thing made from another‚ leading to two organisms with the same set of genes. In that sense‚ identical twins are clones‚ because they have identical DNA. Sometimes‚ plants are self-pollinated‚ producing seeds and eventually more plants with the same genetic code. Some forests are made entirely of trees originating from one single plant; the original tree spread its roots‚ which later sprouted new trees. When earthworms are cut in half‚ they regenerate the missing parts of their bodies‚ leading to

Introduction: The purpose of the plant growth experiment was to test the affect of plant fertilizer during plant growth. The system we were working with allowed us to test the recommended amount and double the recommended amount of Miracle Grow in comparison to a control of an all natural growing plant. The plants we were testing were radishes We decided on testing the validity of Miracle Grow with radishes to determine if fertilizers are worth purchasing. Hypothesis: If the recommended amount

The physiological definition of growth is “An irreversible change in the organism‚ organ or cell is called growth”‚ which includes increase in mass weight or volume of living organism‚ it leads to development in plants. REGION OF GROWTH: Growth region is located at extreme apices of root‚ stem‚ leaf where we make out meristematic tissue. In addition to above‚ the region where intercalary and lateral meristem is present is also considered as growth region. PHASES
