Historical illustration of Sphagnum reproductive structures: (C) mature sporophyte showing capsule and pseudopodium; (A) longitudinal section of developing archegonium; (B) cross-section of mature capsule showing spore chamber and air space. Sphagnum squarrosum is a monoicious species (having both male and female reproductive organs on the same ...
Sphagnum is a genus of approximately 380 accepted species [2] [3] of mosses, commonly known as sphagnum moss, also bog moss and quacker moss (although that term is also sometimes used for peat). Accumulations of Sphagnum can store water, since both living and dead plants can hold large quantities of water inside their cells; plants may hold 16 ...
Blue: A spore bearing a trilete mark – the Y-shaped scar. The spores are about 30–35 μm across. The spores are about 30–35 μm across. Palynology is the study of microorganisms and microscopic fragments of mega-organisms that are composed of acid-resistant organic material and occur in sediments , sedimentary rocks , and even some ...
The biochemical and genetic characterization of the Glomeromycota has been hindered by their biotrophic nature, which impedes laboratory culturing. This obstacle was eventually surpassed with the use of root cultures and, most recently, a method which applies sequencing of single nucleus from spores has also been developed to circumvent this ...
Sphagnum fimbriatum can be challenging to identify at first glance, as it may be mistaken for other Sphagnum species, particularly stunted forms of S. recurvum. However, several distinctive features aid in its identification. A key characteristic is its hard, conical stem bud, a feature shared only with S. teres and S. squarrosum.
Hygromorphy is a common mechanism of seed dispersal as the movement of dead tissues respond to hygrometric variation, [11] e.g. spore release from the fertile margins of Onoclea sensibilis. Movement occurs when plant tissue matures, dies and desiccates, cell walls drying, shrinking; [ 12 ] and also when humidity re-hydrates plant tissue, cell ...
Moss peat is made from Sphagnum. Commercial. Peat is a fuel produced from dried bryophytes, typically Sphagnum. Bryophytes' antibiotic properties and ability to retain water make them a useful packaging material for vegetables, flowers, and bulbs. [49] Also, because of its antibiotic properties, Sphagnum was used as a surgical dressing in World ...
Epilobium hirsutum — Seed head. In the broadest sense, dispersal occurs when the fitness benefits of moving outweigh the costs. There are a number of benefits to dispersal such as locating new resources, escaping unfavorable conditions, avoiding competing with siblings, and avoiding breeding with closely related individuals which could lead to inbreeding depression.
