“Tissues in Action” explains how similar cells group together to form tissues that perform special functions. Different tissues help organisms grow, move, transport materials, protect the body and coordinate activities. This division of labour increases efficiency and supports complex life ...
Improper mitosis can cause uncontrolled cell division, forming tumours. Faulty meiosis can lead to genetic disorders, abnormal chromosome numbers or reproductive problems in organisms.
Cells have many small mitochondria instead of one large one to increase surface area. More surface area allows faster energy production, efficient reactions and better distribution of energy throughout the cell.
If skin cells divide by meiosis, they would produce cells with half the chromosome number. This would disrupt normal repair and the cut would not heal properly.
