Spores characteristics
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. Bacterial spores are not part of a sexual cycle, but are resistant structures use… WebBacillus cereus is a spore forming bacterium that produces toxins that cause vomiting or diarrhoea. Symptoms are generally mild and short-lived (up to 24 hours). B. cereus is commonly found in the environment (e.g. soil) as well as a variety of foods. Spores are able to survive harsh environments including normal cooking temperatures.

WebSpores are rusty-looking present underside the tips of the fern leaves. These spores disperse through wind, water or air current. Later, spores fall onto different substratum. In favourable conditions, the spore germinates and develop the fern gametophyte. During this stage, male and female sex organs develop, and fertilization occurs. WebSpore characteristics. Plants generally reproduce with spores or seeds, meaning those will be what germinates in a disaster's aftermath. But spores have advantages over seeds in the environmental conditions produced by a disaster.
