What is the function of secretory tissue?
On the basis of the variability and location of the secretory tissues in the plant body, the following are suggested: (1) In relation to their surrounding environment, the secretory tissues fulfill two very important ecological functions—protection against herbivores and pathogens and attraction of pollinators.
What are internal secretory tissues?
Internal Secretory Structures of Plant Tissues: The internal secretory structures may be composed of a single cell or of groups of cells. They may occur throughout a tissue (e.g., oils or enzymes) or may be localised in distribution.
Where are secretory cells?
More. Cells which are specialized to secrete mucus are called mucous cells. Examples in the GI system include secretory cells of the salivary glands, esophageal glands, stomach surface, pyloric glands, and Brunner’s glands of the duodenum. These cells are typically organized into tubular secretory units.
What are secretory materials in plants?
The secretory materials are those ergastic matters which do not serve as food, and so are not directly concerned with the nutrition and growth of the plants. The three common secretory materials are: (1) Colouring Matters (2) Enzymes and (3) Nectar.
What are the types of secretory tissue?
The tissues that are concefjbhknksecretion of gums, resins, volatile oils, nectar latex, and other substances in plants are called secretory tissues. These tissues are classified as either laticiferous tissues or glandular tissues.
What are the types of secretory cells?
Summary: The intestinal epithelium consists of four main specialized cell lineages: absorptive enterocytes and three secretory cell types known as enteroendocrine, Paneth, and goblet cells.
What are the two types of secretory cells?
The two main types of exocrine secretory cells of the stomach are parietal cells and chief cells. Parietal cells secrete hydrochloric acid and chief cells secrete digestive enzymes such as pepsin.
What is the meaning of secretory?
: of, relating to, or promoting secretion also : produced by secretion.
What is an example of secretion?
A secretion is a substance made and released by a living thing, like when your skin sweats. For example, the secretions of some frogs are a type of poison. Some secretions stay within an animal, like the bile secreted by our livers. Saliva is another secretion.

What are the 4 types of glands?
There are four types of glands in the integumentary system: sudoriferous (sweat) glands, sebaceous glands, ceruminous glands, and mammary glands. These are all exocrine glands, secreting materials outside the cells and body.
Which is the largest gland in the human body?
The liver
What are the three types of gland?
Types of Glands
- Salivary glands – secrete saliva.
- Sweat glands- secrete sweat.
- Mammary glands- secrete milk.
- Endocrine glands – secrete hormones.
What is the most common type of secretion?
A cell is classified as merocrine if the secretions of that cell are excreted via exocytosis from secretory cells into an epithelial-walled duct or ducts and then onto a bodily surface or into the lumen. Merocrine is the most common manner of secretion.
What are the two main types of glands?
Glands are important organs located throughout the body. They produce and release substances that perform certain functions. Though you have many glands throughout your body, they fall into two types: endocrine and exocrine.
What is gland tissue?
Glandular epithelium, also known as glandular tissue, refers to a type of epithelial tissue involved in the production and release of different secretory products, such as sweat, saliva, breast milk, digestive enzymes, and hormones, among many other substances.
