Mitosis is the process of eukaryotic cell division where the cell nucleus splits into two identical daughter nuclei. It is followed by the division of the cytoplasm and the organelles, resulting in two daughter cells. Mitosis is a continuous process, which is divided into four stages: prophase, prometaphase, metaphase, anaphase, and telophase. During prophase, the …

Cell plate formation is a process of cell division in plant cells, which involves the formation of a new cell wall in the middle of two daughter cells. It begins when the cell membrane at the equator of the dividing cell pinches inwards, forming a vesicle known as the preprophase band. The preprophase band then …
Cytokinesis is the process in which a single cell divides into two daughter cells. It is the final stage of mitosis, the process by which replicated chromosomes are separated into two new cells. During cytokinesis, the cytoplasm of a single cell divides into two new daughter cells, a process that is necessary to maintain the …
The chromatin reticulum undergoes several changes during the process of transcription. When a gene is turned on, the chromatin fibers become less tightly wound, allowing for the transcription machinery to access the gene. During transcription, the chromatin fibers become even more unwound, allowing the transcription factors and RNA polymerase to interact with the DNA. Once …
Karyokinesis is the process of cellular division that results in the formation of two daughter cells. This process involves the duplication and distribution of genetic material, which is accomplished through mitosis and meiosis. Karyokinesis can refer to either mitosis or meiosis, depending on the context.
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 …
