Question

Differentiate between Bryophytes and Pteridophytes.

Answer 1

Hint: 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.
