Vegetative propagation is practiced for growing some types of plants because of following advantages: 1. It is used to grow a plant in which viable seeds are not formed or very few seeds are produced such as Orange, Banana, Pineapple. 2.

Vegetative propagation is practiced for growing some types of plants because of following advantages:
1. It is used to grow a plant in which viable seeds are not formed or very few seeds are produced such as Orange, Banana, Pineapple.
2. It helps to introduce plants in new areas where the seed germination fails to produce mature plant due to change in environmental factors and the soil.→ It is more rapid, easier and cheaper method.
3. By this method a good quality of a race or variety can be preserved.
Higher complex organisms cannot give rise to new individuals through regeneration because complex organisms have organ-system level of organization. All the organ systems of their body work together as an interconnected unit. They can regenerate their lost body parts such as skin, muscles, blood, etRead more

DNA copying is an essential part of reproduction as it passes genetic information from parents to offspring. It determines the body design of an individual. The reproducing cells produce a copy of their DNA through some chemical reactions and result in two copies of DNA. The copying of DNA always taRead more
DNA copying is an essential part of reproduction as it passes genetic information from parents to offspring. It determines the body design of an individual. The reproducing cells produce a copy of their DNA through some chemical reactions and result in two copies of DNA. The copying of DNA always takes place along with the creation of additional cellular structure. This process is then followed by division of a cell to form two cells.
Advantages of spore formation: 1. Large numbers of spores are produced in one sporangium. 2. Spores are distributed easily by air to far-off places to avoid competition at one place. 3. Spores are covered by thick walls to prevent dehydration under unfavourable conditions.

In binary fission a single cell divides into two equal halves.Amoeba and Bacteria divide by binary fission. In multiple fission, a single cell divides into many daughter cells simultaneously. Plasmodium divide by multiple fission.
