Sound Reproduction System

Sexual Reproduction ... Sexual reproduction is the primary method of reproduction for the vast majority of macroscopic organisms, including almost all animals and plants... Evolutionary thought proposes several explanations for why sexual reproduction developed out of former asexual reproduction... Also, sexual reproduction allows for the "ratcheting" of evolutionary speed as one clade competes with another for a limited resource...

Plant Sexuality ... Among all living organisms, flowers, which are the reproductive units of angiosperms, are the most varied physically and show the greatest diversity in methods of reproduction of all biological systems... Plants that are not flowering plants (green alga, mosses, liverworts, hornworts, ferns and gymnosperms such as conifers) also have complex interplays between morphological adaptation and environmental factors in their sexual reproduction... The complexity of the systems and devices used by plants to achieve sexual reproduction has resulted in botanists and evolutionary biologists using numerous terms to describe physical structures and functional strategies...

Vegetative Reproduction ... Although most plants normally reproduce sexually, many have the ability for vegetative propagation, or can be vegetatively propagated if small pieces are subjected to chemical (hormonal) treatments. This is because meristematic cells capable of cellular differentiation are present in many plant tissues...

Sporogenesis ... Examples are the conidial fungi Aspergillus and Penicillium, for which mitospore formation appears to be the primary mode of reproduction...

Fragmentation (reproduction) ... If the splitting occurs without the prior preparation of the organism, both fragments must be able to regenerate the complete organism for it to function as reproduction... Fragmentation is as a method of reproduction is seen in many organisms such as filamentous cyanobacteria, molds, lichens, many plants, and animals like sponges, acoel flatworms, some annelid worms, and sea stars...

Budding ... Since the reproduction is asexual, the newly created organism is a clone and is genetically identical to the parent organism...

Reproduction ... Sexual reproduction typically requires the involvement of two individuals or gametes, one each from opposite type of sex... Asexual reproduction Asexual reproduction is the process by which an organism creates a genetically similar or identical copy of itself without a contribution of genetic material from another individual... Other ways of asexual reproduction include parthenogenesis, fragmentation and spore formation that involves only mitosis...

Postmodern Art ... There are several characteristics which define the term 'postmodern' in art; these include bricolage, the use of words prominently as the central artistic element, collage, simplification, appropriation, performance art, the recycling of past styles and themes in a modern-day context, as well as the break-up of the barrier between fine and high arts and low art and popular culture. Use of the term The predominant term for art produced since the 1950s is "contemporary art"...

Semelparity And Iteroparity ... In truly semelparous species, death after reproduction is part of an overall strategy that includes putting all available resources into maximizing reproduction, at the expense of future life (see "Trade-offs", below)...

Allogamy ... By contrast, autogamy is the term used for self-fertilization. In humans, the fertilization event is an instance of allogamy...

Plant Reproduction ... Natural vegetative reproduction is mostly a process found in herbaceous and woody perennial plants, and typically involves structural modifications of the stem or roots and in a few species leaves... Most plant species that employ vegetative reproduction do so as a means to perennialize the plants, allowing them to survive from one season to the next and often facilitating their expansion in size... A plant that persists in a location through vegetative reproduction of individuals constitutes a clonal colony, a single ramet, or apparent individual, of a clonal colony is genetically identical to all others in the same colony...

Fission (biology) ... Binary fission of prokaryotes Prokaryotic fission, which is binary fission, is a form of asexual reproduction and cell division used by all prokaryotes, (bacteria and archaebacteria), and some organelles within eukaryotic organisms... This process results in the reproduction of a living prokaryotic cell (or organelle) by division into two parts that each have the potential to grow to the size of the original cell (or organelle)...

Parthenogenesis ... The term is sometimes used inaccurately to describe reproduction modes in hermaphroditic species that can reproduce by themselves because they contain reproductive organs of both sexes in a single individual's body...

Art History ... As a term, art history (also history of art) encompasses several methods of studying the visual arts; in common usage referring to works of art and architecture. Aspects of the discipline overlap...

Apomixis ... In flowering plants, the term "apomixis" is commonly used in a restricted sense to mean agamospermy, i.e. asexual reproduction through seeds...
