The Significance of Stem Cells A stem cell is a cell that can divide (by mitosis) an unlimited number of times Each new cell (produced when a stem cell divides) has the potential to remain a stem c...
The Significance of Telomeres The ends of the chromatids in chromosomes are ‘sealed’ with protective structures called telomeres They are made of non-coding DNA (DNA that does not contain genes) th...
The Cell Cycle Mitosis is part of a precisely controlled process known as the cell cycle The cell cycle is the regulated sequence of events that occurs between one cell division and the next The ce...
The Importance of Mitosis Mitosis is the process of nuclear division by which two genetically identical daughter nuclei are produced that are also genetically identical to the parent nucleus The pr...
Chromosome Structure Chromosomes are made of one very long, condensed DNA molecule associated with proteins (in eukaryotic cells) The main proteins present are the large positively charged globular...
Osmosis in Cells: Comparison Comparing & Contrasting the Movement of Water by Osmosis in Plant & Animal Cells Table 转载自savemyexams
Osmosis: Animal Cells Osmosis is the net movement of water molecules from a region of higher water potential (dilute solution) to a region of lower water potential (concentrated solution), through ...
Osmosis: Plant Cells Osmosis is the net movement of water molecules from a region of higher water potential (dilute solution) to a region of lower water potential (concentrated solution), through a...
Estimating Water Potential in Plant Tissue It is possible to investigate the effects of immersing plant tissue in solutions of different water potentials and then use the results to estimate the wa...
