Which algae are MOST closely related to plants?
green algae
In contrast to bacterial endospores, fungal spores have substantially less resistance to
heat
The ability to form endospores in bacteria within Bacillales, Clostridiales, and Lactobacillales suggests the genotype/phenotype evolved
only once in an ancestor to these three orders, due to the high number of genes required
