Detailed explanation-1: -symmetry, in biology, the repetition of the parts in an animal or plant in an orderly fashion. Specifically, symmetry refers to a correspondence of body parts, in size, shape, and relative position, on opposite sides of a dividing line or distributed around a central point or axis.
Detailed explanation-2: -In bilateral symmetry (also called plane symmetry), only one plane (called the sagittal plane) will divide an organism into roughly mirror image halves (with respect to external appearance only).
Detailed explanation-3: -When the body plan of an animal can be divided along a line that separates the animal’s body into right and left halves that are nearly identical of each other, it is said to have bilateral symmetry.
Detailed explanation-4: -Humans look symmetric on the outside but have stark asymmetries on the inside (Fig. 2.1). Thus, we have a spleen on the left but not the right. Our left lung has two lobes, but our right lung has three.
