Question

Differentiate between THALLOPHYTES and BRYOPHYTES

Answer 1

Thallophyta (Algae):

1. They are mostly aquatic.

2 The thallus consists of a single cell to well developed uniseriate or branched filaments.

3. There is no or ill defined tissue differenti­ation

4. In each cell one or few chloropasts are present. In other cases instead of chloroplasts, the chromatophores are present.

5. The stomata or pores are not present

Bryophyta:

1. Mostly terrestrial and prefer damp and shady places.

2. The thalles is not filamentous except in protonema stage. It is made up of parenchymatous cells.

3. There is well defined tissue differenti­ation.

4. In each chlorophyllous cell many well developed chloroplasts are present.

5. The pores or stomata are present.

6. The rhizoids are present. They may be smooth walled, tuberculate or obliquely septate. The scales are also present.
