In monocot roots which types of vascular bundles are found?
Collateral, conjoint and closed
Radial with exarch xylem
Bicollateral, conjoint and closed
Radial with endarch xylem
B.
Radial with exarch xylem
When xylem and phloem groups are located on different radii, the bundles are said to be radial e.g. root. The protoxylem element lie at the periphery and metaxylem in the centre, this condition is called exarch e.g. root.
In bacteria respiration occurs in
cytoplasmic membrane
mitochondria
nuclear membrane
endoplasmic reticulum
