Which life cycle stage is found in plants but not animals?
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.
Plants and animals both are eukaryotes but they differ in many aspects like animals can migrate around, while plant stays rooted, plants can make their food while animals depend on others for their meals.
Therefore, the plants have a haplodiplontic life series which is lacking in the animals.
