Bryophytes vs Pteridophytes
| Bryophytes | Pteridophytes |
|---|---|
| Bryophytes are non-vascular plants. | Pteridophytes are vascular plants. |
| The plant body is leafy or thalloid. | The plant body is differentiated into roots, stem and leaves. |
| No vascular tissues. | Vascular tissues are present. |
How is pteridophytes characterized and classified?
Pteridophytes (ferns and lycophytes) are free-sporing vascular plants that have a life cycle with alternating, free-living gametophyte and sporophyte phases that are independent at maturity. The body of the sporophyte is well differentiated into roots, stem and leaves. The leaves may be microphylls or megaphylls.
Which of the following features is related to pteridophytes?
Features of Pteridophytes Pteridophytes display differentiation. The plant body can be divided into true root, stem, and leaves. A saprophyte is the main plant body here. Some of the species belonging to this division have small leaves called the microphylls.
Which is not a character of pteridophytes?
Large spores are called megaspores while small spores are called microspores. Spores are formed by the sporophyte both in bryophytes and pteridophytes. Hence, option A is defines a character which is not same in bryophytes and pteridophytes. So, the correct answer is ‘Water requirement for fertilization’.
What are pteridophytes also called?
Pteridophytes are also called cryptogams. ‘Cryptogams’ is the term used for plants that do not form flowers and seeds. So, it is assumed that their reproduction is hidden as they produce spores.
What is the unique feature of Pteridophytes?
The unique feature of pteridophytes compared to other green plant groups is that they have both independent sporophytes and gametophytes. The zygotes are not necessarily subjected to a division depletion. They create sporophyte which is a multicellular body.
What is the basis of classification of Pteridophytes?
Hint: A pteridophyte is a free-sporing vascular plant with xylem and phloem. On the basis of nature and relation of leaf and stem vascular anatomy and position of sporangia, they are classified into four main classes – Psilopsida, Lycopsida, Sphenopsida and Pteropsida.
What is the unique feature of pteridophytes?
What are the characteristics of spermatophyta?
General characteristics of phylum spermatophyta
- The plant has roots, stems, leaves and seed bearing structures.
- They produce seeds.
- They have chlorophyll hence are photosynthetic.
- They have vascular tissue is highly developed with xylem tissue consisting of both xylem tissue and tracheids.
What is absent in pteridophytes?
Gametophyte of pteridophytes require cool, dry and shady places to grow. …
What are the differences between bryophytes and 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.
What are the characteristics of a Pteridophyta plant?
Pteridophyta Characteristics 1. Pteridophytes are considered as the first plants to be evolved on land: It is speculated that life began in the oceans, and through millions of years of evolution, life slowly adapted on to dry land.
Who are the members of the Pteridophyta group?
1. Members of this group are most primitive living vascular plants such as Selaginella, Lycopodium, Equisetum etc., and also fossil vascular plants such as Rhynia, Horneophyton, Asteroxylon, etc. 2.
Which is the most primitive class of Pteridophyta?
Pteridophyta is classified into four main classes: They are the most primitive. The stem is photosynthetic and dichotomously branched. Rhizoids are present. Leaves are mostly absent. The sporophyte is homosporous synangium. Examples- Psilotum and Tmesipteris. They are commonly known as club moss.
Which is the best description of a Pteropsida?
Pteropsida 1 Commonly known as a fern. 2 Well-differentiated plant body with roots, stem and leaves. 3 The sporophyte is homosporous or heterosporous. 4 Antherozoids are multiflagellate. 5 Examples- Pteris, Dryopteris, Adiantum
