Question

In stems of conifers and angiospetms true endodermis is lacking.Why?​

Answer 1

Answer:

In many conifers and angiosperms undergoing secondary growth, endodermis with casparian strip is only developed in roots. The endodermis is present between the cortex and the stele. In these conifers and angiosperms endodermis is discarded along with cortex during the development of periderm from pericycle. As the result of growth endodermis is pressed with the radial expansion of vascular cylinder due to anticlinal divisions. Endodermis can prevent the water and other soluble substances to pass through the apoplastic pathway.

Answer 2

Answer:

Explanation:

"In stems of conifers and angiosperms endodermis is lacking as the endosperms present in the cotyledons are present while the growing age of the plant, it gets consumes most of the time.

This is the cause why most of the time is it absent but in some of the few cases it is present in the conifers and angiosperm is lacking but it is a possibility that there can be some time presence of it.
