Claude is reading a science fiction book in which aliens have dropped a fungus on a 10 square
mile section of a planet. The fungus spreads
rapidly, increasing the area it covers by 50%
every hour. The total area of the planet is 200
million square miles. Claude created an equation
and determined that it will take approximately 41
hours for the fungus to cover planet. What is the
equation that Claude created?
Equation:

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.

(hint): the answer is in the question.
