Unlike most cells in an adult body, an embryonic mass of cells is always dividing. Most cells in the adult body is quiscent and will not divide unless signals have been given to them to divide, and many cells such as muscle and nerve cells have even lost the ability to divide.
The slide organism commonly used to study mitosis in plant cells is the onion root tip. Onion root tips have actively dividing cells that are easily observable under a microscope, making them ideal for studying the different stages of mitosis such as prophase, metaphase, anaphase, and telophase.
Root tips of allium cepa (otherwise known as the onion) are popularly used for cytological studies all over the world for the following reasons: 1) Roots are easy to grow from the base of the bulb kept over a water container. 2) Good quality, unsoiled root tips are easy to obtain. 3) Root tips have very rapid rate of mitosis. 4) The cells are very responsive to staining techniques. 5) The chromosomes are large and fewer in number. (Only 16 in a cell have the diploid condition. 8 is the haploid number.) 6) Fixing, staining, and ultimately making the slides permanent is easy in this material.
The root tip of an onion is an ideal specimen for examining mitotic division because it contains actively dividing cells at the root apex. These cells are in different stages of mitosis, making it easy to observe and study the process of cell division under a microscope. Additionally, onion cells have large, clear chromosomes that are easily visible, aiding in the observation of mitotic phases.
An ideal chemotherapeutic agent would selectively target cancer cells while sparing normal cells, have minimal side effects, be effective at killing cancer cells, have high specificity, be able to penetrate tumor tissues efficiently, and not lead to development of resistance.

Root tip cells in plants and embryo cells in animals are actively dividing cells, making them ideal for studying cell division processes. The rapid cell division in these cells allows researchers to observe different stages of mitosis or meiosis clearly. This can provide insights into the mechanisms and regulation of cell division processes.

To examine objects at greater than 200x magnification, a compound microscope is ideal. This instrument uses multiple lenses to achieve high levels of magnification and is suitable for observing small specimens like cells and microorganisms. For even higher magnifications, such as in the study of fine structures, an electron microscope may be used, which can exceed magnifications of 1000x.

i believe that the pulp has restorative cells like germ cells that can make new dentin if conditions are ideal

converts the chemical energy of a fuel and an oxzidizing into electricity.
The interphase stage, specifically during the G1 phase when the cell is preparing for DNA replication, is ideal for photographing cells. This is because the cell's structures are visible and distinct during this phase before the DNA condenses into chromosomes during mitosis.
Heat can definitely effects both types of cells. If cells become too hot or cold (or vary too far from their ideal temp.) they can denature and become useless.
