Тезаурус:
- In bottle-wrack, on the other hand, the most recent common ancestor of all the cells in a plant is no older than the spore that provided the plant's bottlenecked beginning.
- Spores do not need to be killed in normal operational practice as the infectivity of the common spore former, Clostridium perfringens , occurs when the vegetative cell is ingested and converts to a spore.
- Ingestion of the spore is harmless.
- A spore which lands on wood with a moisture content of 20-;25 per cent in a still and stuffy atmosphere where the temperature is between 7 and 27C (44 and 80F) can germinate and then throw out hollow strands known as hyphae.
- The so-called basal cells of the two-celled spore point toward the tiny opening of the perithecium, the ostiole, and newly-formed asci in the lower part of the perithecium push the maturing ascospores towards the ostiole.
- If the spore did not, they will not.
- All cells in a daughter plant are descended from a single spore cell, so all cells in a given plant are closer cousins (or whatever) of one another than of any cell in another plant.
- If that spore contained the mutant gene, all the cells of the new plant will contain the mutant gene.
- To be really sure that one is dealing with a fossil fern it should be possible to see the spore cases, because other kinds of plants can produce fern-like foliage.
- Their use is therefore better suited to environments such as the rhizosphere/soil, protected crops, or tropical conditions ( eg paddy fields), where the water potential is likely to be more amenable to spore germination and growth.
- Its life-cycle starts with a spore, of which there are countless millions in the atmosphere.
- As is commonly found, maturity estimates based on spore colour and vitrinite reflectance (R) by different Laboratories have given varying results (Dembicki 1984).
