It appears as two electrondense lines separated by an electron-lucent intermediate zone. Therefore, it has a trilaminar appearance and called unit membrane. - Multiple mitochondria of different sizes and shapes: - Outer mitochondrial membrane (1) - Inner mitochondrial membrane (2) - Cristae (3) - Ma...
