Totipotent cells formed during sexual and asexual reproduction include spores and zygotes. Zygotes are the products of the fusion of two gametes. In some organisms‚ cells can dedifferentiate and regain totipotency. For example‚ a plant cutting or callus can be used to grow an entire plant. Human development begins when a sperm fertilizes an egg and creates a single totipotent cell called zygote. In the first hours after fertilization‚ this cell divides into identical totipotent cells. Approximately four days

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 OF GROWTH: Growth is a complex process

Some of the most bizarre and fascinating plants in the natural world are undoubtedly carnivorous plants. Carnivory‚ defined as the consumption of animal tissue‚ is often only associated with the animal kingdom. However the existence of carnivory is widespread and diverse in the plant and fungi kingdoms as well. Specifically carnivorous plants‚ which originally descended from exclusively photosynthetic plants‚ have evolved elaborate‚ efficient‚ and diverse methods to capture‚ digest‚ and metabolize

Water Transport in Plants Introduction In this lab experiment‚ we set out to examine the different transpiration rates of a plant system in certain environments. Water is transported in a plant by the process of transpiration‚ which is the loss of water through evaporation from the surface of leaves. The stomata in leaves are responsible for the diffusion of water vapor. Transpiration brings water upward through the xylem in the plant. There are certain factors that can affect transpiration
