Question: Differentiate between Bryophytes and Pteridophytes....
Differentiate between Bryophytes and Pteridophytes.
Explanation
Solution
Bryophytes are nonvascular plants producing flowers and seeds. Around 20,000 species of bryophytes have been found to date. Pteridophytes are vascular plants which do not produce flowers or seeds. They're also known as cryptograms. It includes a variety of true ferns. They've got leaves, stems, and roots.
Complete answer:
Bryophytes | Pteridophytes |
---|---|
They are non vascular plants | They are vascular plants |
The body of the plant is leafy or thalloid | The body of the plant is differentiated into roots stems and leaves |
No vascular tissues | Vascular tissues are present |
Rhizoids help in anchorage | Roots help in anchorage |
The gametophyte is dominant | The sporophyte is dominant |
Antheridium is stalked | Antheridium is sessile |
Cells are haploid | Cells are diploid |
Example:Mosses , liverworts | Example : Ferns , spikemosses |
Hypodermis is made up of collenchymatous cells | Hypodermis is made up of sclerenchymatous cells |
It is differentiated into cortex , endodermis pericycle and pith in the ground tissue | Ground tissue is not differentiated , it is a continuous mass of parenchyma. |
Starch sheath is present | Starch sheath is absent |
Pith is present | Pith is absent |
The walls of archegonial is 5-6 rowed | The walls of archegonial is 4 rowed |
It is dioecious | It is monoecious |
It is homosporous | It is heterosporous |
Leaves if present are microphyllus | Leaves if present are macrophyllus or microphyllus |
They can reproduce only with water | They can reproduce in the absence of water |
Note: Pteridophyta is one of the oldest groups of plants in the Plant Kingdom. They evolved much earlier than the angiosperms. They are one of the very first "true" plants to adapt to life on earth.Bryophytes are very simple plants. They are the simplest plants to grow on the land. There are three different forms of bryophyte. These are mosses, liverworms, and hornworms.
