Ploidy of generative cell
WebbOur sources of inspiration are biological cells that naturally move through body tissues, such as immune cells. These cells move by continuously changing their shape, a strategy known as ‘amoeboid movement’. Such shape changes are powered by the self-organized flows and stresses of their intracellular filaments and motor proteins.
