Question

Can microtubules be used in/for the following roles? For each role

answer yes or no.
1) movement
2) cytokinesis
3) extracellular transport
4) cell crawling
5) absorbtion of nutrients in the intestines

Answer 1

Yes, microtubules can play various roles in cells, including movement, cytokinesis, extracellular transport, cell crawling, and absorption of nutrients in the intestines.

Step-by-step explanation:

Yes, microtubules can be used in several roles:

1. Movement: Microtubules are involved in intracellular motility, enabling cell movement and cytoplasmic streaming inside cells.
2. Cytokinesis: Microtubules play a crucial role in cell division by setting the paths along which the genetic material is pulled, ensuring each new daughter cell receives the appropriate set of chromosomes.
3. Extracellular transport: Motor proteins like dynein and kinesin utilize microtubules to move cargo from one place to another inside cells. This includes vesicles and organelles that need to be transported to specific locations.
4. Cell crawling: Microtubules are involved in cell crawling, enabling cells to move from one place to another.
5. Absorption of nutrients in the intestines: While microvilli in the intestines are primarily composed of actin microfilaments, microtubules contribute by providing strength and enabling microvilli to move independently.
