The upward conduction of water from roots is carried out by
The correct option is B Xylem
The correct option is option B.
Explanation of the correct option:
- The complex tissue of plants that helps in the conduction of water and minerals from roots to other parts of plants is called the xylem.
- It provides mechanical support to plant parts
- In flowering plants, the Xylem is composed of four different elements namely tracheids, xylem vessels, xylem fibers, and xylem parenchyma.
- In gymnosperms, xylem vessels are not present.
- Xylem tracheids are the elongated, tube-like cells with thick lignified walls that are the main conducting tissue
- Xylem vessel is a long cylindrical tube-like structure with lignified walls, is the main water-conducting tissue.
- Xylem fibers are cells with thick walls and xylem parenchyma are living thin-walled cells that help in storing food in form of starch or fat.
- Xylem vessels and tracheids transport water to different parts of plants by diffusion.
Explanation of the incorrect options:
Option A:
Bark refers to all the tissue types (Phellogen, phellum, phelloderm, and secondary phloem) exterior to the vascular cambium.
Option C:
The complex tissue of plants that helps in the conduction of food from leaves to other parts of plants is called phloem.
Option D:
Vascular cambium is the meristematic layer that separates xylem and phloem, in the young stem, it is single-layered but becomes multi-layered and cuts off into mature secondary xylem towards the pith and secondary phloem towards the periphery.
Final Answer: the upward conduction of water from roots is carried out by xylem.
