__________ play an important role in cell division, and they are made of __________.
Filtration; hydrostatic pressure. ___________is the process in which ________forces water and small solutes such as salts through narrow clefts between capillary cells. Cell Division role is if any injury happens the cell can divide quickly and repair the open area, or cut. the human body is made up of 200 different types of cells which are r…eplaced at different times. so if you do cut yourself the lower layer begin to divide , then new cells will fill the open area, and then the cells divide and repair the cut.

MADISON, Wis. -- Looking deep into the eye of a fly, University of Wisconsin researchers have found that a single protein orchestrates two fundamental biological processes ordinarily thought to be unrelated. Not only does it command certain cells to differentiate, it also helps regulate cell division. The finding, reported by scientists at the McArdle Laboratory for Cancer Research in the Jan. 10 issue of Science, may have important implications for understanding pancreatic and colon cancer. They appear in pairs in cells. Centrioles are involved in the production of the cytoskeleton and of cilia and flagella. In cell division, they play a role in the formation of aster fibers. Centrioles are structures present in animal cells, in most protists and in some primitive fungi. Explain the role of DNA plays in cell division? The nucleus is the part of the cell that directs the other organelles and everything the cell does, including cell division. There is only one thing that controls the nucleus,… and that's DNA. Without DNA, the cell would be able to do absolutly NOTHING, the DNA is like the brain of the cell. 3 people found this useful. As reported in Science, they recently found that in addition to regulating cell differentiation, DPP also synchronizes an entirely different biological process, cell division. In this multi-step cyclical process, cells make new DNA, copy it and then divide into two cells, thereby reproducing themselves. The division of the cytoplasm occurs after telophase and is called cytokinesis. In animal cells, an invagination of the plasma membrane toward center of the cell appears at the equator of the parent cell and then the cell is trapped in that region and divided into two daughter cells. hydrophobic; hydrophilic. Transmembrane proteins that make up enzymes in the plasma membrane are made up of hydrophilic and hydrophobic regions. Most amino acids embedded in the membrane are _____, while most amino acids facing the extracellular fluid are _____. Protein synthesis. False. These spindle fibers act as guides for the alignment of the chromosomes as they separate later during the process of cell division. Though centrioles play a role in the mitosis of animal cells, plant cells are able to reproduce without them. Researchers have, therefore, been very interested in determining exactly how important the organelles really are. Within the centrosome, the centrioles are positioned so that they are at right angles to each other, as illustrated in Figure 1. Each centriole is made of nine bundles of microtubules (three per bundle) arranged in a ring. Centrioles play a notable role in cell division. During interphase of an animal cell, the centrioles and other components of the centrosome are duplicated, though scientists are not yet sure how this duplication takes place.
