Answer 1

26. Lack of roots, lack of sunlight, lack of conducting tissue

Mosses are small plants belonging to division bryophyta. They lack true roots and the reduced types of roots they have are called rhizoids.

They are small because they grow in shady areas where sunlight is very less.

They do not have any conducting cells because conduction takes place with the help of water only.
