10 Questions
What is the primary function of xylem vessels in plants?
To transport water and minerals upwards
What is the role of companion cells in the phloem vessels?
To facilitate the movement of nutrients in the dissolved form of sap
What is the main purpose of the spiral thickening in xylem vessels?
To prevent the collapse of the vessels during transpiration
What is the main function of the sieve tube elements in the phloem vessels?
To translocate nutrients to storage organs and growing parts of the plant
What is the significance of the pits in the xylem vessels?
They allow water to move laterally between vessels
What is the role of the cambium layer in the vascular bundle?
To produce new xylem and phloem tissues
How does the arrangement of xylem and phloem in the vascular bundle differ between monocots and dicots?
Xylem is located on the inside and phloem on the outside in non-woody monocots, while the arrangement is reversed in dicots
What is the primary role of the pericycle in the stem?
To produce new xylem and phloem tissues
How does the vascular bundle arrangement in the leaf differ from the stem?
The vascular bundles in the leaf form a network, while in the stem they are arranged in a circular pattern
What is the significance of the sieve tube elements in the phloem vessels?
They allow the translocation of nutrients in the dissolved form of sap
