Answer

Exocrine and endocrine glands :

Exocrine glands	Endocrine glands
They secrete their products into a duct.	They are ductless glands and they secrete their products directly into blood stream.

Examples : Lacrimal glands, salivary glands, sebaceous glands.	Examples : Thyroid gland, Pituitary gland, adrenal gland.

Unicellular and multicellular glands :

Unicellular glands	Multicellular glands
They comprise of only single cell that produce secretion. They are present inbetween epithelial linings. They secrete their producrs via exocytosis.	When epithelial tissue invaginate in deep tissue it forms multicellular gland. It contains a duct at its proximal region through which the product is secreted.
