Prokaryotes & Microorganisms
All cells have these three features: ribosomes, plasma membrane, and _____.
DNA
Protists are classified as this type of cell.
Eukaryotic cells
The threadlike structures that make up many fungi are called ____
Hyphae
This type of symmetry is generally associated with a sessile lifestyle.
Radial Symmetry
This phylum includes sponges.
Porifera
This is the process by which phages transfer genes between bacteria.
Transduction
Protists with perforated, glass-like walls are called these.
Diatoms
Fungi can function as decomposers or as these organisms living in association with other organisms.
Symbionts
An animal with strong cephalization would be expected to have concentration of sensory structures at this end.
Anterior end
Corals belong to this phylum.
These organisms use CO₂ for carbon and inorganic substances such as H₂S for energy.
Chemoautotrophs
Protists that can switch between autotrophic and heterotrophic nutrition are called these.
Mixotrophs
During fungal sexual reproduction, karyogamy is the fusion of these.
Haploid nuclei
An animal that is neither diploblastic nor triploblastic and lacks nerve and muscle tissue is most likely this phylum.
Porifera
Roundworms belong to this phylum.
Nematoda
Euryarchaeota that produce CH₄ by using CO₂ and H₂ are called these.
methanogens
Chagas disease, African sleeping sickness, and leishmaniasis are associated with this group.
kinetoplastids
The fungal group known as the “sac fungi” is called _____.
Ascomycota
Spiral cleavage is characteristic of this major developmental group.
Protostomes
This phylum has segmentation, a well-developed coelom, a ventral nerve cord, and a closed circulatory system
Annelida
Antibiotics can target bacterial protein synthesis without necessarily harming human cells because bacterial and eukaryotic _____ differ.
ribosomes
A student says protists lack a nucleus because they are like bacteria. Explain why this statement is incorrect.
Protists are eukaryotes, so they have a nucleus and other membrane-bound organelles.
Plants involved in mycorrhizae and photosynthetic cells in lichens provide this to their fungal partners.
Organic nutrients
Formation of Pangea was NOT considered a likely contributing cause of this major event in animal history.
Cambrian diversification/explosion of animal body plans
An animal has two calcium carbonate shells and a horseshoe-shaped crown of ciliated tentacles used for filter feeding. Identify its phylum.
Brachiopoda
