# What is the name of helper that maximizes the root surface area of a plant?

Fungus .as Mycorrhizae .

### Why are animals cells circular?

Not all animal cells are circular however, the general shape and size of cells maximizes the cell's surface area to volume. This allows the cell to acquire nutrients more rapidly and (in a complex multicellular organism) maximizes the number of cells that can get that nutrition from the circulatory system.

### Do root hairs increase absorption by increasing the surface area of a root?

Simple answer: yes. It's a common theme in all aspects of the universe: the most efficient structure is that which maximizes its SURFACE AREA: VOLUME ratio. Plants and trees do this by having hairs on their roots, greatly increasing their surface area while minimally increasing volume. Side note, that's how the human intestine works too: it's full of small hairs called villi, which increase the surface area:volume ratio, therefore absorbing nutrients more efficiently.

### Why sphere has minimum surface area for given volume?

The same volume of an object, The simplest regular tetrahedron polyhedron, calculate the surface area. The surface area is pentahedral small surface area than the regular tetrahedron Regular hexahedron surface area than the surface area is small pentahedral . . . . If it is known is N-face surface area of the body, there are N +1 is smaller the surface area of the surface When N tends to infinity for a long time, Serve…
