How are ferns similar to complex plant?

Ferns are similar to complex plants in that they are both vascular plants, meaning they have specialized tissues for transporting water and nutrients. They reproduce via spores rather than seeds, but like many complex plants, they exhibit alternation of generations in their life cycle. Additionally, ferns share the presence of chlorophyll for photosynthesis, allowing them to produce their own food. Overall, both ferns and complex plants play significant roles in their ecosystems and demonstrate similar biological functions.
