What is spore formation explain with an example?
The parent plant produces hundreds of reproductive units called spores. When the spore case of plant burst then the spores spread into air. Under favourable conditions they germinate and produce new plant. For Example: Rhizopus, mucor(fungi), ferns, mosses (bread mould)
What is the process involved in spore formation?
Formation of reproductive spores The process involves sporogenous cells (sporocytes, also called spore mother cells) undergoing cell division to give rise to spores. In meiotic sporogenesis, a diploid spore mother cell within the sporangium undergoes meiosis, producing a tetrad of haploid spores.
What is spore formation give two examples?
Answer: For example , Bacteria are the unicellular organisms reproduce by spore formation whereas fungi such as Rhizopus ( bread mould ) and Mucor, and non-flowering plants such as are multicellular organisms which reproduce by spore formation method. [ => Underlined part is your answer. i.e., Ferns and mosses.
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 spore formation Class 7 definition?
Spores are the asexual reproductive bodies. When the air-borne spores land on food (or soil) under favourable conditions (like damp and warm conditions), they germinate and produce new plants. Most of the fungi, and flowerless plants (such as ferns and mosses) reproduce asexually by means of spores.
How many types of spore formation are there?
Depending on the type of bacteria, four types of spores are produced. These include: Endospores: Endospores are the most common types of spores. They are typically produced by Clostridium (e.g. Clostridium botulinum), Bacillus (e.g. Bacillus anthracis) and Sporosarcina bacteria (e.g. Sporosarcina ureae).
Which plants reproduce by spore formation?
Plants that reproduce by spores Ferns, mosses, liverworts and green algae are all plants that have spores.
Where are spores formed?
sporangium
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 is spore formation class 10?
Spore Formation is a method in Asexual Reproduction. When Sporangia burst; minute single-celled, thin or thick walled structures called spores are obtained. Under suitable conditions, they develop into a new Plant. Reproducing using spores is an asexual method.
What is spore formation Class 10 Brainly?
Explanation: Spore formation is a method of asexual reproduction which is found in non flowering plants such as fungi (Rhizopus) and bacteria. In this method of reproduction, the parent plant produces hundreds of tiny spores which can grow into new plants.
What do organisms use spore formation?
Organisms use spores as a means of asexual reproduction. Spores are also formed in bacteria, however, bacterial spores are not typically involved in reproduction. These spores are dormant and serve a protective role by safeguarding bacteria from extreme environmental conditions.
What is the process producing spores?
The spores are haploid and are produced by mitosis. During times when conditions are unfavorable for development, the algae undergo sexual reproduction to produce gametes. These sex cells fuse to become a diploid zygospore. The zygospore will remain dormant until conditions become favorable once again.
Is spore formation an asexual reproduction?
Spore formation is a method of asexual reproduction which is found in non flowering plants such as fungi (Rhizopus) and bacteria. In this method of reproduction, the parent plant produces hundreds of tiny spores which can grow into new plants. The spores are the microscopic, tough and resistant bodies which are round in shape and can grow into a new plant under suitable conditions.
Who discovered spore formation in bacteria?
discovery by Cohn In Ferdinand Cohn …and germination of spores (called endospores) in certain bacteria, particularly in Bacillus subtilis .
