GENERAL HISTOLOGY

Detailed explanation-1: -Non-motile cilia known as primary cilia receive signals from nearby cells and act as antennae for the cells. Flagella help in locomotion in prokaryotic and eukaryotic cells. Flagella also act as sensory organs to detect temperature and pH changes.

Detailed explanation-2: -Flagellum is primarily a motility organelle that enables movement and chemotaxis. Bacteria can have one flagellum or several, and they can be either polar (one or several flagella at one spot) or peritrichous (several flagella all over the bacterium).

Detailed explanation-3: -Cilia are present in organisms such as paramecium, while flagella can be found in bacteria and sperm cells. Cilia are shorter and more numerous than flagella. Cilia and flagella are the most common organelles for locomotion in unicellular organisms. Organisms with cilia can move faster and more efficiently.
