What is translocation in biology 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).

Where is translocation in biology?

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 an example of a 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 is translocation and its types?

There are two types of translocations, reciprocal and Robertsonian. Reciprocal translocation is the exchange of genetic material between homologous chromosomes. Robertsonian translocation refers to those that involve the fusion of two acrocentric chromosomes at their ends.

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 very short answer?

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 are the functions of translocation?

Translocation is the process within plants that functions to deliver nutrients and other molecules over long distances throughout the organism.

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 explain the process in steps?

(1) The transportation of food from the leaves to other parts of the plant occurs in the vascular tissue, namely the phloem. This process of transporting food is known as translocation. The phloem consists of companion cells, sieve tubes, phloem parenchyma and fibres.

Why is translocation important in plants?

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 causes translocation of chromosomes?

Translocations generally result from swapping of chromosomal arms between heterologous chromosomes and hence are reciprocal in nature (Figure 1) (8,9). DNA double-strand breaks (DSBs) are prerequisites for such translocations, although little is known about their generation.

What is difference between translocation and crossing over?

It involves the exchange between two homologous chromosomes. Translocation can create chromosomal abnormalities. Crossing over is a general process that happens during meiosis (prophase Ⅰ). It is a type of mutation which alters genetic information.

Is translocation active or passive?

Since energy is involved, translocation through phloem is an active process, unlike diffusion which is passive and does not require the expense of energy.

What is translocation and transpiration?

*Transpiration is the evaporation of water from the leaves in the form of water vapour whereas translocation is the transportation of synthesized products (sugars)in a plant. *Transpiration always occurs against the gravity while translocation does not always occur against gravity.

What is translocation Toppr?

Translocation is the transfer of one part of a chromosome to another part of the same or a different chromosome, resulting in rearrangement of the genes.

What is translocation Class 10 SSC?

Solution. The movement of the ribosome from one end of the mRNA to the other end by the distance of one triplet codon during translation is known as translocation.

What is mean by translation and translocation?

Translation is the process of formation of protein from RNA. Translocation is the movement of materials in plants from the leaves to other parts of the plant.

What is translocation Where does it take place Class 7?

Solution : Transport of soluble product of photosynthesis ot 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 translocation in Brainly?

Expert-verified answer Translocation is a biological process that occurs in all plants and involves the movement of water and other soluble nutrients through the xylem and phloem from one part of the plant to another. o2z1qpv and 794 more users found this answer helpful.

What cells are involved in translocation?

The process of translocation takes place in the phloem cells. Thus the cell involved would be companion cells, sieve elements & parenchymatous tissue.

What transports xylem?

The xylem distributes water and dissolved minerals upward through the plant, from the roots to the leaves. The phloem carries food downward from the leaves to the roots. Xylem cells constitute the major part of a mature woody stem or root.

What is translocation of food in plants?

In the case of plants, a term called translocation is used to describe the process of transportation of food to various parts of the plants from the leaves.

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 translocate a word?

verb (used with object), trans·lo·cat·ed, trans·lo·cat·ing. to move or transfer from one place to another; cause to change location; displace; dislocate.

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.
