Answer:
Electron microscope
Explanation:
Instead of using light, it utilized a beam of electron for illumination. Because an electron beam has a shorter wavelength than light (up to 100, 000 times shorter), they have a higher resolution power and are therefore able to view sub-cellular structures including DNA.
The energy source of the sperm for them to swim is the protein breakdown by mitochondria in the midpiece of the sperm.
Mitochondria are double membrane-bound organelles found in the cells. It is said to be the "powerhouse of the cell". They provide ATP as a source of chemical energy for the cells.

The word "cycle" in cell cycle refers to the regular pattern of growth, DNA duplication, and cell division that occurs in eukaryotic cells.
The cell cycle is the term that describes the development and growth of a cell, after its formation and until its reproduction (division into two daughter cells). In eukaryotic cells (cells that include a nucleus) the cell cycle is comprised of two major phases, the interphase and the mitosis. During interphase, the cell grows larger and duplicates its genetic material. During mitosis, the cell divides its genetic material and cytoplasm, creating two daughter cells.
