An introduction to Tropism Most of the time when we think about a living organism the first thought our mind gives birth to is the idea of movement. If something (the biotic object) is performing an act of movement it is pronounced living. All living beings exhibit some sort of motion. This motion or movement …
The literal meaning of eutrophication is “well-nourished”. But this term brings a negative connotation when it is studied in the field of ecology and environmental sciences. Eutrophication is a situation in which an excessive growth of organisms on the surface of an aquatic body is observed due to the presence of an excessive amount of …
Introduction All the living cells are electrically neutral with having an equal number of positive and negative charges. The cells try their best to maintain this electrical neutrality. The cytoplasm of the cells contains different positive and negative species such as inorganic ions, organic ions, acids, proteins, etc. The concentration of all these substances is …
Introduction Neurons are the structural and functional units of the nervous system found in animals. They are responsible for bringing about the nervous coordination among the various organs found in the body. each neuron has a cell body and cellular processes. The cellular processes of neurons are interconnected via synapses. The information is carried by …
Introduction All the organs found in multicellular organisms are made up of two types of cells; parenchymal cells and supporting cells. The parenchymal cells are involved in performing the main function of that organ such as nephrons in kidneys and myocytes in the heart, etc. The supporting cells are responsible for maintaining the structure of …
Introduction Coordination among the different organs and organ systems in the body of animals is brought about by the nervous system. It is comprised of millions of neurons that are responsible for carrying messages in the form of nerve impulses from one part of the body to the other. These neurons have a cell body …
Introduction The nervous system consists of neurons and neuroglial cells. Neurons are the excitable cells that can generate an action potential when stimulated by an environmental stimulus or other neurons. Neuroglial cells are responsible for providing support to the neurons. Neurons consist of a cell body that gives rise to cellular processes. These cellular processes …
Introduction There is a certain competition between plants for the two: Gravitropism and phototropism. Gravitropism, as the name suggests is defined to be the differential plant growth in response to gravity. To make it a bit simpler, let us divide the word into two. Gravity means in response to gravity whereas tropism refers growth of …
Introduction Phototropism is to be defined as the tropic effect of the plant in response to the factor light. Let us break the word into two, ‘photo’ means light and’ tropism’ means turning to a direction in response to the stimulus. This process works in accordance with the other five different types of tropisms which …
Introduction When it comes to muscle, understanding its structural organization is necessary to understand physiology. If there’s altered physiology, then it will be termed Pathology. The sarcomere is highly organized, containing long cylindrical filaments called myofibrils that run parallel to the axis of the fibre. The dark bands on myofibrils are called A bands (anisotropic) …
