These specialized nerve cellsare thin, and more than 1 meter long and have extensions called dendrites and axons, that help carry out communicative functions from one neuron to another. Probably the simplest plant is algae. Specialised cells are cells that have developed certain characteristics to perform a particular function. Some specialized these cells also contain chemicals for electrochemical communication and have a fatty (myelin) sheath, which increases the travel speed of the messages. All of the specialized cells in the body come from the same originating tissue: the group of stem cells that make up the earliest stages of an embryo. Each of the specialized cells has a definite role. Groups of specialised cells that carry out particular functions are called tissues. Each tissue type has a specific job based on where it is located in the body. The phloem is specialised to transport food products to parts of the plant where they are needed. These cells are commonly found in leaves, roots, and stems, usually having a spherical shape with only primary cell walls and highly functional cytoplasm.
