The various planets are thought to have formed from the solar nebula, the disc-shaped cloud of gas and dust left over from the Sun's formation.
They can’t live in dry areas because fungi need to be able to trap moisture since their broad tops can dry out
The life cycle stages of a plant would be seeds → germination→growth→maturity→pollination→fertilisation→seeds etc etc.
so I would say the life cycle stages not found in animals would be either pollination or germination.
