Question

The intrafascicular cambium is a
A. Secondary meristem
B. Simple permanent tissue
C. Meristematic tissue
D. Complex permanent tissue

Answer 1

Hint:
The stems of dicots contain two types of the vascular cambium. These two types are fascicular and interfascicular cambium.Fascicular and interfascicular cambium are two types of vascular cambium tissues, which occur in the stems of dicot plants during different growth stages. The fascicular cambium is the primary meristem, later this meristem becomes the secondary meristem when the interfascicular cambium is a secondary meristem which combines with the fascicular cambium to make a continuous ring of meristematic tissue.
Furthermore, the fascicular cambium serves as the primary meristem at the beginning and becomes a secondary meristem later

Complete step by step answer:
The intrafascicular cambium is situated in the vascular bundles of dicot stems. It is present between the primary phloem and the primary xylem. Cambial rings are formed when intrafascicular and fascicular cambiums combine.They form one continuous ring. Therefore, the intrafascicular cambium is found within the vascular bundles.
The intrafascicular cambium is a primary meristem as it is derived from embryonic meristems. It is present in the plant from the start so it is primary in origin. It produces primary xylem inside and primary phloem outside. Only the secondary phloem and secondary xylem are formed during secondary growth

Option ‘C’ is correct

Additional Information:
Secondary parts of the fascicular cambium are formed from the primary parts. The interfascicular cambium and the fascicular cambium merge together forming a continuous ring of meristematic tissue.
The primary parts of the fascicular cambium are converted into the secondary parts of the fascicular cambium whereas the interfascicular cambium fuses with the fascicular cambium to form a continuous ring of meristematic tissue.

Note:
Secondary growth occurs in plants after the first season and results in an increase in the girth and thickness of the plants. It is because of the activity of the two lateral meristems the cork cambium and the vascular cambium.
