Why do cells need to divide before they get too large?
They don't always divide, in multicellular organisms they typically just stop growing, in slime molds the cells can get more than a foot in diameter without dividing (they have tens of thousands of nuclei per cell).
What happens when cells do not stop growing?
When cells do not stop growing, it can lead to uncontrolled cell division and the formation of a tumor. This unregulated growth can disrupt the normal functions of tissues and organs, potentially leading to the development of cancer.
Why do cells in an embryo grow no larger than a certain size before they divide?
Cells in an embryo grow no larger than a certain size before they divide because as the cell grows, its surface area to volume ratio decreases. This leads to difficulties in nutrient exchange and waste removal, hindering the cell's ability to function properly. Dividing into smaller cells helps maintain an optimal surface area to volume ratio for efficient cellular processes.
Why do large cells divide?
Large cells divide primarily to maintain an efficient surface area-to-volume ratio. As a cell grows, its volume increases faster than its surface area, making it difficult to transport nutrients and waste effectively. Division allows cells to remain small enough to optimize these processes, ensuring proper function and survival. Additionally, cell division is essential for growth, development, and tissue repair in multicellular organisms.
Dr. Moore is growing skin cells in a petri dish. When the cells get too large they divide. When the cells detect that a space has become crowded they signal each other to?
stop dividing to prevent overcrowding, a process known as contact inhibition. This mechanism helps maintain proper tissue structure and function by regulating cell growth and division in response to the surrounding environment. As a result, the cells coordinate their behavior to ensure that they do not overpopulate the dish, allowing for healthy growth and maintenance of the cell culture.

Before a normal cell becomes too large to carry out normal activitiesit will usually divide to form two?
daughter cells
Before a normal cell becomes too large to carry out normal activities it will divide to form what?
Before a normal cell becomes too large, it will divide through a process called mitosis to form two identical daughter cells. This allows the cell to maintain a proper size and continue carrying out its normal activities efficiently.
Do your Cells grow as you grow?
yes, cells grow to an enlarged size and divide into two small cells (which each enlarge and divide as well). but the larger cells get, the more difficult it is for them to function and operate, so they remain within certain size boundaries, getting large enough to divide and halving, large enough to divide and halving.

How do cancer cells grow and divide?
Cancer cells divide excessively and invade other tissues. They do not have density dependence or anchorage dependence. Simply put, regular cells grow in an even layer while cancer cells grow tightly and on top of each other - an unnatural mass.
What is a rapidly growing population of identical cells that produce large quantities of specific antibodies called?
A rapidly growing population of identical cells that produce large quantities of specific antibodies is called a hybridoma. Hybridomas are created by fusing B cells that produce a specific antibody with myeloma (cancer) cells, allowing for the continuous production of the desired antibody. This process is crucial in making monoclonal antibodies, which have numerous applications in research, diagnostics, and therapy.
What are the Properties of meristematic tissue?
Meristematic tissues are cells or group of cells that have the ability to divide. These tissues in a plant comprise small, densely packed cells that can keep dividing to form new cells. Meristems have the following characteristics:The cells are small,The cells walls are thin,Cells have large nuclei,Vacuoles are absent or very smallThere are no intercellular spaces
To avoid growing too large cells regulate their size by?
Cells regulate their size through a process known as cell cycle control, which involves monitoring cell size and DNA content before proceeding to cell division. This control is mediated by various signaling pathways and checkpoints that ensure cells maintain an appropriate size for optimal function and survival. If cells grow too large, they can activate mechanisms such as apoptosis to eliminate themselves and prevent aberrant growth.
