TRANSPORT IN PLANTS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Glucose is converted to starch for transport in plants.
A
True
B
False
Explanation: 

Detailed explanation-1: -The sugar produced by photosynthesis can be converted into the sugar glucose. Thousands of glucose molecules can be linked together to form the complex carbohydrate starch. Starch is stored inside plant cells as grains.

Detailed explanation-2: -Glucose is stored as polymeric glucan, in animals as glycogen and in plants as starch. Despite serving a general source for metabolic energy and energy storage, glucose is the main building block for cellulose synthesis and represents the metabolic starting point of carboxylate-and amino acid synthesis.

Detailed explanation-3: -Glucose is converted into starch by the process called polymerization. In polymerization, several simple and soluble molecules of glucose are put together to form a complex, insoluble molecule of starch. Polymerization is similar to constructing a large building out of the same type of small blocks.

Detailed explanation-4: -Photosynthesis produces glucose in the green parts of plants, which are often leaves. This is then converted into sucrose. The sucrose is transported around the plant in phloem vessels.

Detailed explanation-5: -In photosynthesis, glucose is produced in plants. Glucose is immediately soluble and canot get stored but starch is insoluble. Thus it is converted into starch so that it cannot escape from the cells.
