CELLS Structures and Functions (organelles and jobs) CELL MEMBRANE Surrounds and protects the cell Controls what gets in and out of the cell Gateway to the cell Door CYTOPLASM Liquidy substance inside every cell – the environment of the cell Flows or streams Gelatin (Jello) NUCLEUS Directs all activities in the cell Contains the instructions for everything a cell does DNA is inside the nucleus – chemical that has the codes/instructions Brain of the cell MITOCHONDRIA Release energy from food that is eaten Powerhouse of the cell Mit = mighty/power RIBOSOMES Make the proteins needed by the cell Manufacturing Plant – assembly line ENDOPLASMIC RETICULUM Moves materials around inside the cell Cell’s highway or roads or canal Golgi bodies Sort and package substances within the cell Move materials to the cell membrane to be eliminated Taxi Moving Company LYSOSOMES Recycle worn out products within the cell Recycling center VACUOLE Stores water, waste products, food, and other materials Storage shed – holding tank Cell wall Tough, rigid outer covering that protect the cell and give it shape Only found in plant cells, fungi and bacteria support = brick wall chloroplasts Contain green pigment called chlorophyll-which gives plant its green color Captures sunlight to make sugar by process of photosynthesis cells Two types of cells: 1. Eukaryotic –have a nucleus and other organelles 2. Prokaryotic –have NO nucleus, have cell membrane and ribosome, that’s it. cells Animal cell vacuole Plant cell lysosome Lets Compare Cells: Animal vs Plant Animal cell -Nucleus -Cell membrane -lysosome -ribosome -golgi bodies -ER -mitochondria -cytoplasm -vacuole Both Plant cell -Cell Wall -chloroplasts -Nucleus -Cell membrane -lysosome -ribosome -golgi bodies -ER -mitochondria -cytoplasm -vacuole What are similarities and differences between animal and plant cells Animal cell -peroxisomes Both Plant cell -Nucleus -Cell Wall -Cell membrane -chloroplasts -lysosome -ribosome -golgi bodies -ER -mitochondria -cytoplasm -vacuole Animal cell Both Plant cell -Nucleus -Cell membrane -peroxisomes -lysosome -Cell Wall -ribosome -chloroplasts -golgi bodies -vacuole -mitochondria -cytoplasm - ER
