The form of a person or thing is its shape. To conform is to fit in with others in form, shape, or manner. Something formal, such as dinner, follows a specific custom or form. The format of something, such as a book, is its general shape and arrangement.
Amoeboid movement is the most common mode of locomotion in Eukaryotic cells. It is a crawling-like type of movement accomplished by protrusion of cytoplasm of the cell involving the formation of pseudopodia. The cytoplasm slides and forms a pseudopodium in front to move the cell forward. This type of movement has been linked to changes in action potential; the exact mechanism is still unknown.
Amoebae: Protists Which Move and Feed Using Pseudopodia. The amoeboid body form is one of the most widespread. Not only does it occur in amoebae, but it is also found in algae, fungi and animals. From comparisons of molecular data and from life history data, it is clear that the amoeboid body form is an adaptive form and that the amoebae are polyphyletic.
