Who found that the green parts in plants is where glucose is made, and that the glucose is usually stored as starch?

A

Julius von Sachs

B

Cornelius van Niel

C

T.W. Engelmann

D

Jan Ingenhousz

Text Solution

Verified by Experts

The correct Answer is:
A
Mayer found that organic matter is synthesised with the help of solar energy
.It was not until about 1854 that Julius von Sachs provided evidence for production of glucose when plants grow.
.Sachs found that the green parts in plants is where glucose is formed and glucose is usually stored as starch.
Glucose is not stored in plants as it increases the osmotic pressure. His later studies showed that the green substance in plants (chlorophyll as we know it now) is located in special bodies (later called chloroplasts) within plant cells.

Read the passage given below and answer the question: Polysaccharides may be very large molecules. Starch, glycogen, cellulose, and chitin are examples of polysaccharides. Starch is the stored form of sugars in plants and is made up of amylose and amylopectin (both polymers of glucose). Amylose is soluble in water and can be hydrolyzed into glucose units breaking glycocidic bonds, by the enzymes a- amylase and B-amylase. It is straight chain polymer. Amylopectin is a branched chain polymer of several D-glucose molecules. 80% of amylopectin is present in starch. Plants are able to synthesize glucose, and the excess glucose is stored as starch in different plant parts, including roots and seeds. The starch that is consumed by animals is broken down into smaller molecules, such as glucose. The cells can then absorb the glucose. Glycogen is the storage form of glucose in humans and other vertebrates, and is made up of monomers of glucose. It is structurally quite similar to amylopectin. Glycogen is the animal equivalent of starch. It is stored in liver and skeletal muscles. Cellulose is one of the most abundant natural biopolymers. The cell walls of plants are mostly made of cellulose, which provides structural support to the cell. Wood and paper are mostly cellulosic in nature. Like amylose, cellulose is a linear polymer of glucose. Cellulose is made up of glucose monomers that are linked by bonds between particular carbon atoms in the glucose molecule.Every other glucose monomer in cellulose is flipped over and packed tightly as extended long chains. This gives cellulose its rigidity and high tensile strength-which is so important to plant cells. Cellulose passing through our digestive system is called dietary fiber.
