Question

Movement of food, water, etc is known as :

Answer 1

There are many substances transported across the plant body. Water, nutrients, and various other food substances are transported from one part to another. Water generally acts as a medium of transport. The movement mainly depends upon the concentration gradient.

complete answer:
-Movement of food, water is known as translocation.
-Food synthesized by the leaves are transported to the rest part of the plant by phloem. It is mainly meant for food transport.
-Water and minerals move through the xylem.
-Osmosis is the basic phenomenon by which water enters root hair.
-Upward ascend of water and minerals occur by transpiration pull.
-Sieve tubes are present in the phloem. Sieve tubes and companion cells generate enough pressure causing movement of food.
-Transport of sugar is well explained by the mass flow hypothesis.

So the correct answer is translocation.

Additional information:
-According to the mass flow hypothesis, as food gets accumulated in the cell, water goes into the cell. The rest of the process takes place as a result of the water gradient.
-The term motion refers to the change in the orientation of the body.
-The term transport also refers to movement but the bulk movement of food is translocation.
-Phloem can also transport nutrients. These get transported as a solute in a solution called phloem sap.
-Bulk transport requires energy.
-The term source is the site where food is synthesized and sink refers to the place where it must reach.
- In phloem sink generally refer to shoot, root apex, flower, fruits, and other developing seeds.

Note: Movement in phloem is bidirectional but it is along one direction in the xylem. There are no default mechanisms in plants that enable them to reach food to those parts where food cannot be synthesized.
