Detailed Solution

A plant cell is 0.00001275 m. The size in standard form is 1.275× 10 5 m  .
Given that,
Size of a plant cell = 0.00001275 m.
We know standard form is a way of representing a number as a product of decimal numbers and powers of 10.
The number 0.00001275 contains 4 zeros after the decimal point and is less than 1.
So, the power is negative in nature.
If we include the first non-zero digit after the decimal point, then power of 10 will be -5.
So, 0.00001275=1.275× 10 5  .
Therefore, plant’s cell size in standard form is 1.275× 10 5 m  .
