20 points about animal cell
Answers
HI FRIEND
Fact 1: In general, animal cells are eukaryotic which means they have a nucleus. Not all animal cells do have a nucleus, however. The red blood cells, for example, do not have a nucleus since the cells do not need to replicate in meiosis or mitosis, they do not need a nucleus. The lack of a nucleus allows them to hold more hemoglobin within the cell.
Fact 2: Some animal cells may swim when necessary. Protozoans are examples of cells that are able to swim. In addition, sperm cells that have the male gamete can swim too. Once they are released they swim in the uterus towards the ova and merge with it.
Fact 3: In animals the stem cells are totipotent. This means they can transform the body needs into any necessary cell.
Fact 4: During the daily activity, among other things the cell may face some malfunction in the strands of RNA and DNA. The cell has the functionality to automatically fix such malfunctions by itself.
Fact 5: No that doesn't simply mean the cells are immediately self-destructing. If a cell is damaged or has DNA defects, it will self-destruct, so that it will not harm other cells.
Fact 6: 70 per cent of the cell is water while the rest is starch, protein, lipid, etc.
Fact 7: Cells have nan chemical factories which provide all it needs. These factories produce whatever the cell needs to do so it can do the required work.
Fact 8: Animal cells are not visible to the naked eye just like any cell.
Fact 9: The cytoskeleton helps keep the cell in shape. It is located inside the cell's cytoplasm which consists of proteins.
Fact 10: The nucleus within a cell is the most important element and there is therefore a misconception that it is always contained in the center of the cell. This is not always true in any part of the cell the nucleus can be found in.
