Mitosis is a type of cell division that forms two identical daughter cells from one parent cell. During mitosis, the chromosomes in the nucleus are divided into two equal sets, each of which is then moved to one of the two daughter cells. Meiosis is another type of cell division that produces four daughter cells …
Cell growth is the process of increasing the size of a cell, while cell division is the process of dividing a cell into two daughter cells. The two processes are closely related, as cell growth is necessary for a cell to divide. During cell growth, the cell increases in size and volume, and the cell …
സസ്യങ്ങൾ നിശ്ചലമാണെന്ന് നമുക്ക് തോന്നാറുണ്ടെങ്കിലും, അവയ്ക്ക് ചുറ്റുപാടുകളോട് പ്രതികരിക്കാനും അനുയോജിപ്പിക്കാനും കഴിയും. ഈ പ്രതികരണങ്ങളിൽ പ്രധാനപ്പെട്ട ഒരു വിഭാഗമാണ് ട്രോപ്പിക ചലനങ്ങൾ. ട്രോപ്പിക ചലനം എന്താണ്? ഒരു പ്രത്യേക ഉത്തേജനത്തിന്റെ ദിശയെ അനുസരിച്ച് സസ്യങ്ങളുടെ ഭാഗങ്ങൾ വളരുന്നതോ ചലിക്കുന്നതോ ആയ പ്രതിഭാസമാണ് ട്രോപ്പിക ചലനം. ട്രോപ്പിക ചലനങ്ങളുടെ തരങ്ങൾ ഫോട്ടോട്രോപിസം: പ്രകാശത്തോടുള്ള സസ്യങ്ങളുടെ പ്രതികരണം. തണ്ടുകൾ സാധാരണയായി പ്രകാശത്തെ അഭിമുഖീകരിച്ച് വളരുന്നു (പോസിറ്റീവ് ഫോട്ടോട്രോപിസം). വേരുകൾ സാധാരണയായി പ്രകാശത്തിൽ നിന്ന് അകന്നുപോകുന്നു (നെഗറ്റീവ് ഫോട്ടോട്രോപിസം). ജിയോട്രോപിസം: ഗുരുത്വാകർഷണത്തോടുള്ള …
Phototropism: This is the movement of a plant in response to light. It can be either positive (towards the light source) or negative (away from the light source). Gravitropism: This is the movement of a plant in response to gravity. Roots grow downward and stems grow upward, in response to the pull of gravity. Thigmotropism: …

Movement and locomotion are similar but distinct concepts. Movement is any change in the position of an object, while locomotion is the ability to move from one location to another. Movement can be intentional or unintentional, while locomotion is always intentional. Movement can involve a change of position, direction, or orientation, while locomotion is always …

The endoskeleton is a type of support system found in some animals. It is composed of rigid, hard bones or cartilage that provide a strong, supportive structure that protects internal organs and allows the animal to move. The endoskeleton also helps the animal to stay upright and to provide a point of attachment for muscles. …
Rheumatic arthritis and dislocation are two very different conditions. Rheumatic arthritis is an autoimmune condition in which the body’s own immune system mistakenly attacks the joints, resulting in inflammation, pain, and stiffness. Dislocation is an injury to the joint in which the bones of the joint become displaced from their normal positions. Treatment for rheumatic …

Synovial fluid is a viscous liquid that lubricates the cartilage and joint surface in order to reduce friction and wear. It also helps to cushion the joint and absorb shock by providing a cushion of fluid between the joint surfaces. It also helps distribute nutrients to the joint and cartilage, and helps remove metabolic waste …
