascospore.
a basidiospore.
When the cap of an average gilled mushroom is cut off and shaken, a cloud of powdery material is released. The material released are
mycelia
sporangia
hyphae
spores
seeds
