What is translocation in phloem?

What is translocation in phloem?

Translocation in phloem mainly refers to the transportation of food, nutrients and other essential substances from leaves to other parts of the plant.

What is translocation in xylem and phloem?

Phloem consists of living cells arranged end to end. Unlike xylem, phloem vessels contain cytoplasm, and this goes through holes from one cell to the next. Phloem transports sucrose and amino acids up and down the plant. This is called translocation .

What is called translocation?

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 function of translocation?

Its function is the transportation of food and nutrients such as sugar from leaves to other parts of the plant. This movement of substances is called translocation.

What is translocation in plant?

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 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 xylem translocation?

Translocation in vascular plants means the movement of organic molecules and some mineral ions. Movement of water from the soil to the leaves occurs in xylem vessels as the result of Transpiration.

Is translocation a function of phloem?

Phloem is an elongated, tubular shape with thin-walled sieve tubes vascular tissue. Its function is the transportation of food and nutrients such as sugar from leaves to other parts of the plant. This movement of substances is called translocation.

What is translocation 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 translocation Byjus?

The products of metabolic processes, particularly photosynthesis, are moved from leaves, where they are formed, to other parts of the plant. This transport of soluble products of photosynthesis is called translocation and it occurs in the part of the vascular tissue known as phloem.

What is assimilation and translocation?

The products of photosynthesis (mainly the sugar sucrose) are a major component of the substance found in the phloem, called assimilate. Ions, amino acids, certain hormones, and other molecules are also found in assimilate. The movement of assimilate is called translocation, or assimilate transport.

What is translocation in biology?

(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 according to class 10?

How does translocation occur?

Translocations generate novel chromosomes. In a translocation, a segment from one chromosome is transferred to a nonhomologous chromosome or to a new site on the same chromosome. Translocations place genes in new linkage relationships and generate chromosomes without normal pairing partners.

What is translocation and its type?

The term translocation is used when the location of specific chromosome material changes. There are two main types of translocations: reciprocal and Robertsonian. In a reciprocal translocation, two different chromosomes have exchanged segments with each other.

What is translocation Why?

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. The translocation of food (carbohydrates) occurs in the sieve tubes with the help of companion cells.
