What two substances does wood contain?
Wood contains Cellulose (40-50%), hemixenluloza(15-25%) and lignin(15-30%) mainly.
Plant cells store glucose as a polysaccharide called?
The cell walls of plants can actually have two layers. The primary structure is a polysaccharide known as cellulose (which is actually not digestible when consumed by humans). Later in the plant's life a second cell wall can be developed using a molecule known as lignin which is quite rigid even after the plant has died.
In a plant what substances is in the sugar?
I n a plant the substances in sugar are cellulose,sugars which is glucose.
What are crude fibres?
These are fibres that are insoluble in nature rather than diatary fibres which mostly are soluble in nature
What does cellulose mean in science?
Cellulose is a long-chain polymeric polysaccharide carbohydrate, of beta-glucose . It forms the primary structural component of green plants. The primary cell wall of green plants is made primarily of cellulose; the secondary wall contains cellulose with variable amounts of lignin. Lignin and cellulose, considered together, are termed lignocellulose, which (as wood) is argued to be one of the most common biopolymers on Earth (chrysolaminarin is often argued to be the other). Only one group of animals, the tunicates, has the ability to create and use cellulose. Some acetic acid bacteria are also known to synthesize cellulose. Cellulose is an organic compound with the formula (C6,H10,O5)n, a polysaccharide consisting of a linear chain of several hundred to over ten thousand β(1→4) linked D-glucose units. Cellulose is the structural component of the primary cell wall of green plants, many forms of algae and the oomycetes. Some species of bacteria secrete it to form biofilms. Cellulose is the most common organic compound on Earth. About 33 percent of all plant matter is cellulose (the cellulose content of cotton is 90 percent and that of wood is 50 percent). For industrial use, cellulose is mainly obtained from wood pulp and cotton. It is mainly used to produce cardboard and paper; to a smaller extent it is converted into a wide variety of derivative products such as cellophane and rayon. Converting cellulose from energy crops into biofuels such as cellulosic ethanol is under investigation as an alternative fuel source. Some animals, particularly ruminants and termites, can digest cellulose with the help of symbiotic microorganisms that live in their guts. Cellulose is not digestible by humans and is often referred to as 'dietary fiber' or 'roughage', acting as a hydrophilic bulking agent for feces.

What two substances does wood contain?
Wood contains Cellulose (40-50%), hemixenluloza(15-25%) and lignin(15-30%) mainly.
What is the main component of the cell wall of plants?
Cellulose, Hemicellulose and Lignin
What is an item that contains cellulose and lignin?
Hemp.
What are the components of wood?
Wood primarily consists of cellulose, hemicellulose, and lignin. Cellulose provides strength and rigidity, hemicellulose helps hold the cellulose fibers together, and lignin acts as a binding agent that provides resistance to decay. Additionally, wood may contain extractives, such as resins and oils, that contribute to its characteristics.
What are cellulose pectin hemicellulose and lignin?
Dietary fibers
What gives plant cell wall's their rigidity?
The cellulose molecules
What gives plants their hard feel?
Cellulose and in trees lignin.
In wood strong chains of cellulose and lignin are aligned in rows and layers are held in place by hydrogen bonds?
Yes, cellulose and lignin are two key components of wood. Cellulose provides structural strength due to its long, aligned chains, while lignin acts as a kind of 'glue' to hold the layers of cellulose together. The hydrogen bonds between cellulose molecules help reinforce the overall structure of the wood.
What does burning wood turn cellulose and lignin into?
Burning wood turns cellulose into char and carbon dioxide, while lignin is transformed into char, carbon dioxide, and some volatile organic compounds.
Why lignin and cellulose cannot decompose easily?
Lignin and cellulose are complex organic polymers with rigid structures that are difficult for most decomposers to break down. This makes them resistant to decay, especially in environments lacking the specific enzymes needed to degrade them effectively. Additionally, lignin acts as a protective barrier for cellulose, further hindering its decomposition.
Plant cell structure composed of cellulose and lignin?
