How do hyphae spread from one area to another?
a. they use flagella to move through liquid.
b. they extend pseudopods like walking feet.
c. they use their cilia to slide along rocks.
d. they grow quickly underground.

D. They grow quickly underground.

A hyphae is a long, branching filamentous structure found in fungus species. A hyphae is a part of vegetative growth and a group of hyphae is called as a mycelium. Fungi are saprophytic organisms that means they are dependent upon other organisms such as plants and animals for their food and energy requirements. The fungal hyphae spreads grow quickly underground in order to search decaying and dead remains over which these fungus can feed upon.

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
