12 Questions
What is the role of cambium in dicotyledonous stems?
It helps in the production of secondary xylem and phloem tissues
Why are vascular bundles in monocotyledons referred to as closed?
Because they lack a cambium layer for secondary tissue formation
In which type of vascular bundle are xylem and phloem arranged in an alternate manner?
Radial vascular bundles
What distinguishes conjoint vascular bundles from radial vascular bundles?
Location of phloem only on the outer side of xylem
What determines whether a vascular bundle is classified as open or closed?
The ability to form secondary tissues
Why do vascular bundles with cambium have the potential to form secondary tissues?
Cambium facilitates the division of cells leading to growth
Vascular bundles in monocotyledons have cambium present between phloem and xylem.
False
Radial arrangement of xylem and phloem is commonly found in stems and leaves.
False
Conjoint vascular bundles have phloem positioned on both the inner and outer sides of xylem.
False
Closed vascular bundles are capable of forming secondary tissues.
False
Dicotyledonous stems always have open vascular bundles due to the presence of cambium.
True
In vascular bundles with radial arrangement, xylem and phloem are situated along the same radius.
False
Learn about the complex tissues, phloem and xylem, and how they form vascular bundles in dicotyledonous and monocotyledonous stems. Understand the role of cambium in the formation of secondary xylem and phloem tissues.
