Question

1.Potato plants carry out photosynthesis to make molecules of glucose. If they can’t use all the glucose they make in a day, they store it as starch. Explain how they convert glucose to starch.
2.A few days later, a potato plants has not made enough glucose to feed itself for the day. Explain how it gets glucose from starch it is storing. (Include the name of the process it uses)

Answer 1

Answer:

Question 1

Answer ;

in photosynthesis process, the plant have the ability to absorb the light using their pigment called as chlorophyll.  this light energy with the help of many enzymes will help the conversion of CO2 and water in to glucose  which is then transported to different parts of the plants for its usage in different cellular processes and growth. The excess of glucose which is not utilized and metabolized immediately is converted to complex sugar molecules and stored in the plant in the form of Starch to fulfill the future needs.

Question 2

Answer ;

starch are stored for many purpose. the pathway used to create and store glucose in the form of starch is a reversible process. if potato plant have not made enough glucose for the day to feed itself, the starch which was stored will be catabolized using different cellular enzymes in to glucose.the starch which is stored is broken down and needed in those conditions and days when there is no sunlight or cloudy weather for days.
