The inner mitochondrial membrane is semipermeable and regulates the passage of materials into and out of the mitochondria. It usually produces numerous infolds called cristae. The cristae extend inward to varying degrees and may fuse with those from the opposite side, dividing the mitochondria into compartments.
A cell is derived as the functional and structural unit of life. Every cell is surrounded by a cell membrane that dissects the external and internal environments of the cell. The interior environment of a cell is called the cytoplasm.
It carries cellular machinery and structural elements. The nucleus is present in the center of the cell, which includes all the hereditary information of an organism. Some of the molecules present in the cell are protein, carbohydrates, starch, and sugar.
