Mature phloem cells in angiosperms, specifically the sieve tube elements, lose their nuclei as they differentiate. This adaptation allows for more efficient transport of sugars and nutrients. However, companion cells, which are associated with sieve tube elements, retain their nuclei and play a crucial role in maintaining the function of the sieve tubes. Thus, while mature sieve tube elements lack nuclei, the companion cells do have them.
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.
Phloem
Phloem tissue is responsible for transporting food, such as sugars and nutrients, from the leaves and stems of a plant to other parts of the plant for growth and energy. It is part of the vascular system of a plant, along with xylem tissue which transports water and minerals.
phloem
xylem have hard wall cell. it is a dead complex permanent tissue. it is a water conducting tissue. PHLOEM; Phloem have relatively soft wall cell. it is a live complex permanent tissue. it is a water conducting tissue.
No, mature phloem tissue is not dead upon maturity. Phloem tissue remains alive and functional, aiding in the transport of sugars and other organic compounds throughout the plant. The cells in mature phloem tissue are specialized for this function and typically stay alive for an extended period.
The vascular cambium tissue makes xylem and phloem.
The food conducting tissue of a plant is called phloem. Phloem is responsible for transporting sugars and other organic nutrients produced by photosynthesis throughout the plant.
Parenchyma cells in "phloem tissue"
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.
Phloem and xylem are the two main types of vascular tissue found in plants. Xylem is the tissue that mainly carries water, and a few minerals, in the system. Phloem is the tissue that carries photosynthetic materials through the plant.
Plant tissue/ conducting tissue
No, wood is not another name for phloem tissue. Wood is made up of xylem tissue, which conducts water and minerals in plants, while phloem tissue is responsible for transporting sugars and other organic nutrients.
Phloem
Xylem tissue is responsible for transporting water and minerals from the roots to the stem and leaves of a plant. It consists of specialized cells that form a network of tubes to facilitate the upward flow of water and nutrients.
Phloem tissue is responsible for transporting food, such as sugars and nutrients, from the leaves and stems of a plant to other parts of the plant for growth and energy. It is part of the vascular system of a plant, along with xylem tissue which transports water and minerals.
The non living element of the phloem tissue is the sclereids.
