In biology, a spore is a unit of sexual or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores form part of the life cycles of many plants, algae, fungi and protozoa.View full answer
Keeping this in mind, What is a spore simple definition?
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 produced by bacteria, fungi, algae, and plants.
In this manner, What is spore with example?. The definition of a spore is a small organism or a single cell being that is able to grow into a new organism with the right conditions. An example of a spore is a flower seed. ... Any small organism or cell that can develop into a new individual; seed, germ, etc.
Likewise, people ask, How do you explain spores to a child?
A spore is a reproductive cell that can develop into a new individual without uniting with another reproductive cell. Spores are distinguished from gametes, which are reproductive cells that must unite with gametes of the opposite sex in order to form a new organism.
Is a spore a virus?
According to Bandea's hypothesis, the infected cell is the virus, while the virus particles are 'spores' or reproductive forms.
They also may contain significant amounts of mycotoxins. Diseases associated with inhalation of fungal spores include toxic pneumonitis, hypersensitivity pneumonitis, tremors, chronic fatigue syndrome, kidney failure, and cancer.
On a biological level, the main difference is that bacteria are free-living cells that can live inside or outside a body, while viruses are a non-living collection of molecules that need a host to survive.
Some of the organisms that produce spores include:
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).
Spore, a reproductive cell capable of developing into a new individual without fusion with another reproductive cell. ... Spores are agents of asexual reproduction, whereas gametes are agents of sexual reproduction. Spores are produced by bacteria, fungi, algae, and plants.
A spore is a cell that certain fungi, plants (moss, ferns), and bacteria produce. Spores are involved in reproduction. Certain bacteria make spores as a way to defend themselves. Spores have thick walls.
- The organism does not need male and female reproductive organs.
- 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.
Spores are an asexual form of reproduction; the plant or fungus doesn't need to mate with another plant or fungus to form these particles. A spore is typically a single cell surrounded by a thick cell wall for protection. Once the spores are formed, the organism releases them into the environment to grow and thrive.
(Entry 1 of 3) : a primitive usually unicellular often environmentally resistant dormant or reproductive body produced by plants, fungi, and some microorganisms and capable of development into a new individual either directly or after fusion with another spore.
Spores contain both male and female reproductive organs, which allows these plants to replicate themselves in a form of cloning.
In people allergic to mold, breathing in spores can trigger an asthma flare-up. If you have a mold allergy and asthma, be sure that you have an emergency plan in case of a severe asthma attack. Allergic fungal sinusitis. This results from an inflammatory reaction to fungus in the sinuses.
When mold spores are inhaled, immune system cells surround and destroy them. But people who have a weakened immune system from illness or immunosuppressant medications have fewer infection-fighting cells. This allows aspergillus to take hold, invading the lungs and, in the most serious cases, other parts of the body.
What is the treatment? It's almost impossible to avoid all contact with fungal spores, so treatment for mold in your lungs often consists of taking medications. Corticosteroids often help open your airways to make coughing easier. You may need to take them when daily or only when your symptoms flare.
Spore formation and life cycles
The gametophyte produces haploid gametes, which fuse to form a diploid zygotic sporophyte. Spores contain DNA and can develop into new organisms after dispersal. Spores are unicellular and haploid (having one-half of the genetic complement as have somatic, or body, cells).
The (macro) fungi that are dealt with in this website can be divided into two broad groups, called ascomycetes and basidiomycetes, depending on how their sexual spores are formed. ... The function of the fruiting bodies described in the TYPES OF FUNGI SECTION is to produce and disperse sexual spores.

Viruses are smaller than bacteria. Bacteria can survive without a host, although a virus can't because it attaches itself to cells. Viruses almost always lead to diseases (at a much higher rate than bacteria).
Other serious bacterial diseases include cholera, diphtheria, bacterial meningitis, tetanus, Lyme disease, gonorrhea, and syphilis.
