Is there sebum on plants?

NO there is no sebum on plants as plants do not excrete oil the way animals do.





What is Sebum ?





Sebaceous glands secrete an oily substance called sebum (Latin, meaning fat or tallow) that is made of fat (lipids) and the debris of dead fat-producing cells. In the glands, sebum is produced within specialized cells and is released as these cells burst; sebaceous glands are thus classified as holocrine glands.





Sebum is odorless, but its bacterial breakdown can produce odors. Sebum is the cause of some people experiencing ';oily'; hair if it is not washed for several days. Earwax is partly sebum.
