Final answer:
Teosinte is considered to be an Obligatory Cultigen because it is completely dependent on humans for its survival and reproduction.
Step-by-step explanation:
Teosinte is considered to be an Obligatory Cultigen.
Obligatory Cultigens are plants that are completely dependent on humans for their survival and reproduction. They have undergone significant genetic changes through selective breeding and are unable to survive in the wild without human intervention.
Teosinte, which is the ancestor of modern corn, has been transformed over thousands of years by indigenous people in Mexico to produce maize as we know it today. Therefore, the statement that Teosinte is considered to be an Obligatory Cultigen is true.
