Dehydration and Clearing in Histopathology

In histology and histopathology, dehydration is a crucial step in the preparation of tissue specimens for microscopic examination. Dehydration is the process of removing water from the tissue by using a series of graded alcohols before embedding it in a medium that can be sliced thinly for microscopic examination. The purpose of dehydration is to […]

Anomalous Secondary Growth in Beetroot Storage Roots

In many dicots, the root functions as a storage region. The secondary growth in these storage roots is usually anomalous type. Example: Secondary thickening in Beta vulgaris (Beetroot – Chenopodiaceae) and Secondary thickening in Ipomoea batatas (Sweet potato – Convolvulaceae) The present post discusses the Anomalous Secondary Growth in Beetroot storage roots (Beta vulgaris). Anomalous […]
