Which observation indicates that it is a living thing that is multicellular?
a. It can be found in water.
b. It has membrane-bound organelles.
c. It possesses an uneven shape.

Answer 1

The best answer is B.

The cells of a multi cellular organisms are called eukaryotic cells and have:

1. a membrane-bound nucleus

2. numerous membrane - bound organelles including the endoplasmic reticulum, Golgi apparatus, chloroplasts and mitochondria.

3. several rod-shaped chromosomes.

Because a eukaryotic cell's nucleus is said to be surrounded by a membrane, it is said to have a true nucleus. Organelles (meaning "little organ") have specialized cellular roles just like the organs of the body have specialized roles.
