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.

What slide organism in mitosis in plant cell?
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.
Is the root trip an ideal specimen for observing the phases of mitosis and why?
Yes, the root tip is an ideal specimen for observing the phases of mitosis because it contains rapidly dividing cells. The root tip, particularly in plants like onion, has a high concentration of meristematic tissue where cells are actively undergoing division. This makes it easier to capture and identify the distinct stages of mitosis, such as prophase, metaphase, anaphase, and telophase, under a microscope. Additionally, the relatively small size of the root tip allows for convenient preparation and observation.
Why are the onion root tip and the whitefish blastula useful tissue for the study of cell division?
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.
Why root tip of an onion is an ideal specimen for examining mitotic division?
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.
What are the properties of ideal chemotherapeutic agent?
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.

Why is onion good to observe mitosis?
Onions are commonly used to observe mitosis because their root tips contain rapidly dividing cells, making it easier to identify the stages of cell division. The tips are also rich in meristematic tissue, where cells are actively dividing. Furthermore, the large size of onion cells allows for clear visualization of the chromosomes during various phases of mitosis. This makes onions an ideal specimen for studying the process of cell division in a classroom or laboratory setting.

Why were plant root tip cells and animal embryo cells used for vieweing cell division?
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.

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.
What instrumet should be used to examine objects at greater than 200x?
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.
What are the properties of ideal chemotherapeutic agent?
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.
How is tertiary dentin formed by the application of calcium hydroxide?
i believe that the pulp has restorative cells like germ cells that can make new dentin if conditions are ideal
At what point in the cell life cycle is the best for photographing?
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.
How many unit cells are present in a cube shaped ideal crystal of NaCl of mass 1.00g?
