Tcecarenko [31]

In the plant, when a cell divides into two daughter cells, we observe in this experiment Mitosis, which is the cell division that allows the plant to elongate and occurs in the meristematic tissues that are at the ends of the plants. Whereas meiosis is restricted to reproductive tissue and forms gametes that will form new seeds through fertilization, carrying genes from one generation to another.

<h3>How does mitosis occur in plant cells?</h3>

In plant cells, division takes place from the inside out – centripetal cytokinesis. In plant cells, cytokinesis is centrifugal, from the outside to the inside: there is the formation of a lamella, which grows from the center to the periphery and separates the two cells.

With this information, we can conclude that through successive mitotic divisions that the zygote (cell generated after the meeting of gametes) manages to originate all the cells of its organism. Mitosis, therefore, is responsible for the growth and development of embryos.

Triss [41]

Among the tasks in coping with life-threatening illness described by Kenneth Doka, the chronic phase is characterized by "living with the disease".

Kenneth Doka (1995–96) divides the process of dying into three phases, namely the acute, the chronic, and the terminal phases of dying, during which the individual initially is given the diagnosis, then lives with the disease and ultimately surrenders to death.

This phase can be quite long and the supporters may become comfortable in their caregiving role and adjust to the notion of death. This is an important adaptation since a great deal of the care for the terminally ill is given by the family members.

Doka (1998) notes that this phase "is often a period of continued stress, punctuated by points of crisis".
