What is a elongated cell?
The term elongation will be used for any permanent enlargement of cells already formed by differentiation. As the size of a plant cell is determined by the extent of the surface of its wall, cell elongation may be defined also as any permanent increase in the surface of the cell wall.
What is the meaning of elongated in biology?
In general, the term elongation refers to the state, act, or process of lengthening. In biology, the term often denotes to a biological process where a biological entity is lengthened.
Which cells are elongated in shape?
Nerve cells and smooth muscle cells are elongated one.
What does elongation mean?
1 : the state of being elongated or lengthened also : the process of growing or increasing in length chain elongation in DNA synthesis the elongation of a muscle under tension. 2 : something that is elongated.
Why do cells elongate?
Cell elongation is an important process for plant growth, especially in plant shoots. The cell wall helps to counteract osmotic pressure created by diffusion of water across the plant’s cell membrane; it also, however, can restrict cell growth.
What is stimulate cell elongation?
Cell elongation, emission of filopods, and concomitant cell mobility, as triggered by beta-ecdysone, imply the assembly of microtubules and microfilaments, which suggests that the synthesis of the main cytoskeletal proteins, namely actins and tubulins, is induced by the hormone.
What does elongated mean in medical terms?
1. the act or process of increasing in length. 2. a radiographic distortion in which the image is longer than what is being x-rayed.
What does elongated shape mean?
If something is elongated, it is very long and thin, often in an unnatural way. adj.
Which cells is elongated and branched?
- Nerve Cells are long and branched because they need to make contact with other nerve cells and carry signals over long distances (from brain to other parts of the body)
- Muscle cells are spindle shaped because muscles contract and relax. So, spindle shape makes it easier to contract and relax.
What is the difference between cell elongation and cell division?
Cell differentiation is when a cell becomes specialized to perform a specific function (eg it becomes a nerve cell). Most cell differentiation occurs in the embryonic stage; some still occurs in the adult stage. Cell elongation is when the cell elongates and becomes larger. This occurs in the root of plants.
What is elongation in tensile test?
Elongation is measured by applying tensile force, or stretching the material in the same manner as described previously, and determining the change in length from original. Elongation is expressed as a percentage of the original length. Ultimate elongation is the percentage change in length from original to rupture.
How do you determine elongation?
Elongation is calculated by dividing the distance travelled by the original gauge length.
