Spore bearing plants are algae, fungi, bryophytes, and pteridophytes. They reproduce asexually by spores produce mostly in sporangia. Spores are resistant to adverse environmental conditions and germinate into a new plant in suitable conditions.

What are the characteristics of spores?
In plants, spores are usually haploid and unicellular and are produced by meiosis in the sporangium of a diploid sporophyte. Under favourable conditions the spore can develop into a new organism using mitotic division, producing a multicellular gametophyte, which eventually goes on to produce gametes.
What are 2 characteristics of spores?
Spore color, shape, size, and ornamentation are among the more constant characteristics used in species descriptions. Spores generally are globose, free as single units or aggregated into loose or tight clusters (Fig.
What is spore bearing?
Definitions of spore-bearing. adjective. bearing spores instead of producing seeds. Synonyms: flowerless, nonflowering. without flower or bloom and not producing seeds.
What animals have spores?
Spores are reproductive cells in plants; algae and other protists; and fungi. They are typically single-celled and have the ability to develop into a new organism. Unlike gametes in sexual reproduction, spores do not need to fuse in order for reproduction to take place.
What are the characteristics of spore bearing plants?
Spore bearing plants are mostly flowerless. They produce spores and spores are much smaller than seeds in seeded plants. Spore bearing plants are algae, fungi, bryophytes, and pteridophytes. They reproduce asexually by spores produce mostly in sporangia.
What are characteristics of bacterial spores?
Bacterial spores are one of the most resistant life forms known to date, being extremely tolerant against various stresses such as heat, chemicals, and harsh physical conditions. One of the signature properties of spores is heat resistance.
What are spores for Class 5?
Answer: Spore, a reproductive cell capable of developing into a new individual without fusion with another reproductive cell. ... Spores are agents of asexual reproduction, whereas gametes are agents of sexual reproduction. Spores are produced by bacteria, fungi, algae, and plants.
Which is an example of spore bearing plant?
Spores are most conspicuous in the non-seed-bearing plants, including liverworts, hornworts, mosses, and ferns. In these lower plants, as in fungi, the spores function much like seeds. ... In ferns, spores are contained within cases called sporangia that are located on the underside of leaves.
What are spores Class 12?
Hint: Spores are primary agents of asexual reproduction. They are reproductive cells that are capable of developing into new individuals through asexual reproduction, i.e., without fertilizing with another reproductive cell. Complete answer: Spores are produced by fungi, algae, plants and bacteria.
What is a spore-bearing leaf?
A leaf that bears sporangia (spore-producing structures) is called as sporophyll. They vary greatly in structure. In ferns, the sporophylls are the normal foliage leaves, produce clusters of sporangia, known as sori.
Which is the spore-bearing bacteria?
Spore-forming bacteria include Bacillus (aerobic) and Clostridium (anaerobic) species. The spores of these species are dormant bodies that carry all the genetic material as is found in the vegetative form, but do not have an active metabolism.
How does spore-bearing plants reproduce?
When weather conditions are ideal, some ferns, algae, moss and even fungi, release spores into the air, often carried by the wind, by insects or birds until they land. Spores contain both male and female reproductive organs, which allows these plants to replicate themselves in a form of cloning.
What are spores fungi?
Fungal spores are microscopic biological particles that allow fungi to be reproduced, serving a similar purpose to that of seeds in the plant world. ... There are thousands of different fungi in the world which are essential for the survival of other organisms.
How do spores spread?
Being so small and lightweight, spores can easily move unseen in the air currents, and most fungal spores are spread by the wind. ... Some spores are also spread by water droplets from rain or in streams, and others need help from animals such as flies.
