In plants, a reproductive cell that is capable of developing into a multicellular adult without fusion with another cell; spores are usually formed as the products of meiosis In land plants the spore is covered by a hard shell
A differentiated, specialized form that can be used for dissemination, for survival of adverse conditions because of its heat and dessication resistance, and/or for reproduction Spores are usually unicellular and may develop into vegetative organisms or gametes They may be produced asexually or sexually and are of many types (See 573)
The reproductive body of an organism which is capable of giving rise to a new organism either directly or indirectly A viable (able to live and grow) body regarded as the resting stage of an organism A spore is usually more resistant to disinfectants and heat than most organisms
Particular form of certain microbes that allows the organisms to survive in a dormant stage until conditions improve at which time the spores can germinate and the life cycle resumes
A minute grain or germ; a small, round or ovoid body, formed in certain organisms, and by germination giving rise to a new organism; as, the reproductive spores of bacteria, etc
Spores aren't seeds, but they serve much the same purpose There are two sorts of spores you may need to know about (1) Spores are the microscopic seed-like structures of fungi, which are easily carried away by wind, water, insects, and animals Morels, Boletes, and other mushrooms are all fungi, but there are some fungal species that cause disease in plants (like powdery mildew and rot) (2) On the underside of fern fronds, spores are found in spore cases Fern spores also serve as a sort of seed, carrying in them genetic material that can germinate and grow into another plant
a small usually single-celled reproductive body produced by many plants and some protozoans and that develops into a new individual; "a sexual spore is formed after the fusion of gametes"
The resting stage of a fungus capable of propagation Fall is a great time to rid your yard of spores One of the most important aspects of organic gardening is cleanliness All leaves and debris from the spring and summer should be cleaned up and properly composted
Spores are cells produced by bacteria and fungi which can develop into new bacteria or fungi. a cell like a seed that is produced by some plants such as mushrooms and can develop into a new plant (spora, from , , from speirein ). Reproductive cell capable of developing into a new individual without fusing with another reproductive cell. Spores thus differ from gametes, which must fuse in pairs in order to create a new individual. Spores are agents of nonsexual reproduction; gametes are agents of sexual reproduction. Spores are produced by bacteria, fungi (see fungus), and green plants. Bacterial spores serve largely as a resting, or dormant, stage in the life cycle, preserving the bacterium through periods of unfavorable conditions. Many bacterial spores are highly durable and can germinate even after years of dormancy. Fungal spores serve a function similar to that of seeds in plants; they germinate and grow into new individuals under suitable conditions of moisture, temperature, and food availability. Among green plants (all of which have a life cycle characterized by alternation of generations), spores are the reproductive agents of the nonsexual generation (sporophyte), giving rise to the sexual generation (gametophyte)
A reproductive structure, formed without the union of sexual cells, which can give rise to a new organism Fungi, algae and many other organisms produce spores rather than seeds
An asexual, usually single celled, reproductive body of plants such as fungi, mosses or ferns; a microorganism, as a bacterium, in a resting or dormant state (FM3-4)
Molds reproduce by means of spores Spores are microscopic; they vary in shape and size (2-100 micrometers) Spores may travel in several ways-they may be passively moved (by a breeze or waterdrop), mechanically disturbed (by a person or animal passing by), or actively discharged by the mold (usually under moist conditions or high humidity)
