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

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
