There are 5 things that are important to grew plants, water, sunlight, soil, heat and air.
Most plants need water often but not too much, because too much water may drown the plant. To prevent that, you could drill a hole at the bottom of a cup.
All plants need photosynthesis to survive, and photosynthesis only happens in sunlight. Sunlight also provide the heat.
Plants needs soil to survive, too, because soil provide food to plant, so soil must be nutritious and suitable for this plant.
Plants needs air to breathe, and need carbon dioxide to produce oxygen.
