All McIntosh apple trees are clones of an original tree found 150 years ago on the farm of John McIntosh in Ontario, Canada. This cloning has been accomplished by grafting. Find out more about grafting of plants. Strawberries grow from runners, stems that grow horizontally rather than vertically. Find out more about this type of vegetative propagation.
Spores are small bodies containing a nucleus and a small amount of cytoplasm.
Find out more about sporulation, the asexual production of spores. German biologist Theodor Boveri's experiments showed that heredity is a result of the nuclear material called chromosomes. Through the continuous process of cell division called mitosis, the blueprint material in chromosomes is duplicated. Use a biology text to find out more about Boveri's experiment and about the process of mitosis. How many steps are in the process.
