what is the similarity between the plants of the group Thallophyta Bryophyta and pteridophyta irrespective of the differences in their in their body structur?
Answers
In both, Thallophytes and Bryophytes, the plant body is thalloid, ie., despite the fact that Thallophytes are single celled and Bryophytes are multi-celled, the plant body is ribbon-like, and dichotomously branching, ie. the parent plant branches into two at the ends / apical region.
Both Divisions, Thallophyta and Bryophyta, are able to synthesize their own food from light or chemical energy, making them autotrophs or autotrophic in nature.
The many chloroplast pigments like Chlorophyll a, b, A, B, Carotenoid, Violaxantin, Xeaxantin and Leutin are similar in both Divisions.
Vascular tissues are absent. (Vascular tissues are tissues like xylem and phloem which are found in higher plants. They help in the conduction of food and water through the complex plant body of higher plants.)
Reserve food material is starch. (In higher plants, the food that is stored may be in the form of carbohydrates, fats, oils, etc. )
Roots, as seen in higher plants, are absent in both Thallophytes and Bryophytes.
Cellulose is the chief component of the cell wall in both.
The gametophyte (parent plant body / thalli) represent the dominant phase of the life cycle.
