Fruits   among the  given names are :

Typeof Fruit                                               Name

Berry                                                      Tomato

Nut                                                         Acorn

Pepo                                                        Pumpkin , cucumber

Simplefruit                                             peas

Multiplefruit                                           Pineapple

Drupe                                                      Cashewnut

Monotropa uniflora    is   white   in  color   ,    as  it   lacks  photosynthetic pigment chlorophyll .

Due   to absence   of  chlorophyll    it cannot  photosynthesize   as   other   plants , & therefore is a parasitic.

It   derives    it’s  energy from   other   photosynthetic plants   by  parasitizing   fungi  which    form   symbiotic   association  with roots   of   higher  plants ( mycorhiza ).

It   is   a  heterotroph  , more  appropriately   myco - heterotroph .
