Translocation occurs within a series of cells known as the phloem pathway, or phloem transport system, with phloem being the principal food-conducting tissue in vascular plants. Nutrients are translocated in the phloem as solutes in a solution called phloem sap.
What is translocation and where does it occur?
The movement of sucrose and other substances like amino acids around a plant is called translocation . In general, this happens between where these substances are made (the sources) and where they are used or stored (the sinks): from sources in the root to sinks in the leaves in early spring time.
What is meant by translocation where it take place?
Transport of soluble product of photosynthesis or food from leaves to other parts of plants is called translocation. For translocation, food molecules enter the part of the phloem called the sieve tubes where they can be transported upwards or downwards to all parts of the plant including roots.
What is the path of translocation in plants?
Food is prepared in plant leaves during photosynthesis. It is then transported to all the parts of the plant through vascular tissues called phloem. Transport of food in phloem is bi-directional, i.e. it moves both upward and downwards.
How does the translocation of food take place in plants?
The transport of food from the leaves to the other parts of the plant occurs through the vascular tissue called phloem. As a result, the osmotic pressure in the tissue increases, causing the water to move into it. This process is helpful in moving the food materials according to the needs of the plant.
How does translocation occur?
Translocations occur when chromosomes become broken during meiosis and the resulting fragment becomes joined to another chromosome. Provided that there is no loss of genetic material, the translocation is balanced (i.e. no loss or gain of genetic material) and usually results in normal development.
What is translocation How does it take place in animals?
Translocation is the managed movement of live indigenous plants or animals (taonga) from one location to another. Translocation covers the entire process, including planning, the transfers, release, monitoring and post-release management. A translocation can have one or more transfers.
What is translocation explain?
(TRANZ-loh-KAY-shun) A genetic change in which a piece of one chromosome breaks off and attaches to another chromosome. Sometimes pieces from two different chromosomes will trade places with each other.
What is translocation of food?
In plants, food is prepared by the leaves by the process of photosynthesis. That is why; the food prepared by the leaves is transported to all the other parts of a plant through phloem. The transportation of food from the leaves to other parts of the plant is called translocation.
What are the differences between transpiration and translocation?
Transpiration is a biological process in which the water molecules are lost in the form of water vapours from the aerial parts of the plants Whereas translocation is also a biological mechanism involving the transfer of water and other soluble nutrients from one part of the plant to another through the xylem and phloem.
What is translocation in short?
Answer: Translocation is a biological mechanism involving the transfer of water and other soluble nutrients from one part of the plant to another through the xylem and phloem, which occurs in all plants.
What is the importance of translocation?
Translocation in plants occurs in the vascular tissue known as phloem. Translocation is the movement of materials from leaves to other tissue throughout the plants. Without translocation, the food prepared by the plant can’t reach other parts of the plant.
What factors affect translocation in plants?
Factors Affecting Translocation Rate The rate of photosynthesis (which is affected by light intensity, CO2 concentration, temperature, etc.) The rate of cellular respiration (this may be affected by any factor which physically stresses the plant).
What is translocation for 7th class?
Answer: The process of transporting prepared food from the leaves to other parts of the plant through phloem cells is known as translocation.
What is translocation class 10th?
Translocation is the process by which plants deliver minerals, plant growth hormones, water, and organic substance over long distances throughout the plants (from leaves to other parts).
How does translocation occur in phloem?
Sugars produced in sources, such as leaves, need to be delivered to growing parts of the plant via the phloem in a process called translocation, or movement of sugar. The photosynthates from the source are usually translocated to the nearest sink through the phloem sieve tube elements.
What is an example of translocation?
This newly formed chromosome is called the translocation chromosome. The translocation in this example is between chromosomes 14 and 21. When a baby is born with this type of translocation chromosome in addition to one normal 14 and two normal 21 chromosomes, the baby will have Down syndrome.
What are the two types of translocation?
This includes balanced and unbalanced translocation, with two main types: reciprocal-, and Robertsonian translocation. Reciprocal translocation is a chromosome abnormality caused by exchange of parts between non-homologous chromosomes. Two detached fragments of two different chromosomes are switched.
What are the three types of translocation?
1. simple translocations (one break involved) 2. reciprocal translocations (two breaks involved) 3. shift type translocations (three breaks involved) 4.
What is another name of translocation?
What is another word for translocation? move relocation transfer change changeover migration substitution switch transference transit.
What is translocation of water?
Water translocation is the transport of ions and molecules from soil (roots) to the desired location that occurs in xylem vessels as the result of the transpiration stream. 2. Transpiration is the evaporation of water from the leaves by mesophyll cells, also loss of water vapor through the stomata.
How do you use translocation in a sentence?
Another relatively rare genetic accident which can cause Down syndrome is called translocation . There is no increased risk of either mosaicism or translocation with increased maternal age. This chromosomal rearrangement is called translocation .
Which helps in translocation of food?
Phloem tissue helps in translocation of food in plants.
Is translocation an active transport?
Translocation is the movement of organic compounds from where they are made at their source, to where they are required at their sink. It is an active process which can be used to transport phloem up or down the plant.
What are the two factors responsible for Ascent of sap?
The theory states that transpiration pull or tension, cohesion property of water, and hydration of the cell walls (i.e., adhesion) are collectively responsible for the ascent of sap.
