Explain in your own words how chlorophyll makes a leaf look green

You may have noticed that there are plants which do not have green leaves.  Some plants are green because of a type of pigment called chlorophyll.   Plant cells contain chloroplast which constitutes the pigment chlorophyll. Chlorophyll absorbs red light and deep-blue light, hence, the rest of the sunlight spectrum which is being reflected causes the plant to look green.  When light reflects  off on leaves into your eyes, the leaves take in every hue of the rainbow, except for the color green, thus reflected into your eyes  and makes the leaves appear green.

For this case we must convert 26 seconds to hours,

By definition we have to:

1 hour equals 3600 seconds.

So, if we propose a rule of three we have:

1 hour ----------> 3600 seconds

x ------------------> 26 seconds

Where the variable "x" represents the number of hours equivalent to 26 seconds:

Thus, 26 seconds equals approximately 0.0072 hours.

0.0072 hours
