All parts of nonvascular plants must be near water because they have: B. tiny roots.

<h3>What is photosynthesis?</h3>

Photosynthesis can be defined as a biological and chemical process through which living organisms such as green plants (autotrophs), transform light energy (sunlight) into stored chemical energy.

<h3>What is a nonvascular plant?</h3>

A nonvascular plant can be defined as a species of low-growing, non-flowering plant that lacks specialized conducting channels, deep roots or vascular tissues (xylem and phloem) for the transportation of nutrients and absorption of water.

Generally, nonvascular plants usually possess tiny roots and the the dominant stage of their life cycle is the photosynthetic gametophyte. Some examples of a nonvascular plant include the following:

  • Moss
  • Liverwort
  • Bryophyte

In conclusion, we can infer and logically deduce that all parts of nonvascular plants must be near water because they have tiny roots.
