Question

Give the differences between thallophyta and Bryophyta.
A) Thallophyta: Body is thallus like, not differentiated into root, stem and leaves.
     Bryophyta: Plants body is differentiated into leaf-like structure and rhizoids.
B) Thallophyta: Sex organs single-celled
     Bryophyta: Sex organs multicellular

C) Both A and B
D) None of these

Answer 1

Hint: Thallophyta is a division of the kingdom of plants, including basic types of plant life, displaying a simple plant body. Bryophyta, the classification of green plants, refers to embryos.

Complete Answer:

Sl.No	Thallophyta	Bryophyta
1.	In this kingdom of plants, most of them are marine.	Whereas in this type most of them are terrestrial and prefer areas that are damp and shady.
2.	The thallus consists of a single cell to uniseriate or branched well-formed filaments.	The thallus is not filamentous, except in the stage of protonema. It is composed of parenchymatous cells.
3.	There are no or ill-defined differentiations in tissues.	Tissue differentiation is well-defined and it is clearly visible.
4.	One of only a few chloroplasts is present in each cell. The chromatophores are found in other situations, instead of chloroplasts.	Many well-formed chloroplasts are present in each chlorophyllous cell.
5.	There are no stomata or pores	There are openings, or stomata.

So, the correct answer is option ‘C’.

Note: Both replicate by the creation of a spore. They are known as cryptogams since they can not see their reproductive organs. Bryophytes are thought to have originated from charophytes and are known to have been the first true plants to have ever originated. The Thallophyta group is divided into two subdivisions: Algae and Fungi.
