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.

4) Thallophyta, Bryophyta and Pteridophyta, all reproduce by spore formation. They are known as cryptogams as their reproductive organs cannot be seen.

5) Types of Biogeochemical Cycles

Biogeochemical cycles are basically divided into two types:

Gaseous cycles  – Includes Carbon, Oxygen, Nitrogen, and the Water cycle.
