Organelles like mitochondria and the Golgi apparatus are found in eukaryotic cells.
-
Mitochondria: These are often referred to as the "powerhouses of the cell" because they are responsible for producing adenosine triphosphate (ATP), the energy currency of the cell. Mitochondria are typically found in the cytoplasm of almost all eukaryotic cells, including those of animals, plants, fungi, and protists.
-
Golgi apparatus: This organelle is involved in the modification, sorting, and packaging of proteins and lipids for secretion or for use within the cell. Like mitochondria, the Golgi apparatus is found in the cytoplasm of eukaryotic cells and is usually situated near the endoplasmic reticulum (ER), where it receives vesicles containing proteins and lipids.
In contrast, prokaryotic cells (such as bacteria and archaea) do not have these organelles; they lack a defined nucleus and membrane-bound organelles.
