two variable u and v are connected by the equation 1/u +1/v =1/f where f is a constant. given that f=10 cm and u decreases at a rate of 2 cm per second. calculate the rate of increases of v when u=40cm​

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.
