What is the primary function of the phloem in vascular plants?
The primary function of the phloem in vascular plants is to transport sugars, organic molecules, and nutrients produced by photosynthesis in the leaves to other parts of the plant, such as roots, stems, and fruits. This transport system is bidirectional and helps in maintaining the growth and metabolic functions of the plant.
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 is closest to the center of a woody stem?
Vascular cambium
What is the function of phloem fibers?
Phloem fibers provide structural support to the phloem tissue, helping it maintain its integrity and function in transporting sugars, hormones, and other nutrients throughout the plant. They also aid in defense mechanisms against pathogens and mechanical stress.
The vascular system of a three-year-old eudicot stem consists of?
3 rings of xylem and 1 of phloem
What is the vascular bundle of stems made up of?
They are made up of xylem and phloem. The xylem's primary function is to transport water, while the phloem transports nutrients.
Is wood from a tree secondary or primary phloem?
Wood is primarily composed of secondary xylem, while phloem is the vascular tissue responsible for transporting nutrients. Trees produce primary phloem during their early growth stages, but as they mature, they develop secondary phloem through the activity of the vascular cambium. Therefore, while wood itself is not phloem, trees have both primary and secondary phloem for nutrient transport.
Where is the location of cambium in plant?
The cambium is a layer of actively dividing cells located between the xylem and phloem in vascular plants, mainly in the stems and roots. Its primary function is to produce new cells for secondary growth, resulting in the thickening of the plant body.
Function of xylem and phloem?
the xylem transports water and the phloem transports organic substances.

What is the function of the phloem in a leaf?
Phloem provides a passage for the downward movement of the food manufactured in leaves to various parts of the plant.
What is the function of xylem and phloem in plants?
they r bothe tisues
What is closest to the center of a woody stem?
Vascular cambium
Why is the difference between xylem and phloem important in a plant?
There is structural difference between xylem and phloem. This is because their function is also different. Had there been no difference in structure, how these could have performed different function?
What is the function of the vascular cambian in the woody stems?
produces xylem and phloem
Is phloem dead or alive?
Phloem is a living tissue in plants, responsible for transporting nutrients, particularly sugars produced through photosynthesis, from leaves to other parts of the plant. The primary components of phloem, such as sieve elements and companion cells, are alive at maturity, allowing for the active transport of substances. However, the sieve tube elements lose their nucleus and most organelles as they mature, but they still function as living cells.
