Plant Cells contain extra structures such as a cell wall which provides support for the shape of the cell, chloroplasts which contain chlorophyll that absorbs light for photosynthesis and gives plants its green color, and vacuoles which contain a watery substance with dissolved sugars called cell sap that provides support for cell shape and stores sugars.
Nerve cells in Specialised Cells have branched endings called dendrites that communicate with many other nerve cells and long axons for electrical message travel.
White blood cells in Specialised Cells enable fighting infections, have a characteristic lobed nucleus, flexible cytoplasm for engulfing pathogens in phagocytosis, and some are specialised to produce antibodies.
