Xylem tissues are the tubular-shaped structure, with the absence of cross walls. This tissue
resembles the shape of a star
. Phloem tissues are tubular-shaped, elongated, structures with the presence of walls with thin sieve tubes. It is located in the centre of the vascular bundle.
What are the differences between xylem and phloem?
| 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 are similarities between xylem and phloem?
The
cell wall is made up
of cellulose of both xylem and phloem. Both contain chloroplast. Both contain vascular tissue, which helps in transportation of material throughout the plant. Both xylem and phloem contain parenchymatous cells.
What is the difference between xylem and phloem Brainly?
Answer: Xylem and phloem
facilitate the transportation of water, minerals and food throughout the plant
. Xylem carries water and minerals from the roots to the leaves. Whereas, phloem carries the food prepared by the leaves to different parts of the plant.
What is common in xylem and phloem tissue?
Therefore, the common component in both xylem and phloem is
parenchyma
. Parenchyma tissue is made up of thin-walled parenchyma cells. They are also called photosynthetic tissue as they have chloroplast and hence, take part in photosynthesis. Parenchyma is a living cell, and has a prominent nucleus.
What are the components of xylem?
The structural elements of xylem are
tracheids, vessels or tracheae, xylem fibres, xylem parenchyma and rays
. The tracheid is derived from a single cell and can be regarded as the basic cell type of xylem tissue.
What happens if phloem tissue is absent?
If phloem is absent,
plant will die because
the plants cells will not get energy to function properly. Phloem is the vascular tissue responsible for the transport of sugars from source tissues (ex. photosynthetic leaf cells) to sink tissues (ex. non-photosynthetic root cells or developing flowers).
What is the main function of xylem?
Xylem is the specialised tissue of vascular plants that
transports water and nutrients from the plant–soil interface to stems and leaves
, and provides mechanical support and storage. The water-conducting function of xylem is one of the major distinguishing features of vascular plants.
What is the structure and function of xylem and phloem?
Xylem tissue transports water and nutrients from the roots to different parts of the plant
, and also plays a role in structural support in the stem. Phloem tissue transports organic compounds from the site of photosynthesis to other parts of the plant.
What is xylem and phloem and its function?
Xylem transports water and minerals from root to the whole body of the plant
. Its basic function is to move water from roots to leaves and shoots. Phloem transports food materials to the whole plant body. Its basic function is transport of food from source tissues.
What is in the phloem?
Phloem, also called bast, tissues in plants that conduct foods made in the leaves to all other parts of the plant. Phloem is composed of
various specialized cells called sieve tubes, companion cells, phloem fibres, and phloem parenchyma cells
. … The other cell types in the phloem may be converted to fibres.
What is the difference between xylem and xylem vessels?
The xylem tissue
moves water and nutrients
to various parts of the plant such as shoots and leaves. Its major components include xylem parenchyma, xylem fibers, tracheids, and xylem vessels. The xylem vessel is one of the two cell types of tracheary elements, the other is the tracheid.
What is the role of transpiration in transportation?
Transportation in plants | Long Answer Questions (LA)
Transpiration results in transpiration pull which thereby increases the rate of absorption of water along with minerals from the soil through roots. Transpiration
helps in transportation of absorbed minerals to all the parts of the plant
.
What are 2 similarities and 2 differences between transport in xylem and phloem?
| Xylem Phloem | Movements | 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. |

What are examples of xylem and phloem?
Xylem and phloem are examples of
Complex tissue or Vascular tissues
. Note: Photosynthesis in leaves necessitates a large amount of water from the xylem and generates a large amount of sugar for the phloem.
What are xylem and phloem together called?
Hint: Xylem and phloem are collectively known as
vascular bundles
. Xylem transport water and minerals from the roots to the entire plant body while phloem has the responsibility to transport the organic food inside the body of the plant. Complete answer: Xylem and phloem are an example of complex permanent tissues.
