roots
Plants have these things called roots that suck up all kinds of stuff.
Roots
The special roots in plants like Rhizophora are called pneumatophores. These roots grow vertically out of the ground and help facilitate gas exchange in waterlogged environments, such as mangrove swamps, where the soil is low in oxygen. By extending above the water level, pneumatophores allow the plant to obtain oxygen for root respiration.
Plant roots take in oxygen from the air spaces in the soil through a process called diffusion. This oxygen diffuses into the roots through small openings called root hairs, allowing the roots to carry out cellular respiration and growth. Waterlogging or compacted soil can limit the availability of oxygen for roots and affect plant growth.
Not sure what answer you are looking for, but here are 4 types of roots in math. First is a square roots, next is cube roots, then the nth roots, and lastly rational roots.
Roots
All plants have roots. How else would they feed, or stand upright. http://plantandsoil.unl.edu/croptechnology2005/UserFiles/Image/siteImages/CornRootsCBLG.jpg
because they have their own special functions
Roots bring water and nutrients to the whole plant. Without water to " crack " the process of photosynthesis would not be possible. Also, roots help keep the plants upright and/or in a fixed location.
