Question

Oenocytes occur in
(A) Blood
(B) Epidermis
(C) Malpighian tubes
(D) Crop

Answer 1

Oenocytes singular oenocyte, is defined as the secretory cell that is large in structure and is found in the abdominal segments of the larva of the family arthropods. It is the source of cuticularised wax in insects like cockroaches.

Complete step by step answer:
Let’s discuss the question and find the proper answer.
- Blood: Blood is defined as the body fluid from where oxygen and nutrients are transported into several parts of the body. All humans and other animals possess blood. In the vertebrates, several blood cells that are present in plasma contribute to the formation of blood.
- Epidermis: The epidermis is an outermost layer of a cell. It mainly consists of the outer epidermis and inner epidermis. The epidermis prevents skin from external factors that can affect the skin or other body parts. Through the epidermis, water is regulated that is released from the body.
- Malpighian tubes: Malpighian tubules are tubes that are slender in structure and is found in the back portion of the alimentary canal of arthropods. It consists of a cell that is single-layered and connected with the alimentary canal.
- Crop: A crop is defined as a plant product that is cultivated and grown in the maximum amount for subsistence or profit. Mainly several crops are grown by the technique of agriculture or aquaculture.
Hence option B: Epidermis is the correct answer.

Note: At the moulting time of cockroach, dermal gland secretion occurs and as a result, a cement layer is formed in the cockroach’s epicuticle. The exoskeleton of the cockroach is made up of hard sclerites that are joined by an articulate membrane. And here epidermis contains oenocytes.
