Plant Interactions and Symbiosis

The video tutorial discusses the interactions among plants, focusing on symbiosis, specifically commensalism and parasitism. It explains how plants modify their growth patterns to meet their basic needs and provides examples of commensalism, such as steakhorn ferns and wild orchids growing on trees. The video emphasizes that these interactions do not harm the host plants, illustrating the concept of commensalism.
