The arrangement of vascular bundles in a monocot stem is best described as:
Arranged in a ring
Scattered
Bicollateral
Amphicribral
The arrangement of vascular bundles in a monocot stem is:
Ring-like
Scattered
Radial
Conjoint and collateral
In a monocot stem, the scattered vascular bundles are surrounded by a sclerenchymatous sheath. This sheath primarily functions to:
Store starch and other carbohydrates for the plant.
Regulate the transport of water and nutrients within the bundle.
Provide mechanical strength and support to the vascular bundles.
Facilitate gaseous exchange between the vascular tissues and the surrounding parenchyma.
Which of the following features distinguishes a monocot vascular bundle from a dicot vascular bundle in the stem?
Presence of a well-developed pith and a ring of vascular bundles
Presence of a sclerenchymatous bundle sheath and absence of cambium
Presence of a continuous vascular cylinder and presence of cambium
Presence of conjoint and open vascular bundles with a prominent pericycle
The ground tissue in a monocot stem is often described as 'undifferentiated'. This implies that:
It consists only of parenchyma cells with no other cell types.
It lacks intercellular spaces and is compactly arranged.
The cortex, endodermis, and pericycle are not clearly distinguishable.
It is incapable of further differentiation into specialized tissues.
The hypodermis in a monocot stem is typically composed of:
Parenchyma
Collenchyma
Sclerenchyma
Aerenchyma
What is the arrangement of protoxylem and metaxylem in the vascular bundles of a monocot stem?
Exarch
Endarch
Mesarch
Centrifugal
In a typical monocot stem, which tissue is immediately external to the phloem in a vascular bundle?
Xylem
Parenchyma
Sclerenchyma
Cambium
Which of the following is NOT a characteristic of a monocot stem?
Scattered vascular bundles
Presence of a well-defined pith
Absence of secondary growth
Presence of ground tissue
The vascular bundles in a monocot stem are:
Open and arranged in a ring
Closed and scattered
Open and scattered
Closed and arranged in a ring
