The main features of Kingdom plantae are as follows:

1. They are multicellular, eukaryotic, immobile and chlorophyll-containing plants.
2. Their cells are with plastids and the cell wall is made up of cellulose.
3. They prepare their own food by the means of photosynthesis; hence they are called autotrophs. Some of them are, however, heterotrophs. Example: Parasitic ( Cuscuta )
4. They are vascular plants as they have vascular tissues i.e. xylem and phloem for conduction. However, Algae and Bryophytes lack them.
5. They store food in the form of starch.
6. They are either non-flowering or flowering plants.
