The organism described could be a prokaryotic organism, specifically a type of bacteria. Here's why:

1. Unicellular: This means the organism is made up of only one cell. Both bacteria and archaea are examples of unicellular organisms.

2. Does not have a nucleus: This is a key characteristic of prokaryotic cells. Unlike eukaryotic cells, prokaryotic cells do not have a nucleus. Instead, their genetic material is freely floating in the cytoplasm.

3. Does not have chlorophyll: Chlorophyll is a pigment that allows organisms to perform photosynthesis by absorbing sunlight. Not all bacteria have chlorophyll. Those that do are called cyanobacteria or blue-green algae.

4. Has mitochondria: This is a bit tricky because traditionally, prokaryotic cells are not thought to have mitochondria. However, some recent research suggests that certain types of bacteria may contain structures similar to mitochondria.

5. Has a cell membrane: All cells, including prokaryotic cells, have a cell membrane. This is a thin layer that surrounds the cell and controls the movement of substances in and out of the cell.

So, based on these characteristics, the organism could be a type of bacteria. However, the presence of mitochondria is a bit unusual for bacteria and may suggest that the organism is a type of primitive eukaryotic cell. More information would be needed to make a definitive identification.
