All animals are motile, which means: -they are capable of sexual or asexual reproduction -they have specialized tissues -they can move from place to place under their own power, at least during some life stages -they are multicellular eukaryotes

-they can move from place to place under their own power, at least during some life stages

Most mammals belong to this group, which gives birth to live young after completing gestation with a uterus attached to a placenta. Monotremes Marsupials Eutherians

Eutherians

All plants are photosynthetic. true/false

False

Which of the following statements about protist relationships is FALSE? Protists are all very closely related to one another. Some protists are more closely related to animals, plants, or fungi than they are to one another. Recent molecular systematics has placed members of the Protists in all six Eukaryotic supergroups. Before DNA analysis was available, protist relationships were determined based on anatomical similarities.

Protists are all very closely related to one another.

All protists are eukaryotes. true/false

True

As supported by recent molecular systematics, all plants are descended from a single common ancestor, most likely a green alga. true/false

True

An organism whose body parts are arranged so that only one plane of symmetry exists, and the organism can be divided into equal left and right halves displays ____________________ symmetry. asymmetrical bilateral radial identical

bilateral

A microbial community, consisting of multiple species, that is held together by a sticky secreted matrix and makes its members more robust than free-living prokaryotes is a ________________________. microbial mat stromatolite biofilm slime mold

biofilm

Many plants form symbiotic relationships with fungal species, which help the plant by channeling soil nutrients and water toward the plant roots and receive some products of photosynthesis in return. The name for this symbiosis is lichens commensal fungi mycorrhizae sporangia

mycorrhizae

Earliest lineage of land plants; no vascular system; reproduces by spores; includes mosses. angiosperms gymnosperms nonvascular plants seedless vascular plants

nonvascular plants

Which of the following groups are NOT prokaryotes? bacteria protists archaea all of these are prokaryotes

protists

Some protists are ecologically important because they are decomposers that feed on dead organisms and waste matter, which returns nutrients to the environment. Another name for this type of organism is a: saprobe parasite pathogen autotroph
