(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 meant by translocation in Class 10?
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).
What is translocation with example?
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 is the meaning of translocation in plant?
Translocation is the movement of materials from leaves to other tissues throughout the plant. Plants produce carbohydrates (sugars) in their leaves by photosynthesis, but nonphotosynthetic parts of the plant also require carbohydrates and other organic and nonorganic materials.What is translocation class 11?
Translocation refers to “the transport over longer distances proceeding through vascular system xylem and phloem.”
What is translocation in plants class 7th?
Translocation refers to the movement of nutrients from leaves to the other tissues in the plant. … Sucrose is mainly transported in the translocation. Transpiration allows the inward movement of water in the xylem. Translocation is carried out by the phloem.
What is translocation short answer?
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 translocation in chemistry?
Translocation involves the movement of the ribosome along the mRNA in the 5′ → 3′ direction. Immediately after synthesis of the first peptide bond, the ribosomal A site contains dipeptidyl-tRNA while uncharged initiator tRNA remains in the P site.What is a translocation in geography?
Translocation describes the movement of materials upward or downward within the soil. Fine particles—particularly clays and colloids—are translocated downward, a process called eluviation.
What is an example of translocation in plants?Translocation is a biological process that involves the movement of water and other soluble nutrients through the xylem and phloem from one part of the plant to another part of the plant. For example transportation of sucrose and amino acid, up and down the plant.
Article first time published onWhat is translocation in meiosis?
Translocations. Translocations occur when chromosomes become broken during meiosis and the resulting fragment becomes joined to another chromosome. Reciprocal translocations: In a balanced reciprocal translocation (Fig. 2.3), genetic material is exchanged between two chromosomes with no apparent loss.
What is translocation in the phloem?
Phloem transports sucrose and amino acids up and down the plant. This is called translocation . In general, this happens between where these substances are made (the sources) and where they are used or stored (the sinks).
What is translocation in plants GCSE?
Translocation is the movement of sugar produced in photosynthesis to all other parts of the plant for respiration and the other processes described above. This occurs in phloem cells.
What is ascent soap?
The ascent of sap in the xylem tissue of plants is the upward movement of water and minerals from the root to the upper part of the plant body. … The conducting cells in xylem are typically non-living and include, in various groups of plants, vessel members and tracheids.
What is meant by translocation in plants by Brainly?
Translocation is defined as the transport of food and water from leaves to all the part of plant including root. ● Translocation is very essential in plants because food is synthesized in leaves only and this product is needed to be reached to all the parts of plant. ● Translocation occurs through phloem.
What is translocation Why is it essential Class 10?
Answers (1) (a) Transport of soluble product of photosynthesis from leaves to other parts of plants is called translocation. Translocation in plants takes place by vascular tissue called phloem. Translocation is essential because, without it, the food prepared by the leaves cannot reach other parts of the plant.

What is translocation in plants and through which part does it occur?
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 the parts of the plant including roots.
What is translocation and transpiration?
Translocation is the movement of water, electrolytes, or prepared food materials within a plant from one region to another. This is usually done by xylem and phloem. Transpiration is the process by which water vapor is lost to the atmosphere from living plants, mainly through the leaf surfaces.
What is transported in the xylem?
The xylem distributes water and dissolved minerals upward through the plant, from the roots to the leaves. … Phloem cells form a similar chain on the outer edges of the xylem, transporting food synthesized by the leaves downward through the stem.
Why is translocation an active process?
Translocation is a process by which glucose is transported to all the tissues of the plant body from leaves by phloem tissues. … Again when the glucose reaches the tissue it is removed from sieve tube to the tissue by active transport. For this reason translocation is considered to be an active process.
What is translocation why it is important for plants?
The transport of soluble products of photosynthesis is known as translocation. … Translocation is necessary because without it, the food prepared by the leaves cannot reach other parts of the plant. In plants, the synthesis of sugars takes place in the leaves by the process of photosynthesis.
What is translocation explain the process in steps?
Photosynthesis produces glucose in the green parts of plants, which are often leaves. This is then converted into sucrose. The sucrose is transported around the plant in phloem vessels. … The movement of sucrose and other substances like amino acids around a plant is called translocation .
What is SAP in biology?
sap, watery fluid of plants. Cell sap is a fluid found in the vacuoles (small cavities) of the living cell; it contains variable amounts of food and waste materials, inorganic salts, and nitrogenous compounds. … Phloem, or sieve-tube, sap is the fluid carrying sugar from leaves to other parts of the plant in the summer.
What is suction pull?
Suction pull may be defined as a force by which plants absorbs water and mineral from the soil. Suction pull in plants is generated by the process of transpirat. In this process, water evaporates from the surface of a leaf through microscopic pores known as STOMATA.
What is tension in plants?
Cohesion tension theory is a theory of ascent of sap. … The water molecules stick together and get pulled up by the force called tension. This force is exerted because of the evaporation at the surface of the leaf.
