Cell Types and Movement

Cells are the basic unit of life, with all living organisms consisting of at least one cell. They can be categorized into various types: eukaryotes, which contain a nucleus and membrane-bound organelles; prokaryotes, which are single-celled organisms lacking a nucleus; and multicellular organisms, which comprise many cells. Additionally, single-celled organisms can be classified as unicellular. Cell movement is facilitated by structures such as cilia, flagella, and pseudopodia, enabling various forms of locomotion.
