Difference between primary and secondary phloem?
Primary phloem 1. . Derived from procambium of apical meristem. 2. . District protophloem and metaphloem elements.3 Sieve tubes long and narrow. 3. Less or no development of phloem parenchyma. 4. Phloem fibres on the outer part. Secondary phloem 1. . Derived from vascular cambium. 2. . No clear demarcation between protophloems and metaphloems. 3. Sieve tubes short and wide. 4. .Well developed and abundant phloem parenchyma. 5. . Phloem fibers among the phloem parenchyma.
What does a phloem plant look like?
Xylems and phloems look alike due to their specialized structure and function. Xylem in the vascular plants consists of similar tissues of trachieds, vessels and xylem parenchyma and perform the same function of transportation of water and minerals, hence it looks similar in all such plants. Likewise phloem consists of sieve tubes, companion cells and phloem parenchyma and perform the same function of conduction of food material to different plant parts.
What is the name of the tissue that contains seive tubes?
Parenchyma cells in "phloem tissue"
What is ray parenchyma?
Ray parenchyma is a type of plant tissue that runs radially in the secondary xylem and phloem of woody plants. It is primarily responsible for storing and transporting nutrients, as well as providing structural support to the plant. These rays are often visible as radial lines in a cross-section of wood.
Example of phloem?
Phloem is a type of plant tissue responsible for transporting organic nutrients, mainly sugars, produced during photosynthesis, from the leaves to other parts of the plant, such as the roots and fruits. It consists of sieve tubes, companion cells, fibers, and parenchyma cells. One common example of phloem in plants is the phloem bundles found in vascular bundles within the stems of plants like trees.
What are the constituents of phloem?
The phloem consists mainly of sieve tubes, companion cells, phloem fibers, and parenchyma cells. Sieve tubes are responsible for transporting sugars and other organic compounds, while companion cells support sieve tube function. Phloem fibers provide structural support, and parenchyma cells store nutrients.
What is the diffference between xylem and phloem?
Xylem contains Vessels, trachieds and xylem parenchyma Phloem consists of sieve tubes, companion cells and phloem parenchyma

How do phloem differ from xylem?
Both are different structurally and functionally. The xylem cosists of Vessels, trachieds, and parenchyma and is responsible for conduction of water and minerals. the phloem consists of sieve tubes, companion cells and phloem parenchyma and is responsible for conductions of prepared food material in different parts of the plant.

What type of tissue surrounds the chloroplasts and the xylem and phloem in the leaves?
The chloroplasts in leaves are surrounded by a double membrane called the chloroplast envelope. Xylem and phloem in leaves are surrounded by a layer of parenchyma cells, which provide support and protection to these vascular tissues.
What are the tissues of plant?
There are four types of plant tissue. Vascular tissue , which is xylem and phloem, and epidermal tissue which is comprised of parenchyma cells. The ground tissue is a combination of parenchyma, collenchyma, and sclerenchyma cells. And the meristematic tissue is made of parenchyma cells.
Why are tissues present in plants?
Many types of tissues are present in plants such as - Parenchyma, sclerenchyma, chlorenchyma, collenchyma, aerenchyma and complex tissues like xylem and phloem to perform specialized functions. Such as chlorenchya in photosynthesis, sclerenchyma and collenchyma to provide strength and regidity, parenchyma for storage and xylem and phloem for conduction etc.
What are the functions of parenchyma tissue?
The basic function of the parenchyma tissue is to facilitate the transport of the small molecules between them.
How is pholem different from xylem?
Xylem is different from phloem structurally and functionally.Xylem consists of Tracheids, vessels and xylem parenchyma whereas phloem consists of Sieve tubes, companion cells and phloem parenchyma.Xylem conducts water and minerals to the leaves whereas phloem transports the prepared food from leaves to different parts of plant body.
