- It can be identified as bean shape or bread-like oval shape organelle
- it has two membranes outer membrane and the inner membrane is thrown into various types of folds called cristae is a distinguishable feature.
- these folds are tubular in plant cells and plate-like in animal and fungal cells.
- The inner membrane bears functional unit, beads like oxysomes
- Oxysomes take part in ATP synthesis
