prepare a single introduction for cytoskeleton, cilia and flagella, centrosome and centrioles.
Answers
1) A cytoskeleton is present in the cytoplasm of all cells. It gives a cell its shape, offers support, and facilitates movement through three main components: microfilaments, intermediate filaments, and microtubules.
2) cilia is an organelle found in eukaryotic cells. Cilia are slender protuberances that project from the much larger cell body. There are two types of cilia: motile cilia, which beat against fluid outside the cell. non-motile, or primary cilia, which typically serve as sensory organelles.
3) flagella is a long, whip-like structure that helps some single celled organisms move. It is composed of microtubules. They help propel cells and organisms in a whip-like motion.It is surrounded by cell membrane.
4) centrosome is an organelle that is the main place where cell microtubules are organized. Also, it regulates the cell division cycle, the stages which lead up to one cell dividing in two.
5) A centriole is a small set of microtubules. It helps in the formation of the spindle fibers that separate the chromosomes during cell division
