Animal cells are Eukaryota, so they are not the first examples of cells.
Archaebacteria, though they are possibly more closely related to eukaryote than bacteria are, do possess more of the hypothesis ancient methods of energy production (like thermoautotrophism and chemotherapeutic) which were prevalent before photosynthesis and aerobic respiration.
Mitochondria are related to bacteria (specifically purple photosynthetic bacteria), and they perform aerobic respiration. Aerobic respiration cannot have been the original method for deriving energy, as it required oxygen - which was not abundant in the atmosphere until photosynthesis evolved.
Chloroplasts are also related to bacteria (cyanobacteria) and they perform photosynthesis. It is currently believed that photosynthesis was not one of the original methods for deriving energy.
So my answer would be archaebacteria.
Bacteria were the first cells.
Scientists first thought of them as small animals. They first observed cells using the microscope and the work of many scientists led to the development of the cell theory.

Cells were first discovered by Robert Hooke in 1665 while examining a slice of cork through his self designed microscope.

The development of quality optical lenses allowed the making of microscopes, which permitted scientists to see things as small as typical cells for the first time in human history.
