Answer 2

Answer:

The plants without root, stem, leaf and flowers are the bryophytes and the plants without ‘chlorophyll’ are the heterotrophic or the parasitic plant.  

Explanation:  

The bryophytes are the most primitive classification of plants after the algae, their body is not differentiated into ‘root stem’ and ‘leaves’, and they are majorly amphibious plants that live near the ‘water bodies’. The plants that lack chlorophyll cannot prepare their ‘own food’ and therefore they are considered as parasitic plants.
