Do all plants have similar parts?

While all plants share some basic structures, such as roots, stems, and leaves, not all plants have the same parts or the same arrangement. For example, some plants, like cacti, may have modified leaves that serve as spines, while others, like ferns, reproduce using spores instead of seeds. Additionally, some aquatic plants may lack traditional structures altogether. Thus, while there are commonalities, plant diversity leads to a wide variety of forms and functions.
