Final answer:
The incorrect adaptation for plants to life on land amongst the options given is a 'waxy cuticle on roots to prevent drying out.' Roots absorb water and nutrients and typically do not have a waxy cuticle, which is present in the aerial parts of plants to minimize water loss.
Step-by-step explanation:
The adaptation that is not a feature of plants in adapting to life on land is a “waxy cuticle on roots to prevent drying out.” Organisms moving from water to land faced challenges such as desiccation and the need to obtain water and nutrients from the soil, and they evolved various ways to handle these. The vascular system is one such adaptation, allowing for the internal movement of water and nutrients throughout a plant's body. Additionally, the development of a protective cuticle on leaves and the protection of the embryo from drying out were critical in preventing desiccation. However, roots generally do not contain a waxy cuticle; their role is to absorb water and nutrients, and the waxy cuticle is an adaptation associated with aerial parts of plants to reduce water loss.
