The villi is part of a villus. The villus contains capillaries. The villus can absorb nutrients from the food in the small intestines, which is then transported to the capillaries. From there, nutrients from the food are transported throughout the body. The villi plays an important role in maintaining cellular homeostasis because without it, the food cannot be transported to the rest of the body and the body cannot maintain a stable amount of nutrients.
Root hair cells in plants:
The root hair cells in a plant work similarly to the villi cells in the small intestines. The root hair cell absorbs nutrients and mineral ions from the soil outside the cell and transports it to the rest of the plant. Also, it has a similar elongated shape as the villi cell, as the larger surface area enables more absorption. The root hair cells play an important role in maintaining cellular homeostasis because without it, the nutrients and mineral ions cannot be transported to the rest of the plant, and the plant would not be able to maintain a stable amount of nutrients.
