What is the role of cambium in dicotyledonous stems?
What is the role of cambium in dicotyledonous stems?
- It transports water and nutrients between phloem and xylem
- It helps in the production of secondary xylem and phloem tissues (correct)
- It provides structural support to the vascular bundles
- It aids in photosynthesis in the plant
Why are vascular bundles in monocotyledons referred to as closed?
Why are vascular bundles in monocotyledons referred to as closed?
- Because they lack a cambium layer for secondary tissue formation (correct)
- Due to the absence of xylem and phloem
- To prevent the loss of water through transpiration
- To protect the plant from external pathogens
In which type of vascular bundle are xylem and phloem arranged in an alternate manner?
In which type of vascular bundle are xylem and phloem arranged in an alternate manner?
- Divergent vascular bundles
- Closed vascular bundles
- Conjoint vascular bundles
- Radial vascular bundles (correct)
What distinguishes conjoint vascular bundles from radial vascular bundles?
What distinguishes conjoint vascular bundles from radial vascular bundles?

Why do vascular bundles with cambium have the potential to form secondary tissues?
Why do vascular bundles with cambium have the potential to form secondary tissues?
Vascular bundles in monocotyledons have cambium present between phloem and xylem.
Vascular bundles in monocotyledons have cambium present between phloem and xylem.
Radial arrangement of xylem and phloem is commonly found in stems and leaves.
Radial arrangement of xylem and phloem is commonly found in stems and leaves.
Conjoint vascular bundles have phloem positioned on both the inner and outer sides of xylem.
Conjoint vascular bundles have phloem positioned on both the inner and outer sides of xylem.
Closed vascular bundles are capable of forming secondary tissues.
Closed vascular bundles are capable of forming secondary tissues.
Dicotyledonous stems always have open vascular bundles due to the presence of cambium.
Dicotyledonous stems always have open vascular bundles due to the presence of cambium.
In vascular bundles with radial arrangement, xylem and phloem are situated along the same radius.
In vascular bundles with radial arrangement, xylem and phloem are situated along the same radius.
