The food (sugar) made in leaves is loaded into the sieve tubes of phloem tissue
by using the energy derived from ATP
. As a result, the osmotic pressure in the tissue increases, causing the water to move into it. This process is helpful in moving the food materials according to the needs of the plant.
What is the movement of materials in phloem?
| Tissue What is moved Process | Xylem Water and minerals Transpiration stream | Phloem Sucrose and amino acids Translocation |
|---|
What is the movement of food in phloem is called?
The transport of food in plants is called
translocation
. It takes place with the help of a conducting tissue called phloem. Phloem transports glucose, amino acids and other substances from leaves to root, shoot, fruits and seeds.
What is the movement of food in a plant?
The bulk movement of substances through the conducting or vascular tissues of plants is called
translocation
.
Where is phloem located?
| Xylem Phloem | They comprise of xylem vessels, fibre and tracheids. They comprise of phloem fibres, sieve tubes, sieve cells, phloem parenchyma and companion cells. | Xylem is located in the centre of the vascular bundle, deep in the plant. Phloem is located on the outer side of the vascular bundle . |

What is the function of phloem?
The phloem tissue is the
main pathway for the long-distance transport of assimilates from source to sink organs in plants
, distributing carbohydrates produced in source tissues through photosynthesis and starch hydrolysis to sink tissues where they sustain growth and respiration or where reserve compounds are stored.
Where does the phloem take materials?
In the root, the xylem forms a central column, forming a solid support. The phloem is
towards the centre, outside the xylem
. In the stem, the transport tissues of the xylem and phloem are grouped into vascular bundles .
How do materials move through plants?
- vascular system. system of tubes (xylem/phloem) to transport materials such as water and minerals.
- xylem. carry materials from plant’s roots to the leaves.
- phloem. carry sugar away from the leaves.
- woody stem. …
- non-woody stem. …
- bark. …
- plants get energy by this. …
- this is the food source of plants.
Which kind of vascular tissue shows movement of materials in both directions?
The vascular tissue of
Phloem
shows movement of materials in multi directions.
Where is food manufactured in a plant?
Plants make food in
their leaves
. The leaves contain a pigment called chlorophyll, which colors the leaves green. Chlorophyll can make food the plant can use from carbon dioxide, water, nutrients, and energy from sunlight. This process is called photosynthesis.
How does the movement of water in a plant is differ from the movement of food in it?
Movement of food in plants is through
phloem tissue
which transport photosynthetic products from leaves to other parts of plants. Whereas movement of water takes place in xylem tissue which is from roots to leaves.
What is known as transport of food?
The transport of food from leaves to other parts of a plant is called
translocation
. The food made by the leaves is in the form of simple sugar. Phloem is present in all the parts of a plant. Phloem contains Sieve Tubes. Phloem is a long tube made of many living cells joined end to end.
What are the four types of phloem?
The four elements of phloem are
Sieve tubes, Companion cells, phloem fibers, phloem parenchyma
.
Why is xylem dead and phloem alive?
Water transport is also accomplished through physical forces and does not necessitate the use of energy. Except for phloem fibres,
all phloem components are alive
. Because food is transported by active transport, which requires energy, the majority of phloem parts are alive and not dead like Xylem.
How can you tell the difference between xylem and phloem?
| Xylem Phloem | These tissues move in a Unidirectional. (only in one direction – upward direction) These tissues move in a Bidirectional. (both ways – up and down) | Comprises | They live with hollow dead cells. They live with cytoplasm without the nucleus. | No of Tissues |
|---|
What are the two main function of phloem?
As a constitutive tissue in the plant body, phloem functions extrapolate its main function of
sugar transport
, including transport of signalizing molecules such as mRNAs, hormones, defenses from biotic and abiotic agents, sustenance of the organs, gas exchange, and storage of many ergastic materials, such as starch, …
