Question

Laticiferous glands occur in the plant part
A. Cortex
B. Vascular bundle
C. Epidermis
D. Endodermis

Answer 1

Hint: It is a type of elongated secretory gland which is found in the photosynthesizing plant parts. It helps in the secretion of latex and rubber which are secondary metabolites. It is of different types and helps in the secretion of various metabolites that have industrial and pharmaceutical applications.

Complete answer:
Laticiferous glands are a type of plant secretory tissue that helps in the secretion of white secretory material known as latex. This laticiferous tissue is found in the plants that are growing in the tropical deciduous forests. They are of two types; latex vessels and latex cells. Latex is an elastic compound that helps in the production of rubber. These glands are attached to the cortex. They are thin-walled parenchymatous cells that lack pits. They contain cellulose and hemicellulose that serve to secrete latex. When the laticifer contains only a single cell then, it is known as non-articulated whereas when it is formed by a row of cells then, it is known as articulated. Latex is a protoplast of the laticifer cell and most of the metabolites are stored in it.

Hence, the correct answer is option A.

Note: Laticiferous secretory glands are usually found in the younger parts of the plants and are widely distributed in almost all the tissues. It produces various compounds that function to protect plants against herbivores and penetrating pathogens. They also can seal the wounds and polymerize when they come in contact with air.
