Horizontal roots that anchor the plant

77
Q

What does homeosporous mean?

A

Plants produce one type of spore, produce sperm and eggs, and have motile sperm

78
Q

What does heterosporous mean?

A

Plants produce two types of spores, females produce eggs, males produce non-motile sperm

79
Q

In what order was there: O2 in the atmosphere, multicellularity, the origin of earth, the beginning of life, multicellularity, origin of eukaryotes, and the origin of prokaryotes?

A

Origin of earth, origin of life, first prokaryote, O2 in atmosphere, first eukaryote, and multicellularity

80
Q

What are the benefits of multicellularity?

A

Specialization, lower SA to volume ratio

81
Q

What are the costs of multicellularity?

A

Higher metabolic costs, longer generation time

82
Q

What is significant about the Cambrian explosion?

A

Many new phyla appear, new modes of locomotion, segmented bodies appear

83
Q

What caused the Cambrian explosion?

A

More O2 in the atmosphere increased metabolism and growth, Hox genes provided developmental flexibility, predator/prey relations causes a change in exoskeleton
