Xylem and phloem are the two types of transport tissue found in vascular plants. Woody stems contain both xylem and phloem.
What else can I help you with?
What is the function of the vascular cambian in the woody stems?
produces xylem and phloem
Which part of the plant contains xylem and phloem?
Xylem and phloem are typically found in the vascular tissue of plants. In stems, xylem is located towards the center while phloem is closer to the outer edge. In roots, xylem is towards the center and phloem surrounds it.
What is the growth of tissue that produces phloem and xylem in the stems of woody plants?
The growth of tissue that produces phloem and xylem in the stems of woody plants is called vascular cambium. It is a lateral meristem that produces secondary xylem (wood) towards the inside of the stem and secondary phloem towards the outside, allowing for the thickening and expansion of the stem over time.
Do xylem and phloem exist only in roots and stems?
No, xylem and phloem are present in roots, stems, and leaves of plants. Xylem transports water and minerals from roots to stems and leaves, while phloem carries sugars and other nutrients from photosynthetic tissues to other parts of the plant.
How are herbaceous and woody stems alike?
Both herbaceous and woody stems are part of the plant's structure that provide support and transportation of nutrients. They both have vascular tissues (xylem and phloem) for conducting water and nutrients. Additionally, both types of stems can produce lateral branches and leaves for photosynthesis.
Are xylem and phloem tissues?
yes, xylem and phloem are tissues in the vascular system
How is woody xylem in tilia different from xylem in the herbaceous monocots and dicots?
Herbaceous stems lack woody tissue and growth rings unlike woody xylem. Wood is a composite of cellulose fibers which require the the process of phloem in the bark to contain nutrients unlike herbaceous stems that rely on xylem that contains vessel and vascular elements.
What tissues arise from the active cell division of the vascular cambium?
The vascular cambium undergoes active cell division to produce secondary xylem (wood) towards the inside of the stem and secondary phloem towards the outside. This results in the growth of woody tissues in trees and other woody plants.
Which has scattered phloem and xylem in the stem?
Seeds that are considered monocot seeds contain phloem and xylem as scattered around. Dicot seeds have more organization, with the xylem in an x and the phloem surrounding it.
How are the inside of the soft stem and the woody stem different?
The inside of a soft stem typically contains pith, which is soft and spongy tissue, while a woody stem is composed of xylem and phloem tissues that provide structural support. Soft stems are usually herbaceous, green, and flexible, whereas woody stems are rigid, brown, and durable due to the presence of lignin.
What fibers surround the xylem and phloem tissues?
The xylem and phloem tissues in plants are typically surrounded by a layer of sclerenchyma fibers known as the vascular bundle sheath. These fibers provide structural support and protection to the conducting tissues of the plant.
What provides horizontal transport of material in stems and roots?
The vascular tissues, xylem and phloem, provide the horizontal transport of materials in stems and roots. Xylem transports water and minerals from the roots to the rest of the plant, while phloem transports sugars and other organic nutrients throughout the plant.
