What are spore-forming protists?
Spore-Forming Protists are all Parasites that absorbs nutrients from their hosts. Plasmodium vivax is a kind of Spore-Forming Protist that causes Maleria. Maleria is a serious disease that is carried by mosquitos in tropical areas.
What is spore reproduction?
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.
How are spores formed?
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 is a spore in food?
Spores are bacteria and Fungi in a dormant state, where they are generally not actively metabolising. Some pathogens can form spores when in adverse condition i.e. severe heat or severe acidity but then become active when conditions are more favourable e.g. a product in the danger zone, between cooking and cooling.
Are spore-forming protists animal-like?
Animal-like protists called protozoa are single-celled consumers. Many are parasites. Protozoa are divided into four phyla (amoebalike, flagellates, ciliates, and spore-forming protists.
What are advantages of spore formation?
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.
What are the characteristics of spore bearing plants?
Spore plants are a group of plants that reproduce asexually and not by seeds, but by spores. These plants produce spores that are incredibly resistant to extreme environments that once landed germinate into a new plant.
What is a spore in food safety?
What kills spores in food?
Heating foods will kill all microbes – depending on the temperature. Most microbial cells will die at a temperature of 100 ºC. However, some bacterial spores will survive this and need temperatures around 130ºC to kill them. The heat treatments used in food production include pasteurisation, sterilisation and canning.
