Need help with biology(angiosperm or gymnosperm plant)?

see its an angiospermic plant and it is a mono cot which is a sub type of angiospremic plant and it is a desert plant because the tough waxy epidemal cells are there in desert plant only!! The epidermis serves several functions, it protects against water loss, regulates gas exchange, secretes metabolic compounds, and (especially in roots) absorbs water and mineral nutrients. Woody stems and some other stem structures produce a secondary covering called the periderm that replaces the epidermis as the protective covering. An angiospermic plant has a taproot !!
