Question: What Is The Name Of The Cone Like Spore Producing Structures In Horse Tails And Club Mosses?

What is the name of the structure used by club mosses to hold their spores?

In many species of club mosses, club -like projections or “candles” held above the small leaved, conifer-like stems are known as strobili (strobilus, singular form) and have structures called sporangia (sporangium). In other species, the sporangia are formed on certain leaves of the plant.

Is horsetail a Lycophyte?

Lycophytes, also known as the ‘fern allies’, are a group of roughly 1250 primitive plant species. The fronds of some species grow as large as 5 m long while others only reach 1 cm in length. Equisetum is a genus of ferns commonly known as the ‘horsetails’.

Is club moss a cone bearing plant?

They are typically found with fungi, algae, and similar organisms. A cone or strobilus, contains the reproductive organs of certain nonflowering plants or gymnosperms, (naked seeds) which include conifers (pine trees), club moss, and horsetails.

What is produced in the strobili of horsetails and club mosses?

Spores arise in the conelike strobili, at the base of the tiny leaves. The spores of club mosses produce a hermaphroditic plant, with male and female parts on the same plant. Spike mosses produce two kinds of spores, which germinate into male and female plants.

Does moss reproduce asexually?

Mosses reproduce by spores, which are analogous to the flowering plant’s seed; however, moss spores are single celled and more primitive than the seed. Mosses also spread asexually by sending out new shoots in the spring from last years plants as well as fragmentation.

Is Irish moss a bryophyte?

Other options: True moss belongs to class Bryopsida of division Bryophyta. Lichens are symbiotic association of algae with fungi found in moist habitat. Division Bryophyte exist in moist and aquatic environment called as amphibians of plant kingdom.

Which plant is known as horsetail?

Horsetail, ( genus Equisetum ), also called scouring rush, fifteen species of rushlike conspicuously jointed perennial herbs, the only living genus of plants in the order Equisetales and the class Equisetopsida.

Is a horsetail a Gymnosperm?

Horsetails are seedless vascular plants that reproduce with spores and are found in a moist environment. They have spores of two different sizes, microspores, and megaspores. Thus, the answer is option B: Ovules are not enclosed by the ovary wall in gymnosperms.

How does horsetail look like?

What does horsetail look like? “ The leaves of horsetails are arranged in whorls fused into nodal sheaths. The stems are green and photosynthetic, and are distinctive in being hollow, jointed and ridged (with sometimes 3 but usually 6-40 ridges). There may or may not be whorls of branches at the nodes” (Wikipedia).

What is the difference between cone bearing and spore bearing plants?

Difference. Cone-bearing plants have pollen and seeds. Spore-bearing plants produce no pollen or seeds. Cone-bearing plants produce spores and gametes in addition to pollen and seeds, however spore-bearing plants are limited to spores and gametes, and produce no pollen or seeds.

What plants are spore bearing and cone bearing?


  • SPORE BEARING PLANTS A plant that reproduces by bearing spores; also known as sporophyte.
  • FERNS a flowerless plant that has feathery or leafy fronds.
  • Vascular plants.
  • rhizomes The stem of sporophyte ferns.

Is Juniper a spore bearing plant?

Non-flowering plants which have seeds, bear them in cones, consisting of one or more bracts. Those not having seeds reproduce by spores. Examples of cone bearing plant families are pines, spruce, fir, cedar, red-woods, juniper, yew and more primitive than these, cycads.

Are Clubmosses vascular?

The clubmosses and their relatives are the most ancient group of vascular plants — plants with specialized tissue called xylem that transports water and nutrients throughout the plant.

Do club mosses have guard cells?

Club-mosses (Lycopodiales) are homosporous, but the genera Selaginella and Isoetes are heterosporous, with female spores larger than the male, and gametophytes forming entirely within the spore walls.

What are the two generations in mosses life cycle?

The life cycle of a moss, like all plants, is characterized by an alternation of generations. A diploid generation, called the sporophyte, follows a haploid generation, called the gametophyte, which is in turn followed by the next sporophyte generation.
