In our lives, many things have a certain form and shape that help with their function (ex. the nozzle of a spray bottle).
1. Choose anything (does not have to be related to the body) and discuss that relationship. Then think about your cells – they too have certain forms that help with function. Discuss this relationship.

I will take as an example the drippers with a curved tip. And for the case of the cells of the human body I will take the sperm.

Explanation:

Curved tip drippers differ from those with a straight tip in that thanks to their curved shape, the liquid spill is slower.

In the case of sperm, its main function is to carry the father's DNA to the ovule, which is inside the female reproductive system. To get there, the sperm has to leave the male reproductive system, enter the female reproductive system and overcome some barriers. To achieve this, the sperm has a shape similar to an arrow: a head, which carries the paternal DNA and a tail, which allows it to move quickly and more or less straight and also an intermediate piece, which joins them and gives elasticity to the cell so that it can move easily.
