A graph key for a bean plant could include water, light, and temperature. These are important factors that influence the growth and development of bean plants. Without these key elements, the graph may not accurately represent the conditions necessary for optimal bean plant growth.
Other important variables to include in the graph could be nutrients, soil quality, and pH levels. These factors also play a significant role in the growth and development of bean plants and should be included in the key to provide a comprehensive understanding of the optimal conditions for bean plant growth.
