The human body is symmetrical largely due to evolutionary processes that favor balanced structures for efficient movement and function. Symmetry allows for optimal distribution of weight and forces, which enhances stability and agility. Additionally, it simplifies developmental processes, as cells and tissues can grow and organize in uniform patterns, reducing complexity in biological systems. This symmetry is a key aspect of physical appearance and can also play a role in mate selection in various species.
bilaterally symmetrical or radially symmetrical
No. There is very little, if any, symmetry in the human body. For example, even your eyes are not perfectly symmetrical.
testicles or breasts are commonly non symmetrical but in perfect situations there are no non symetricals
Cnidaria have two basic body forms: swimming Medusae and sessile Polyps, and they are both radially symmetrical.
the amoeba has no definite shape but changes due to the formation of pseudopodia
for the most part, the human body is symmetrical.
None. Even the most symmetrical face is not totally symmetrical. And since the heart, stomach, liver etc are on one side of the body, the internal organs are certainly not symmetrical.
those animals which are bilateral symmetrical are triploblastic and triploblasts are more successful and diplobalsts(radial symmetrical) due to their complex body organization
One side of its body looks different from the other.
Trees have roughly radial symmetry.
Because they are parts of phylam Annelida as I have read
Nope, there are some that are asymmetrical. Like sponges.
