Thallophytes' heterotrophy and dicotyledonous plant venation
Thallophytes are not necessarily heterotrophic due to the lack of chlorophyll; they include both autotrophic and heterotrophic organisms like algae and fungi.
Dicotyledonous plants typically have leaves with reticulate venation instead of parallel venation. Reticulate venation forms a network of veins unlike the parallel arrangement seen in monocots.
