The Chloroflexi (Chlorobacteria) are a class of bacteria that produce energy through photosynthesis. They make up the bulk of the filamentous anoxygenic phototrophs
Ameboid movement is a form of movement especially characteristic of amebas and other unicellular forms; it is also found in many wandering cells of metazoans, such as white blood cells, embryonic mesenchyme, and numerous other mobile cells that move throu
Biotechnology can be seen as an imprecise term since the harnessing of any biological process could justifiably be called biotechnology.
The flower has acquired an unique position in our lives. Floriculture deals with growing or cultivation (large scale) of beautiful flowering plants.
A tissue is a group of similar cells (together with associated cell products) specialized for the performance of a common function.
Horticulture may be described as the practice of growing plants in a relatively intensive manner. This contrasts with agriculture, which, in most Western European countries, relies on a high level of machinery use over an extensive area of land
Plants appeared on land about 425 million years ago and the evolutionary history of the plant kingdom reflects increasing adaptation to the terrestrial environment. Plants have organs and organ systems.
Three different prokaryotic DNA polymerases are known, of which DNA polymerases I and II are meant for DNA repair and DNA polymerase IN is meant for actual DNA replication
Germplasm theory of Weismann was a very significant advancement in our understanding of heredity, since this was for the first time that a distinction between hereditary and environmental variations could be made on a sound basis.
Microorganisms isolated from different sources (soil, water and air) or genetic manipulation are cultured on growth media.
Protiens are polymers of amino acids joined by peptide bonds (proteins are therefore also known as polypeptides). The number and order of the amino acids contained in a particular protein are prescribed by the DNA sequence of that protein?s gene.
Atoms of certain metals will absorb and emit radiation of specific wavelengths when heated in a flame, in direct proportion to the number of atoms present.
Coenzymes are small organic molecules that function with thousands of different enzymes in all organisms, assisting in the catalytic processes needed for life. They often contain vitamins as components.
Bilateral nervous systems, the simplest of which occur in flatworms, represent a distinct increase in complexity over the nerve net of radiate animals.
A tree is a perennial woody plant. It is most often defined as a woody plant that has many secondary branches supported clear of the ground on a single main stem or trunk with clear apical dominance.
Discovery of the essentiality of nitrogen is often credited to de Saussure (1-3), who in 1804 recognized that nitrogen was a vital constituent of plants, and that nitrogen was obtained mainly from the soil.
