FAQs on Variety in Shape of Cells Video Lecture - Science Olympiad Class 8
| 1. What are the different shapes of cells? |  |
Ans. Cells can have a variety of shapes, including round, elongated, flat, cuboidal, and irregular. The shape of a cell is determined by its function and the specific tissue or organ it belongs to.
| 2. How does the shape of a cell relate to its function? | |
Ans. The shape of a cell is closely related to its function. For example, flat cells, such as those found in the skin, provide a protective barrier. Elongated cells, like muscle cells, allow for contraction and movement. Cuboidal cells, found in glands, have a shape that facilitates secretion. The specific shape of a cell allows it to carry out its specialized function effectively.
| 3. Why do cells have different shapes? | |
Ans. Cells have different shapes because they serve different functions in the body. The shape of a cell is determined by its internal structure and the role it plays in the overall function of the tissue or organ it belongs to. Different shapes allow cells to perform specific tasks more efficiently.
| 4. Can the shape of a cell change? | |
Ans. Yes, the shape of a cell can change depending on its physiological state or external conditions. For example, red blood cells can change their shape to squeeze through narrow capillaries. Some cells can also change their shape during processes like cell division or migration.
| 5. How does the shape of a cell impact its movement? | |
Ans. The shape of a cell can impact its movement by influencing its ability to squeeze through narrow spaces or propel itself forward. For example, elongated cells like sperm cells have a streamlined shape that allows them to swim efficiently. On the other hand, round cells may have a slower and more limited ability to move due to their shape.
