RE-INVESTIGATION OF SECRETORY CAVITY DEVELOPMENT IN LYSIMACHIA (PRIMULACEAE)
1Department of Botany, Iowa State University, Ames, Iowa 50011, USA.
Abstract:
Nineteenth century studies described Lysimachia cavities as schizogenous, but Guttenberg (1928) reported them as only being schizogenous initially. Inner epithelial cell walls then swelled and dissolved in mucilage secreted into the cavity. Later, as a gradually solidifying resin accumulated, epithelial cells reportedly formed a new and cellulosic cell wall. My re-examination of cavity development in Lysimachia nummularia L., using a resin embedding method, revealed only typical schizogenous development, thus refuting Guttenberg's interpretation and supporting earlier workers.

Exocrine Glands: Methods of Secretion
Merocrine Secretion
Merocrine secretion is the most common type of exocrine secretion. The secretions are enclosed in vesicles and moved to the cell's apical surface, where the contents are released by exocytosis. For example, mucous, a watery secretion rich in the glycoprotein mucin, is a merocrine secretion. The eccrine...

Exocrine Glands: Types of Secretions
Serous glands produce watery secretions rich in digestive enzymes and proteins. The constituent cells of the serous gland have centrally located nuclei and eosinophilic secretory granules in the cytoplasm. The parotid gland is an example of a serous gland. It secretes saliva, which contains enzymes, such as lipases and...
Development of the Lymphatic System
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...
