Text Solution

Verified by Experts

The correct Answer is:
A
Sieve tubes are components of phloem, It is devoid of nucleus at maturity and its metabolic activities are controlled by nucleus of companion cells. Albuminous cells are not produced by angiosperms. They are present in gymnosperms only. In dicot roots, the vascular cambium formed during secondary growth. Primary meristem contributes to the formation of primary plant body.
