Plants do make and use some polymers (e.g. starch, cellulose etc.), as do some animals (e.g. spider silk) but most of what we know as polymers are artificial (e.g. polyethylene, nylon etc.).
Starting materials for most polymers come from petrochemical sources such as crude oil or natural gas. These raw materials are refined and processed to extract the building blocks needed to create polymers through polymerization reactions. Additionally, some polymers can also be derived from renewable sources such as plants or animals.
from both plants and animals
The ultimate source of natural sugar based polymers are plants. Plants make sugar (glucose) by photosynthesis. The glucose is then used to make polymers such as starch (amylose and amylopectin) and cellulose. See: http://en.wikipedia.org/wiki/Polysaccharide
Monomers come together to form polymers through dehydration condensation and polymers split apart from monomers through hydrolysis.
Two polymers made by plants are cellulose and starch. Cellulose is a structural component in plant cell walls, providing strength and rigidity, while starch is a storage form of carbohydrates in plants, providing energy for growth and development.
In plants, the major polymers (carbohydrates such as cellulose and starch) are stored in the form of starch granules in specialized plant organs like roots, tubers, and seeds. In animals, the major polymers (such as glycogen) are stored in the form of glycogen granules primarily in the liver and muscles for rapid energy release when needed.
Polymers can be both depending upon which ones you are asking about. Polymer simply means "a chain of identical molecules linked together". Nonrenewable polymers would be plastics made from crude oil; renewable polymers would be cellulose and lignin in tree trunks.
No, cellulose molecules are not examples of synthetic polymers. Cellulose is a natural polymer found in the cell walls of plants and is composed of repeating glucose units. Synthetic polymers, on the other hand, are man-made polymers created through chemical processes.
Many polymers consist of a single kind of monomer that repeats over again multiple times.
Sugars in the form of polymers that our digestive system can use (starches).
Two polymers made by plants are cellulose and starch. Cellulose is a structural polymer that provides strength and rigidity to plant cell walls, while starch is a storage polymer that serves as a source of energy for plants.
The feedstock for polymers chemistry may be petroleum, methane gas, coal, plants.
