Step-by-step solution

Step 1. Information on bryophytes.

• The division bryophyte is one of the five divisions of the plant Kingdom along with thallophyte, pteridophyte, gymnosperms, and angiosperms.
• Bryophytes are non-vascular plants growing on land and they are further divided into three parts namely liverworts, hornworts, and mosses.
• The life cycle of bryophytes is haplo-diplontic since alteration of generation occurs between the haploid stage in the diploid stage.

Step 2. Explanation on the absence of roots in  bryophytes. 

Bryophytes do not have true roots as present in vascular plants instead they have a root-like structure called the rhizoid that not only absorb moisture, water, and other nutrients from its surrounding but also provides mechanical support to the plant.
