Answer: The tissue structure of the liverworts restricts them to a type of environment that affects their size.

Explanation:

Nonvascular plants, also called the Bryophytes in Kingdom Plantae, are simple plants that grow in damp places on land and as the name implies, are non vascular plants( that is, they lack vascular tissues). There are three types of nonvascular plants which includes:

--> Mosses

--> liverworts and

--> hornworts.

Liverworts are restricted to a particular size through the type of tissue they have ( non vascular) because it predisposes them to lack conducting vessels like the phloem and xylem found in vascular plants which aids in conducting water and food to various parts of the plants. Also they do not grow tall like the vascular plants because they lack the qualities that will enable them do so, such as roots, stems and leaves.

Nonvascular plants are low-growing, reproduce with spores, and need a moist or damp environment.
