2. How does this experiment demonstrate the need for larger cells to divide? As a cell gets bigger, the outside is unable to keep up with the inside, because the inside grows a faster rate than the outside.…
The main requirements for the growth of micro organisms are time and moisture, some need oxygen and warmth to be able to grow properly.…
contrast the reasons cell division is important for unicellular and multicellular organisms. Cell division is the method in which single celled organisms reproduce. Cell division allows multi-cellular to grow and repair dead or damaged cells…
Cells are not larger that 1000 um because of the structure of a cell it wouldn’t be possible to make a large ball of thickly solute fluid out of a skin of fatty membrane. The cytoskeleton is built to just take on a certain amount of space size wise, it could fall apart. In addition. Genes and hormones tell how a cell is made, the factors serve to regulate the cell size and prevent its rapid and undifferentiated growth. For example, cancer is what happens when a cell keeps growing. Genes are so smart that they make the codes for cells and its job is to make the codes that keep the cell functioning. Genes evolved to find the best cell size that would give the best size, energy, and structural features for a…
1. Cells reproduce by splitting in half, a process called cell division. What do cells need to do between divisions to make sure that they don’t just get smaller and smaller?…
The cell theory- The ability of cells to divide to form new cells is the basis for all reproduction and for the growth and repair of multicellular organisms, including humans.…
How does the size of a cell affect the distribution of chemicals throughout the cell?…
proliferation, reproduction or multiplication of cells, important with cancer because cancer causes cells to go haywire and then they proliferate, often at an increased rate…
Different parts of the body of an organism have been observed to grow at different rates during development. When parts of the body grow disproportionately to one-another, we call it allometric growth. The term, isometric growth, is used when describing body parts which maintain the same ratio throughout development.…
8. Name the phase of the cell cycle in which cells spend most of their time doing their job.…
Cells divide for two main reasons: first, the larger a cell becomes, the more demands the cell has on its DNA. Second, a large cell has more trouble moving enough food in and enough waste out. Before it becomes too large, a growing cell divides. The two new cells are referred to as daughter cells. The process by which a cell divides into two cells is called cell division.…
Cells and organisms exchange matter with the environment. For example, water and nutrients are used in the synthesis of new molecules; carbon moves from the environment to organisms where it is incorporated into carbohydrates, proteins, nucleic acids or fats; and oxygen is necessary for more efficient free energy use in cellular respiration. These processes release matter to the environment as waste products. For example, cellular respiration will release carbon dioxide. In addition, programmed cell death (apoptosis) plays a role in normal development and differentiation (e.g., morphogenesis). Differences in surface-to-volume ratios affect the capacity of a biological system to obtain resources and eliminate wastes.…
Cell division occurs when cells are dividing in order to produce new cells. I have compared the differences between cancer and good cell division to find out the process of division of all cells, this is also when I found that there are different more complicated chromosomes in cancer cells. One of the main problems with cancer cells comparing is the chance of tumor formation which leads to the invasion of cancerous cells. Another consequence is the cancer spreading to other organs. A tumor consists of a mass of cancer cells in the tissue. Usually an evasive tumor is malignant, causing cells to develop in the blood. Tumors invade growth that the tissue and organs need to survive.…
Growth in biological systems is defined as the accumulation of mass, which leads to an increase in size. In this article, we discuss how cells, organs, and organisms normally control growth, and how deregulated growth can lead to a variety of pathological conditions.…
