Round 6.7493 to 2 significant figures

6.75

Step-by-step explanation:

Since, when we rounded a decimal number to 2 significant figures,

We check the thousandth digit, ( third digit after decimal )

If thousandth digit is less than 5 then the hundredth digit ( second digit after decimal ) will be rounded to preceding number while if it is 5 or more than 5 then the hundredth digit will be rounded to succeeding number,

∵ 9 > 5

Hence, 6.7493 ≈ 6.75

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.
