Mitochondria is also knows as “Powerhouses of the cell” because they produce energy in the form of ATP (Adenosine Triphosphate) to perform cellular activities. The cell need energy to perform various activities like respiration, growth, cell division protein synthesis etc. if we remove mitochondria in eukaryotic cell then cell lose it energy and doesn’t perform
Yes, white flowers may contain pigments but the they are very little in amount and having no colored pigments. That why they don’t show bright color like red, blue, yellow.
