A plant without chlorophyll would not be able to photosynthesise because chlorophyll serves to absorb sunlight, which is used to break apart the bonds in water during photosynthesis. A plant that is unable to photosynthesise is not able to create glucose, hence it would likely die unless it was receiving glucose through another source. This is because the plant relies on the energy it gets from breaking down glucose for important internal functions.
