spore(redirected from Internal spore)
Also found in: Thesaurus, Medical, Encyclopedia.
1. 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.
2. A megaspore or microspore.
3. A dormant nonreproductive body formed by certain bacteria often in response to a lack of nutrients, and characteristically being highly resistant to heat, desiccation, and destruction by chemicals or enzymes.
intr.v. spored, spor·ing, spores
To produce spores.
1. (Biology) a reproductive body, produced by bacteria, fungi, various plants, and some protozoans, that develops into a new individual. A sexual spore is formed after the fusion of gametes and an asexual spore is the result of asexual reproduction
2. (Biology) a germ cell, seed, dormant bacterium, or similar body
(Biology) (intr) to produce, carry, or release spores
[C19: from New Latin spora, from Greek: a sowing; related to Greek speirein to sow]
n., v. spored, spor•ing. n.
1. the asexual reproductive body of a fungus or nonflowering plant.
2. the resting or dormant stage of a bacterium or other microorganism.v.i.
3. to produce or shed spores.
[1830–40; < New Latin spora < Greek sporá sowing, seed, akin to speírein to sow; compare sperm1]
var. of sporo-: teliospore.
1. A usually one-celled reproductive body that can grow into a new organism without uniting with another cell. Spores have only a single set of chromosomes. Fungi, algae, plants that do not bear seeds, and certain protozoans reproduce asexually by spores.
2. A similar one-celled body in seed-bearing plants that develops into either the embryo sac or a pollen grain.
3. A rounded, inactive form that certain bacteria assume under conditions of extreme temperature, dryness, or lack of food. The bacterium develops a waterproof cell wall that protects it from being dried out or damaged.
Past participle: spored
A small reproductive body from which a new organism can grow, such as in nonflowering plants, certain bacteria, algae, and fungi.
