Which evidence supports the endosymbiotic hypothesis for the origin of the mitochondrion?

We see the emergence of true roots and true leaves (macrophylls) in which group of plants.

Which evidence supports the endosymbiotic hypothesis for the origin of the mitochondrion?

The largest extinction event recorded in the fossil record was the Permian-Triassic extinction, which gave rise to the Mesozoic era. Nearly all multicellular life was eliminated. It is estimated that 96% of marine life and 70% of terrestrial animals went extinct.  What is one of the possible causes of that extinction event?

Which of the following are consdiered seedless vascular plants?

Cell walls of fungi are composed primarily of

According to the endosymbiotic theory, why was it evolutionarily adaptive for the larger, eukaryotic host cell to keep the engulfed bacterium that became the mitochondrion, rather than digesting it as food?

For many years scientists believed that almost all animal lineages burst into being during the Cambrian era (just after the end of the Precambrian super eon).  However, there have been many recent findings of animal-like fossils and “trace fossils” (fossils of an animal-like organisms movement) from the late Precambrian.  Which of the following best explains why it took so long to realize there was animal-like life in the Precambrian?

The mycelium of fungi are made up of these long, branching filaments. What are they called? Note: spelling counts.
