What are the general characteristics of bryophytes and Pteridophytes?

What are the general characteristics of bryophytes and Pteridophytes?

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.

What is the importance of Pteridophytes?

Pteridophytes commonly known as Vascular Cryptogams, are the seedless vascular plants that evolved after bryophytes. Besides being a lower plant, pteridophytes are economically very important. Dry fronds of many ferns are used as a cattle feed. Pteridophytes are also used as a medicine.

How are Pteridophytes classified?

Pteridophytes are the “spore bearing vascular plants” and also called as seedless vascular plants belong to the cryptogams. Tracheophyta are further divided into four main groups : Psilopsida, Lycopsida, Sphenopsida and Pteropsida. But it is not certain whether these are divisions or classes.

What is the habitat of Pteridophytes?

Most of the living pteridophytes are terrestrial, growing in moist and shady places. Some members are aquatic (Azolla, Marsilea, Salvinia) usually occurring in permanent ponds.

What is the meaning of Pteridophytes?

: any of a division (Pteridophyta) of vascular plants (such as a fern) that have roots, stems, and leaves but lack flowers or seeds.

How many classes of Pteridophytes do we have?

four classes

What called Cryptogams?

Non flowering plants or non seed producing plants or spore producing plants in the plant kingdom are called Cryptogams. Algae, Bryophytes and pteridophytes together called Cryptogams.

What are Cryptogams 11th class?

A cryptogam is a plant that reproduces with the help of spores. The word “Cryptogamae” implies ‘hidden reproduction’, referring to the fact that they do not produce any reproductive structure, seed, or flower and therefore, called ‘lower plants’, ‘spore plants’.

What are Phanerogams Class 9?

Answer: Phanerogams or spermatophyta are the most advanced type of plants bearing seeds. They have roots, stems, leaves and flowers. They include gymnosperms and angiosperms.

What are Phanerogams short answer?

Phanerogams are plants that have special structures for reproduction and generate seeds. In these plants, after the process of reproduction, seeds are formed that contain the embryo and stored food, which is used for the initial growth of the embryo, during germination of the seed.

What are Phanerogams name its two groups?

Phanerogams are the plants which have prominent and clear reproductive organs which produce seeds and are also flowering plants. Its two groups are Gymnosperms and Angiosperms.

What are the two main group of Phanerogams?

Overview. Phanerogams bear flowers and fruits after their maturity. It is divided into gymnosperm and angiosperm.

Why are Gymnosperm ovules naked?

Complete answer: In gymnosperms, the ovule is naked because the ovary wall is absent and therefore the ovules stay unprotected and naked. Normally the ovules are bound to parts of the inner side of ovary walls known as the placentae.

What are the three classes of Phanerogams?

The plant body of phanerogams are well-differentiated into three distinct parts – roots, stem, and leaves. They possess a well developed vascular system. In angiosperms, the seed is found enclosed in the seed coat whereas in gymnosperms the seeds are present without a seed coat and are present inside modified cones.

What is the definition of Gymnosperm?

Medical Definition of gymnosperm : any of a class or subdivision (Gymnospermae) of woody vascular seed plants (as conifers or cycads) that produce naked seeds not enclosed in an ovary and that in some instances have motile spermatozoids — compare angiosperm.

What is another word for Gymnosperm?

n. seed plant, spermatophyte, phanerogam.

What are the four types of gymnosperms?

The four modern-day groups of gymnosperms are Coniferophyta, Cycadophyta, Gingkophyta, and Gnetophyta.

What does the word Gymnosperm mean quizlet?

Gymnosperm means “naked seed” seeds are produced out in the open on cone scales. Seed cones are woody, pollen cones are produced in clusters at the tip of branches. You just studied 19 terms!

What grows on a Gymnosperm?

Gymnosperms (“naked seed”) are a diverse group of seed plants and are paraphyletic. Gymnosperm characteristics include naked seeds, separate female and male gametes, pollination by wind, and tracheids, which transport water and solutes in the vascular system.

Which of the following is an example of Gymnosperm?

Cycas

Where are Gymnosperm found?

Of some interest, gymnosperms include the tallest, the most massive, and the longest-living individual plants on earth. They are found throughout much of the earth, but form dominant vegetation in many colder and arctic regions.

What is the life cycle of a gymnosperm?

Gymnosperms are vascular plants that produce seeds in cones. Examples include conifers such as pine and spruce trees. The gymnosperm life cycle has a dominant sporophyte generation. Both gametophytes and the next generation’s new sporophytes develop on the sporophyte parent plant.

What is the life cycle of Pteridophytes?

The reproduction in pteridophytes takes place with the help of spores. Some pteridophytes give rise to two different types of spores – large, female spores called as megaspores and small, male spores called as microspores. Such pteridophytes are referred to as ‘Heterosporous’ pteridophytes.

What is the function of gymnosperms?

Uses. Gymnosperms have major economic uses. Pine, fir, spruce, and cedar are all examples of conifers that are used for lumber, paper production, and resin. Some other common uses for gymnosperms are soap, varnish, nail polish, food, gum, and perfumes.

What are the most common gymnosperms?

The conifers are the most common and abundant group of “gymnosperms” alive today. They are woody plants with scale-like or needle-like leaves.
