Answer:
The main structural component of plant cell walls is cellulose which is a type of carbohydrate made up of a long chain of glucose molecules (a polysaccharide).
Explanation:
The plant cell walls are composed of cellulose, which is a structural carbohydrate made up of a long chain of glucose molecules (β linked D-glucose units). It is a polysaccharide like starch, but the starch molecule is flexible and the cellulose molecule is rigid. Each of these polysaccharide chains is connected together by hydrogen bonds. Microfibrils are formed by arranging some of these polysaccharide chains in parallel arrays. Due to the presence of hydrogen bonds, the microfibrils are extremely tough and inflexible. This property of cellulose provides strength and rigidity to the plant cell walls.
Answer:
The correct answer is high.
Explanation:
Hypotonic solution is a specific type of solution in which the concentration of water molecules is high than that of solute molecules present within that solution.
The correct answer is the letter C. acids.
An acid contains hydrogen that has the capability of donating proton (+) in a solution. So when an acid is dissolve in a solution, it releases hydogen ions.
No. Plants need animals to spread their seeds. Animals also loosen the ground for seeds or other forms of plants(not everything uses seeds right?) If animals didn't eat some plants certain plants would over populate some areas, killing off the other plant life (it has a fancy name I forgot it) and last of all deceased animals sometimes provide as nutrition for other plants.
