The plants constitute a major component of the planet earth, which all living things need to sustain their life. The early man being limited in all forms of endowments of humankind, made very little use of these plants. He therefore maintained a stable equilibrium with them. The modern man (Homo sapiens), with his endowments, has asserted himself over other living and non- living things and is making use of the plants in diverse ways. These diverse ways, are in addition to a number of other benefits other living things including human beings, derive from the plants. This paper dwells on the services to which humankind has put the plants in the diverse religions and culture of people in Nigeria. The paper besides reviewing the diverse roles of plants in diverse religions and cultures, also discusses the changes that are now being experienced in the interactions of humankind with the plants. Nigeria is part of the African region, where biodiversity is claimed to be concentrated. It therefore behoves the people of Nigeria, to conserve the plants, so that their sustainability, can be assured.
