Pls halp halp pls pls halp pls - how did the permian extinction affect insects?

Extinct, as were 50% of the Genera and 20% of families. [1] [3]

The massive extinction of the Devonian is one of the five great extinctions that have occurred in Earth's history, along with the mass extinctions of the Ordovician-Silurian, the mass extinction of the Permian-Triassic, the Triassic-Jurassic extinction, and the Cretaceous extinction However, there are authors who consider that the extinctions of the Devonian - in particular the extinction at the Frasnian-Famenian limit - were not in fact mass extinctions, but a loss of biodiversity caused by rates of extinction. Very low speciation. [10] [Note

Looy picked up a spruce cone. Pollen from the trees around us might be preserved inside. She believes that the Permian extinction was caused by acid rain following a massive release of volcanic gases. She wants to compare tree pollen from a modern forest killed by acid rain with fossil pollen found in Permian rocks.

framework and anchor for organelles

Explanation:

Cytoskeleton are made of three main filaments including actin filaments, microtubules and microfilaments. Microfilaments are flexible double strands of the protein actin  that are of different proteins which give  mechanical support. Important functions include:They lead the intracellular movement of organelles  and molecules .They stabilize mechanically the plasma membrane.

Microtubules are rigid hollow cylinders of the proteins α- & β-tubulin . They are responsible for the position and stability of ER and  Golgi-Apparatus . They help to divide & move chromosomes during mitosis  and also organize the growth of the cell wall . Actin filaments are robe like fibres of different proteins which give mechanical support.
