What are the differences between the bryophytes and the pteridophytes?
Bryophytes are embryophytes that are non-vascular i.e., they have no xylem and phloem. Pteridophyte are vascular plants i.e., plants with xylem and phloem, that reproduce and disperse via spores. The dominant phase in bryophyte is gametophyte while the dominant phase in pteridophyte is sporophyte.
What is the difference between bryophytes pteridophytes and gymnosperms?
The key difference between these three groups is the habitat where they are grown. Bryophytes are adapted to grow in amphibious environments; Pteridophytes are adapted to terrestrial environments which are a moist and shady while, Gymnosperms are fully adapted to terrestrial environments.
How many feature S is are common between bryophytes and pteridophytes?
Similarities between Bryophytes and Pteridophytes Ø Both possess distinct Gametophytic and Sporophytic generations. Ø Both groups show heteromorphic alternation of generation. Ø Rhizoids are present in Bryophytes and Pteridophytes. Ø Stomata or pores are present in both groups for gaseous exchange.
Which of the following feature is common between bryophyte and pteridophyte?
Bryophytes vs Pteridophytes
| Bryophytes | Pteridophytes |
|---|---|
| No vascular tissues. | Vascular tissues are present. |
| Rhizoids are present for anchorage. | Roots are present for anchoring. |
| The gametophyte is dominating. | The sporophyte is dominating. |
| Anthredium is stalked. | Anthredium is sessile. |
Which of the following is common features for both bryophytes and pteridophytes?
How many feature are common in bryophytes and pteridophytes?
a) Absence of roots. b) Requirement of water for fertilization. c) Presence of vascular tissue. d) Presence of independent sporophyte and independent gametophyte.
What are the differences between Division bryophytes and division pteridophytes?
Bryophytes: Bryophytes are embryophytes that do not possess a true vascular tissue. Pteridophytes: Pteridophytes are vascular plants that reproduce via spores. Bryophytes: Bryophytes live in moist, shady places. Pteridophytes: Pteridophytes live in terrestrial environments.
How different are pteridophytes and bryophytes regarding with substance transport?
Pteridophytes are tracheophyte vascular plants i.e. they have tissues specialized in conduction of water and nutrients. Bryophytes are nonvascular plants. In pteridophytes therefore the substance transport is done through vessels and in bryophytes that transport occurs by diffusion.
Which of the following is a common feature among bryophytes pteridophytes and gymnosperms?
The common feature among Bryophytes, Pteridophytes, Gymnosperms and Angiosperms is. All have flagellated male gametes.
What are absent in pteridophytes?
Companion cells and sieve tubes are absent in pteridophytes. B. Gametophyte of pteridophytes require cool, dry and shady places to grow.
Why are pteridophytes better adapted to dry land than bryophytes?
Answer and Explanation: Pteridophytes are better adapted to dry land than bryophytes because they have a vascular system for conducting water from the soil to aerial parts…
What is the difference between sporophytes phase of bryophytes and pteridophytes?
Sporophytes phase of bryophytes depends on gametophyte while sporophyte phase of Pteridophytes is independent. Sporophyte phase of bryophytes is highly reduced while in Pteridophytes, gametophyte phase is highly reduced.
What are pteridophytes?
Pteridophytes or Pteridophyta are vascular plants (plants with xylem and phloem) that reproduce and disperse via spores. Because they produce neither flowers nor seeds, they are referred to as cryptogams.
What is the difference between pteridophytes and botanical snakes?
While pteridophytes are specially considered as first land plants, containing xylem and phloem tissues, they are also called ‘botanical snakes’ as they evolved after bryophytes which are said to be as ‘botanical amphibians’. Both of them are important from nature’s point of view, as they play their vital role in maintaining the ecological balance.
How old are Bryophyta and Pteridophyta?
Both Bryophyta and Pteridophyta have a lineage running back to four hundred million years, as suggested by fossil records. There is evidence suggesting that there existed treelike ferns as tall as 36.5 meters, known as Lepidodendron, an ancestor of modern club mosses.
