What effect do the cells surrounding a normal cell have on the cell's growth and division?
A "normal" cell does not divide into daughter cells without taking account of its environment. If energy sources are low in a medium, it will start a signaling system to suspend or even arrest the processes of the cell cycle. And if it makes contact with other cells---determined by proteins on the cell surface which may interact (bind specifically or nonspecifically) with the surface of the other cell (or its cell surface proteins), it may send a signal to do many things. Possibilities include arresting or even initiating a cell cycle (mitosis), altering its cytoskeleton (formation/deformation of microfiilaments and microtubules) to make a better fit or increase cell motility, or even altering its basic metabolism to acquire nutrients in a different manner or from an open (apical or basal) surface. In many cells, there is an inhibition ("contact inhibition") of the cell cycle when cell surfaces contact each other, which is why in culture growth is restricted to monolayers. Not in all cases...cancer cells may form piles or multilayers of cells and not be contact-inhibited.
What else can I help you with?
Is masrurbation effect my growth or height?
No, masturbation does not have any effect on your growth or height. These factors are primarily determined by genetics and overall health. Masturbation is a normal and healthy sexual activity that does not have any negative impact on physical development.
Does cell division speed up when healing process nears completion?
The rate of cell division slows down,controls on growth are restored, and everything returns to normal.
How are cancer cell growth differs from normal cell growth?
Cancer cell growth is uncontrolled, rapid, and does not respond to signals that typically regulate cell growth in normal cells. Normal cells have a regulated cell cycle with checks and balances to ensure controlled growth and division, whereas cancer cells have mutations that disrupt these regulatory mechanisms, allowing them to divide uncontrollably. Additionally, cancer cells can evade the body's immune system and can invade surrounding tissues or spread to distant organs, a process known as metastasis.
When cells are not responding to normal controls over growth and division they form tissue mass known as?
When cells are not responding to normal controls over growth and division, they can form tissue masses known as tumors. Tumors can be either benign (not cancerous) or malignant (cancerous).
Which cell is unorganized?
Cancer cells are unorganized, as they do not follow the normal growth and division patterns of healthy cells. This leads to unchecked growth and the formation of tumors.
What are factors that can effect the normal body temperature?
illness, excerise, surrounding, stress
What is uncontrolled cell division in a multicelluar animal?
Uncontrolled cell division in a multicellular animal is known as cancer. It occurs when normal regulatory mechanisms that control cell growth and division are disrupted, allowing cells to multiply uncontrollably. This can lead to the formation of tumors and the invasion of surrounding tissues.
How does cancerous cell growth differ from normal cell growth, and can you explain the key distinctions between the two processes?
Cancerous cell growth is different from normal cell growth because cancer cells divide uncontrollably and can invade surrounding tissues. Normal cell growth is tightly regulated and stops when the body doesn't need more cells. The key distinctions between the two processes are the uncontrolled division of cancer cells, their ability to spread to other parts of the body, and their resistance to signals that would normally stop cell growth.
When cells are not responding to normal controls over growth and division they form a tissue mass known as?
tumor

What are proto-oncogenes and how do they differ from oncogenes?
Proto-oncogenes are normal genes that help regulate cell growth and division. When mutated or altered, they can become oncogenes, which promote uncontrolled cell growth and can lead to cancer. The main difference is that proto-oncogenes are normal genes that can become oncogenes through mutations.

What is a part interphase?
g2 phase
What are the key differences between normal tissue and cancerous tissue?
Normal tissue and cancerous tissue differ in several key ways. Normal tissue follows a controlled growth pattern, while cancerous tissue grows uncontrollably. Normal cells have specific functions and structures, while cancer cells often lack these specialized features. Additionally, normal tissue responds to signals that regulate growth and division, whereas cancerous tissue ignores these signals. Finally, normal tissue typically remains localized, while cancerous tissue can invade surrounding tissues and spread to other parts of the body.
