ESSENTIAL QUESTION: WHAT ARE THE STRUCTURES AND FUNCTIONS OF PLANT AND ANIMAL CELLS? DIFFERENCES BETWEEN PLANT & ANIMAL CELLS Shape: - Plant: rectangular - Animal: circular Cell Wall: - Plant: rigid Cell Wall that surrounds the cell - Animal: do not have Chloroplasts: - Plant: converts sunlight into food - Animal: do not have Vacuoles: - Plant: have 1 large Vacuole - Animal: have several smaller Vacuoles GLUE IN A LABEL PLANT CELL A. B. C. D. E. F. G. Cytoplasm Chloroplast Nucleus Mitochondria Cell Wall Cell Membrane Vacuole GLUE IN A LABEL ANIMAL CELL A. Mitochondria B. Cell Membrane C. Cytoplasm D. Vacuole E. Nucleus CELLS FUNCTIONS • Cytoplasm Thick, jelly-like substance Holds cell organelles in place inside the cell Helps support & protect the cell’s organelles CELLS FUNCTIONS • Cell Membrane Function is to regulate the transfer of material in & out of the cell Maintains homeostasis CELLS FUNCTIONS • Nucleus Round, double-walled structure Found in the center of plant/animal cells Function is to contain genetic material Controls cell’s activity CELLS FUNCTIONS • Mitochondria Function is to produce energy for cellular functions Breaks down sugar (glucose) to produce energy Known as the Power House of the cell CELLS FUNCTIONS • Vacuoles Round in shape Bigger in plants, smaller & several in animals Function is to store water, waste, & nutrients for the cell In Plants stores mostly water CELLS FUNCTIONS • Chloroplasts Oval discs with green chlorophyll Found in plant cells Function is to use the energy from the sun (photosynthesis) to make food (glucose) & oxygen CELLS FUNCTIONS • Cell Wall Rigid outer layer of plant cells Function is to help maintain its shape under the changing water pressure Supports & Protects
