Plant cells have cell walls and vacuoles.
The cell wall and the vacuole is what keeps the plant standing up.
The cell wall is a rigid layer outside of the cell.
The vacuole is a space within the cell that contains water. When the plant has a lot of water, it will be rigid and stand up right. If you do not water your plant well, the plant may lose its rigidity.
Answer:
All carbohydrates have the general formula Cn(H2O)n
Explanation:
The basic unit of carbohydrates-monosaccharides have the formula C
nH
2nO
n while the basic general formula of carbohydrates is Cm(H2O)n .
Monosaccharides are basic units (components) of carbohydrates. Those are simple sugars such as glucose, fructose, galactose. Two monosaccharides can join together via glycosylic bond and make disaccharides. Some of the disaccharides are: sucrose (glucose + fructose), lactose (galactose + glucose), maltose (glucose + glucose).
Disaccharides can be broken down to monosaccharides by an enzyme called a disaccharidase.
Longer chains of monosaccharides form oligosaccharides (usually as glycolipids ) and polysaccharides (starch, glycogen,cellulose, chitin).
Carbohyrates are important biomolecules included in metabolism, energy storage, they are also structural components, have role in immune response, as coenzymes etc.
