Explanation:
Cellulose, hemicellulose and lignin form structures called microfibrils, which are organized into macrofibrils that mediate structural stability in the plant cell wall.
The most important biological role of hemicelluloses is their contribution to strengthening the cell wall by interaction with cellulose and, in some walls, with lignin.
Mainly by nitrogen-fixing bacteria in the soil and oceans
Answer:
Autotroph is an organism that produces complex compound on itself and heterotrophs are the one which cannot produce its own food.
Explanation:
- Autotroph are the primary producer that can create the complex compound required for their development from the simple substances that are easily found in the environment.
- Autotroph uses energy from the inorganic chemical reactions and light.
- Heterotrophs depend upon the other nutrition sources because they cannot produce on their own.
- Heterotrophs are consumer where as autotrophs are producer in teh ecosystem.

Answer:
they are comer than their surroundings.
Sunspots are cooler because their magnetic fields inhibit the replenishing of heat from convective flows (due to the interaction between plasma and magnetic fields). This allows them to cool radiatively. The rest of the solar surface is constantly being replenished by convective cells that reheat it.
