Plants use carbohydrates to build things such as cellulose. How do plants acquire these building blocks to build mass?
AlekseyPX

Answer:

Photosynthetic process

Explanation:

Cellulose, a tough, fibrous and water-insoluble polysaccharide in the cell walls of plants. It is the most abundant organic macromolecule on Earth and also the main component of a plants structure, conferring rigidity on the plants' cells.

Cellulose chains are arranged in microfibrils or bundles of polysaccharides arranged in fibrils which in turn make up the plant cell wall.

All plants are made up of polysaccharides, a very large sugar molecule made of hundreds or thousands of single sugar units (monosaccharide). Cellulose is composed of a long chain of at least 500 glucose molecules joined together by B-1,4- linkages.

Green plants create this simple sugar molecules (glucose) on their own through the process of photosynthesis. Photosynthesis is the chemical combination or fixation of C02 and water by the utilization of energy from the absorption of visible light. This glucose produced is a building carbohydrate that combines with other sugars to form the plant structure (as they make up part of cellulose) and store energy.

Higher on the outside,

because the potatoes feel heavier, that means they must contain more water, which also means they had to have sucked in some water or had more water in them to begin with.

concentration usually likes to go from high to low in order to balance things out, so the only way water could enter the cells through osmosis would be if the concentration of water were higher on the outside of the cells
