1. A minute cylindrical organelle near the nucleus in animal cells, occurring in pairs and involved in the development of spindle fibers in cell division.
2. Centrioles are paired barrel-shaped organelles located in the cytoplasm of animal cells near the nuclear envelope.
3. Centrioles play a role in organizing microtubules that serve as the cell’s skeletal system.
4. They help determine the locations of the nucleus and other organelles within the cell.
Biological interaction is the effect that a pair of organisms living together in a community have on each other. They can be either of the same species (intraspecific interactions), or of different species (interspecific interactions). These effects may be short-term, like pollination and predation, or long-term; both often strongly influence the evolution of the species involved. A long-term interaction is called a symbiosis. Symbioses range from mutualism, beneficial to both partners, to competition, harmful to both partners.[1] Interactions can be indirect, through intermediaries such as shared resources or common enemies.
