Our world today is populated by multicellular organisms, from big trees to climate-wrecking humans. This multicellularity arose independently in plants and animals. Both animals and plants cope differently with the challenges of corralling individual cells together to form a larger organism, such as the need to communicate and coordinate between cells, to share and transport nutrients, and to form specialized structures.
