Plants such as ferns and mosses are called nonflowering plants and produce spores instead of seeds. There is also another group called the Fungi, that include mushrooms, and these also reproduce by spores.
Which of the following reproduces spore formation?
Rhizopus, mushroom etc. , reproduce by spore formation. The three conditions favourable for spores to germinate and grow are as follows: Moisture. Optimum temperature.
Which of the following plants reproduce spores?
Ferns, mosses, liverworts and green algae are all plants that have spores. Spore plants have a different life cycle. A parent plant sends out tiny spores containing special sets of chromosomes. These spores do not contain an embryo or food stores.
Which plants reproduce by seeds and which by spores?
Mosses, ferns, and their relatives are plants that do not produce flowers but reproduce by means of SPORES. Most live in shady or damp habitats. CONIFERS are non-flowering plants that reproduce by making seeds.
What are examples of spores?
An example of a spore is a flower seed . A small, usually single-celled reproductive body that is resistant to adverse environmental conditions and is capable of growing into a new organism, produced especially by certain fungi, algae, protozoans, and nonseedbearing plants such as mosses and ferns.
How do plants reproduce by spores?
Plants that reproduce by spores
A parent plant sends out tiny spores containing special sets of chromosomes . These spores do not contain an embryo or food stores. Fertilisation of the spores takes place away from the parent, usually in a damp place. An embryo is formed and a new plant grows from it.
Where do spores come from?
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 the definition of spore formation?
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 are the advantages of spore formation?
Organisms do not waste their energy unnecessarily in producing male and female gametes. Large numbers of spores are produced in one sporangium. Spores do not require any medium for dispersal. They are rounded and very light in weight and hence can be easily transferred for germination.
How do spores reproduce asexually?
Asexual reproduction occurs either with vegetative spores or through mycelia fragmentation where the fungal mycelium separates into pieces and each piece then grows into a separate mycelium. Fungi imperfecti and deuteromycota lack an observable sexual cycle.
Can a plant grow without its seed?
Plants can grow without producing seeds . There are two general ways for plants to reproduce. ... The second way is called asexual or vegetative reproduction where plants develop offshoots, suckers from the roots, or simply allow one of its branches to trail along the ground and develop roots wherever it touches the ground.
Which plants can grow without seeds?
Some plants, like ferns and mosses , grow from spores. Other plants use asexual vegetative reproduction and grow new plants from rhizomes or tubers. We can also use techniques like grafting or take cuttings to make new plants.
What is a group of plants where pollen is stored in flowers?
Angiosperms : A division of the plant kingdom that includes all flowering plants; vascular plants in which double fertilization occurs resulting in development of fruit containing seeds. Divided into two major groups, monocotyledons and dicotyledons. Anther: The pollen-bearing organ at the apex of the stamen.
Can spores cause disease?
Spores are inhaled and deposited into the lung tissue, where they proceed to germinate and spread through lymph nodes, rapidly causing systemic disease , massive tissue damage, shock and death (14).
Which bacteria are spore forming?
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.
What is the main difference between spores and seeds?
| Seeds Spores | They are of two types based on the number of cotyledons, e.g. monocots produce seeds with single cotyledons and dicots produce seeds with two cotyledons. They are of two types: homosporous (identical spores or one type) and heterosporous (male and female spores or two different types). |
