CELL SPECIALIZATION ❑Also known as Cell Differentiation ❑It is the process by which generic cells change to different types of cells to be able to perform special or specific functions. Source: https://en.wikipedia.org/wiki/Cellular_differentiation  SPECIALIZED CELLS IN ANIMALS Function: It carry oxygen throughout the body Characteristics: No nucleus, biconcave shape, Red Blood Cell contains  SPECIALIZED CELLS IN ANIMALS Function: It play an important role in the immune system Characteristics: Irregular shape White Blood Cell Can produce antibodies and  SPECIALIZED CELLS IN ANIMALS Function: Fertilize an egg cell Characteristics: Long tail to swim Numerous mitochondria Sperm Cell With chemicals on the head for egg cell entry  SPECIALIZED CELLS IN ANIMALS Function: Carries genetic material Characteristics: Large and bulky A chemical change in Egg cell the membrane prevents fertilization of more than one sperm  SPECIALIZED CELLS IN ANIMALS Function: Carry nerve impulses through body Characteristics: Long, thin axon Branching dendrites Nerve cell myelinated or neuron  SPECIALIZED CELLS IN ANIMALS Function: Facilitate movement Characteristics: Elongated and elastic Numerous mitochondria Muscle cell  SPECIALIZED CELLS IN PLANTS Function: Regulates rate of transpiration Characteristics: Cell wall has varying Guard cell thickness  SPECIALIZED CELLS IN PLANTS Function: Produces food through the process of photosynthesis Characteristics: Contains numerous of Photosynthetic chloroplasts cells CELL MODIFICATIONS ❑adaptation or changes acquired by the cell after the cell division that aids the cell in various beneficial ways. CILIA Hair-like structures extending from the cell surface. Types of Cilia Non-motile- or Primary cilia (sensory) Motile (movement) mucosal lining of the fallopian tube FLAGELLA ✔ FLAGELLA Long whip-like structures For locomotion VILLI or MICROVILLI -small, slender, finger-like projections -increases surface area to increase absorption STEREOCILIA -non-motile modified microvilli -Found: ears (cochlea) male reproductive part PSEUDOPODS -”false feet” -temporary extension of the cytoplasm -movement and ingestion
