What is translocation of assimilates in plants?
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.
In which form food is translocated in plants?
Food is synthesized in plants in the form of hexose sugars, like glucose and fructose. Fruits are specially rich in fructose. Hence, fructose is also called as fruit sugar. Sugars are transported in the form of disaccharide sugar sucrose.
What is translocation in plants meaning?
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 are assimilates in plants?
In the process of photosynthesis, carbon dioxide (CO2) and water (H2O) are trans-formed into sugars or assimilates, with the help of energy from sunlight. These sugars can be used as building blocks for plant tissue production and to make new cells, for instance.
Where does translocation of assimilates take place describe?
The place where these assimilates are produced is called the source, and the place they are moved to is called the sink. Translocation occurs in the phloem tissues, which consist of tube-like vessels called phloem vessels.
What is translocated in which form?
The movement of organic food in soluble form from one organ to another organ is called translocation of food. This translocation always occurs from high concentration to low concentration. The prepared food in the form glucose stored as starch, is always converted to soluble sucrose form for translocation.

What is the meaning of translocation in biology?
Listen to pronunciation. (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.
Which materials are translocated in the phloem?
Nutrients are translocated in the phloem as solutes in a solution called phloem sap. The predominant nutrients translocated are sugars, amino acids, and minerals, with sugar being the most concentrated solute in the phloem sap.
How are assimilates loaded in phloem?
Assimilates move through the spaces in the loose cellulose fibres of the cell wall, known as the apoplast. They move into the phloem by diffusion. Active transport is used to maintain a concentration gradient.
Which of the following is translocated through phloem?
Solution. Hormones, amino acids and sugars are transported or translocated through phloem.
How are assimilates loaded into phloem?
In what form the prepared food is translocated by the phloem?
sucrose solution
Solution : Transport of food in plants The food prepared in the green leaves of plants is transported through phloem in the form of sucrose solution to storage organs of roots, seeds and fruits. This process is called translocation.
In which form does translocation of sugar take place in flowering plant?
sucrose
Flowering plants produces sugar in the form of glucose but translocate in the form of sucrose because sucrose is more energy efficient in storage and transferring, less reactive than glucose and water soluble.
How is organic food translocated in plants?
Food materials are manufactured mainly in the leaves and are translocated to the other regions of the plant through the phloem. Some of this is utilized for the growth of the plant, while the excess is stored. Whenever needed, the stored food material is drawn to the regions of necessity again through the phloem.
Which of the following elements is necessary for translocation of sugars in plants?
Boron
Boron is an essential micronutrient for plants. It is required for transportation of sugars.
What are the two types of translocations?
There are two main types of translocations: reciprocal and Robertsonian.
What is phloem translocation?
Phloem (/ˈfloʊ. əm/, FLOH-əm) is the living tissue in vascular plants that transports the soluble organic compounds made during photosynthesis and known as photosynthates, in particular the sugar sucrose, to the rest of the plant. This transport process is called translocation.
How is the food translocated in the phloem?
Phloem is comprised of cells called sieve-tube elements. Phloem sap travels through perforations called sieve tube plates. Neighboring companion cells carry out metabolic functions for the sieve-tube elements and provide them with energy.
What are the factors affecting translocation of assimilates in plants?
Competition among various sink tissues or organs such as young leaves, stems, roots, fruits and seeds for transport sugars is an important factor in determining translocation pattern in whole plant. Experiments have shown that if a sink is removed from a plant, there is increased translocation of assimilates to other competing sinks.
What is plant translocation?
Plant translocation refers to the transfer of substances within different parts of a plant. Explore the definition and mechanism of plant translocation and discover material movement and transport tubes. Updated: 01/10/2022 When you eat, how does the food get where it needs to go?
What happens to assimilate after it is produced?
Once produced, assimilate is transported to many areas in the plant. It can be transformed into many compounds, some of the structural compounds, such as cellulose and hemicellulose that provide for the physical structure of the plant and usually remain where they are synthesized.
What is the mass flow hypothesis of translocation?
The entire process of movement of materials via pressure is known as the mass flow hypothesis. This hypothesis is one of the most widely accepted as far as methods of translocation in plants. Let’s review. Translocation is the movement of materials in plants from the leaves to other parts of the plant.
