Bacteria exert both deleterious and benefical effects on human life. Beneficial species liberate fertilizer elements for growing crops, destroy sewage and other wastes, and produce valuable chemicals. Some species are…
The Pteridospermales or Cycadofilicales are characteristic gymnospermous plants that bore fern-like foliage, which in turn bore seeds that were unprotected. Hence, they are known as seed ferns. Pteridospermales is a…
The Bennettitales (Cycadeoidales) are a fossil group found from the Triassic to the lower Cretaceous, but were predominant in the Jurassic period of the Mesozoic era in South America, North…
Sexuality in fungi is diverse and fascinating. In fungi, gradual degeneration of sexuality can be observed. Degeneration of sexuality means functional and structural degeneration of sex organs, leading to the…
Fungi are eukaryotic, spore-bearing microorganisms. They are heterotrophic (i.e., can’t produce their own food through photosynthesis) and digest food externally by releasing hydrolytic enzymes into their surroundings. Fungi have unicellular…
The classification of the fungi is a very challenging task since it presents various problems that originate from the differences of opinion of different workers. The situation becomes even more…
In humans, each heartbeat produces two distinct sounds known as the first and second heart sounds. These two, the loudest sounds of the heart, are easily detected clinically by a…
The cardiac cycle refers to the sequence of events that results in the continuous and rhythmic contraction and relaxation of the heart chambers. All the events in a cardiac cycle…
The members of the Xanthophyta or Heterokontae (class Xanthophyceae) are characterized by their yellow-green pigments, including xanthophylls, which distinguish them from other algae. They are commonly known as yellow-green algae.…
