Chromomycosis

Chromomycosis, or Chronic subcutaneous mycosis, is a severe fungal infectious disease that infects the skin’s subcutaneous tissue. A diverse group of dematiaceous or black fungi cause chromomycosis. Dematiaceous fungi are the heterogeneous fungal group, which usually form lesions or abscess in the subcutaneous tissue. Interaction of host tissue with the fungus shows a non-specific kind …

Respiration in Plants

Respiration in plants refers to a process in which a plant utilizes atmospheric oxygen to oxidize glucose and other respiratory substrates like fats or proteins. Respiratory substrates are high energy biomolecules that produce energy, carbon dioxide, and water due to the C-C bond breaks. Plants undergo cellular respiration in the presence or absence of light. …

Germination of Plant

Germination of a plant refers to a phenomenon in which a seed germinates to form a new seeding or plant. The germination process results in the emergence of the radicle (primary root) and plumule (primary shoot). Before germination, the seed remains dormant in the soil. Then, under favourable conditions (optimum temperature, oxygen, light, water etc.), a …

Anther

The anther is a part of the flower’s male reproductive system or stamen. It carries the reproductive structures or the male gametes (pollen grains), which germinate and cause the fertilization of an ovule. A male reproductive part of a flower typically consists of two elements (filament and anther). A filament appears as a long, slender …

Pollination in Flower

Pollination in a flower is a transferring mechanism of pollen grains from the anther (flower’s male reproductory part or stamen) to the stigma (flower’s female reproductive part or gynoecium). It is the primary stage that results in the flower’s fertilization. The passage of pollen grains from an anther to a stigma occurs via pollinating agents …

Bilayer Cell Membrane

The bilayer cell membrane is a membranous structure, which consists of two phospholipid layers. Thus, a cell membrane also refers to a phospholipid bilayer membrane composed of many phospholipid molecules. A structure of a phospholipid molecule consists of a hydrophilic head, a phosphate molecule, a glycerol molecule and two hydrophobic fatty acid tail. The phospholipid …

Clostridium botulinum

Clostridium botulinum is a clinically significant bacteria, which causes a sporadic but severe disease called “Botulism”. It produces a particular type of exotoxin that affects the nervous system by inhibiting the neuromuscular junction’s activity. Therefore, the botulinum toxin behaves as a neurotoxin, which blocks the release of a neurotransmitter (acetylcholine). Acetylcholine is a chemical compound …
