Cellulose.
i think that would be the cell wall
Plant cells are surrounded by a stiff cell wall made of cellulose, which makes the cells very rigid. It is this strong structure that gives plants their sturdiness.
Well, a cell wall gives the plant cell it's straight structure, which makes the plant stand up and animals can support there own weight and plants need protection that gives the cell wall and animals dont need that protection.
The stem allows fungus to stand upward.
Well your skeletal system gives the human body structure. Without your skeleton you wouldn't be able to stand.
The cellulose molecules
Your skeleton - it also functions as an endocrine organ.
the root take in the nutrients for the plant and it take in the water from the soil. the stem only makes a plant stand and gives it shape and support plants.
Microscopes gives you a close-up picture of the cell so we can under stand the cell structure. :) -TNTSkull4
There are two system that do this. Your skeleton (bones) and your skin (integument).
the structure needed by humans to stand and move is the bone and the muscles
The Skeletonal System gives shape and form to the body and allows humans to stand, walk, and run.
