The structure and shape of each type of human cell depends on what function it will perform in the body. For example, red blood cells (RBCs) are very small, flat discs, which allows them to easily fit through narrow capillaries and around sharp corners in the circulatory system to deliver oxygen throughout the body.
The elongated shape of muscle cells allows the contraction proteins to line up in an overlapping pattern that makes muscle flexing possible.
And human sperm cells’ structures allow them to “swim” long distances to reach an egg for fertilization
Do you see the tectonic plates are moving away from each other
B. bacteria has a negative image in our world.... people forget that there is good bacteria in the body that helps break down callulose in some animals' digestive system and helps to fight infectious diseases
