Spore | Definition, Types, & Examples | Britannica
spore, a reproductive cell capable of developing into a new individual without fusion with another reproductive cell. Spores thus differ from gametes, which are reproductive cells that must fuse in pairs in order to give rise to a new individual. Spores are agents of asexual reproduction, whereas gametes are agents of sexual reproduction.
Spore - Wikipedia
In biology, a spore is a unit of sexual (in fungi) or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. [1] Spores form part of the life cycles of many plants , algae , fungi and protozoa . [ 2 ]
What are Spores? Definition, Types, Structure and Life Cycle

Bacterial spore germination receptors are nutrient-gated ion ... - Science
2023年4月27日 · Bacterial spores resist antibiotics and sterilization and can remain metabolically inactive for decades, but they can rapidly germinate and resume growth in response to nutrients. Broadly conserved receptors embedded in the spore membrane detect nutrients, but how spores transduce these signals remains unclear.
Spore Formation - Method, Diagram and Examples - BYJU'S
Spores are haploid unicellular bodies that are produced as a result of sexual or asexual reproduction in eukaryotic organisms such as algae, bacteria, fungi and some plants. Read this article to find a diagram and examples of spore formation, only at BYJU’S.

2023年2月2日 · Sporulation or spore formation is the process of producing spores from the actively dividing (vegetative) cells. They are commonly found in bacteria, fungi, protozoa, and some plants such as ferns and mosses. The term ‘spore’ comes from the Greek word for seed.
Bacterial Spore - an overview | ScienceDirect Topics
Bacterial spores (such as Bacillus, Clostridium, and Desulfotomaculum) are small oval or spherical structures that are very resistant to high temperatures, radiation, desiccation, and chemical agents. When they are formed intracellularly, they are called endospore. The bacterial cell that gives the spore is called the vegetative cell.
BACTERIAL SPORES - #1 Microbiology Resource Hub
Spore formation aids in the spread or transmission of bacteria. It helps bacteria to survive harsh environmental conditions such as nutrient depletion and moisture depletion. Spore formation play critical role in the pathogenicity and toxicity of some pathogenic bacteria e.g. B. anthracis, B. cereus, C. tetani, and C. botulinum amongst others.

2014年12月16日 · In flowering plants, sporogenesis is initiated in both male and female reproductive tissues by the differentiation of sub-epidermal cells in the anther and ovule primordia, called archesporial...
What are Spores? (with pictures) - AllTheScience
2024年5月21日 · A spore is a unit of asexual reproduction adapted to spending a long period of time in unfavorable conditions before developing into an offspring of the plant, algae, fungi, or protozoan that created it. They are somewhat like seeds, but contain fewer nutrients, and are used by groups besides plants.
