Xylem transports only minerals and waters from the roots. Phloem transports food materials that are prepared by the green parts of the plants to other parts of the plant. Xylem is the dead tissues at maturity, but no cell contents. Phloem is the living tissue, but not with the nucleus.
Is xylem bigger than phloem?
Xylem tissue consists of xylem vessels, tracheids, and fibers while phloem tissue consists of sieve tubes, companion cells, phloem fibers, and parenchyma. Xylem forms the major bulk of the plant body while phloem forms the major bulk of the bark. Is Xylem Bigger than Phloem? Yes. Xylem is always larger in a plant than phloem.
What function does xylem and phloem have in common?
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.
How do vascular plants xylem differ from its phloem?
- Both they transport materials within the plant
- Both they have end walls in early stages.
- Both are made up of cells
- Both consists of highly specialized cells that are continuous from the roots through the stem to the leaves.
Does the xylem and phloem go up or down?
Unlike xylem, phloem vessels contain cytoplasm, and this goes through holes from one cell to the next. Phloem transports sucrose and amino acids up and down the plant. This is called translocation. In general, this happens between where these substances are made (the sources) and where they are used or stored (the sinks).

Which correctly describes the functions of the xylem and phloem?
Xylem transports and stores water and water-soluble nutrients in vascular plants. Phloem is responsible for transporting sugars, proteins, and other organic molecules in plants.
How do the cells of the xylem compare to the cells of the phloem?
The xylem cells have thin cell walls, whereas the phloem cells have thick cell walls.
Which best describes a xylem?
The basic function of xylem is to transport water from roots to stems and leaves, but it also transports nutrients. The word xylem is derived from the Ancient Greek word ξύλον (xylon), meaning "wood"; the best-known xylem tissue is wood, though it is found throughout a plant.
What is the difference between xylem and phloem and what is the significance of the evolution of these two structures in plants?
The two primary vascular tissues are xylem, which transports water and dissolved minerals from the roots to the leaves, and phloem, which conducts food from the leaves to all parts of the plant.
Which of the following is a difference between the transport by xylem and transport by phloem?
So, the correct answer is 'Xylem transports water and minerals absorbed by roots whereas phloem transports food prepared by leaves.
What are the differences between the transport of materials in xylem and phloem in points?
Xylem tissue helps in the transport of water and minerals. Phloem tissue helps in the transport of food. The transportation of water is from upwards roots to aerial parts of plants. Food is transported in both upward and downward directions.
Which of the following best describes the function of xylem and phloem vessels in plants?
-Phloem: transports sugars from leaves or storage tissues to other parts of the plant. -Xylem: conveys water and dissolved minerals upward from the roots to the stems and leaves.
Is xylem thicker than phloem?

Which of the following characteristics applies to both xylem and phloem transport?
These two tissues transport fluid and nutrients internally. There are also two meristems associated with vascular tissue: the vascular cambium and the cork cambium. All the vascular tissues within a particular plant together constitute the vascular tissue system of that plant.
Where are the xylem and phloem located?
The xylem is located towards the adaxial surface of the leaf, whereas, phloem is located towards the abaxial surface of the leaf.
What are the functions of xylem and phloem?
Xylem and phloem facilitate the transportation of water, minerals and food throughout the plant. Xylem carries water and minerals from the roots to...
Are xylem cells dead?
Xylem cells are made up of a long chain of dead cells known as vessel elements. The vessel elements have no organelles. The components of xylem tis...
Why are the phloem cells alive?
The cells that make up the phloem tissues need to be alive to facilitate the active transport of sucrose throughout the plant.
Which is larger, Xylem or Phloem?
Xylem fibres are smaller. Phloem fibres are larger. Found In. They are present in roots, stems and leaves. They are present in stems and leaves, which later transports and grow in roots, fruits and seeds. Movements. These tissues move in a Unidirectional. (only in one direction – upward direction)
What is the function of the Xylem?
The main activity of this tissue is to transport minerals and water from roots and carry them to other parts of the plants. It has two separate chambers, tracheids and vessels for transporting minerals and water.
Why is the phloem important?
Phloem is also important as the xylem tissues for the vascular system of plants. The main activity of this tissue is to transport nutrients and food from leaves to other growing parts of plants. The term phloem is derived from the Greek word – φλοιός (phloios), meaning bark.
What is a phloem tissue?
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. Location. It is located in the centre of the vascular bundle.
What is a dead xylem cell?
Xylem cells are made up of a long chain of dead cells known as vessel elements. The vessel elements have no organelles. The components of xylem tissues are highly lignified and scalarified. Hence, xylem cells are considered dead.
What are the elements of the tracheid?
It consists of tracheids, vessel elements, xylem parenchyma, xylem sclerenchyma and xylem fibres. It consists of four elements: companion cells, sieve tubes, bast fibres, phloem fibres, intermediary cells and the phloem parenchyma. Transports soluble mineral nutrients and water molecules from the roots to the aerial parts of the plant.
What are the features of vascular plants?
Essentially, a vascular plant has specialized features that help it to absorb water and minerals from the soil. These include special tissues such as xylem and phloem.
What is a plant specimen?
A plant specimen has seeds that are enclosed by a fruit. Which type of plant is it?
Which two transports water and nutrients in the plant?

Which cells make up ground and dermal tissue?
B. Xylem cells make up vascular tissue, and phloem cell s make up ground and dermal tissue.
What is the difference between phloem and xylem?
Xylem carries water and minerals, whereas phloem, the other type of vascular tissue, mostly carries sugar/sap. The two types of cells in xylem tissue are tracheids and vessel elements/members. Both vessel elements/members(either name is common and acceptable) and tracheids are dead at functional maturity.
What is the Xylem?
Xylem is a tissue consisting of dead, hollowed-out cells that form a system of pipes. The walls of xylem cells are lignified (strengthened with a substance called lignin ). This allows the xylem to withstand pressure changes as water moves through the plant.
What is the function of Xylem?
Xylem transports water and minerals from the roots to aerial parts of the plant. Phloem transports sugars that are synthesized in the green parts of the plant to the other parts. Xylem occupies the center of the vascular bundle. Phloem occupies outer side of the vascular bundle.
What are the two transport systems that plants use to transport food, water, and minerals?
Plants have transport systems to move food, water and minerals around. These systems use continuous tubes called xylem and phloem. Xylem carries water and minerals from the roots to the leaves while Phloem carries sugar & other organic nutrients made by plant from the leaves to the rest of the plant.
Where are the vascular bundles located in the leaf?
In leaves, the vascular bundles are located among the spongy mesophyll. The xylem is oriented toward the adaxial surface of the leaf (usually the upper side), and phloem is oriented toward the abaxial surface of the leaf.
How do plants exchange substances?
Plants could exchange substances by direct diffusion but that would be too slow so they need a transport system. Xylemtissue transports water and mineral ions, phloemtissue transports dissolved substances like sugars. Xylem and phloemare found throughout the plant (they transport materials to all parts).
