Question

What defines a collection of cells as a gland rather than an organ?

Organs consume more energy.

Glands vary by gender; organs do not.

Glands export products to other body parts.

Organs operate autonomously; glands do not.

Answer 1

The defining characteristic that differentiates a collection of cells as a gland rather than an organ is that glands export products to other body parts. Glands are specialized structures that produce and secrete substances such as hormones, enzymes, and sweat. Organs, on the other hand, are structures composed of multiple types of tissues that perform specific functions within the body.
