Structures and Functions (organelles and jobs) 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 Both Plant cell -Cell Wall -chloroplasts -Nucleus -Cell membrane -lysosome -ribosome -golgi bodies -ER -mitochondria -cytoplasm -vacuole -Nucleus -Cell membrane -lysosome -ribosome -golgi bodies -ER -mitochondria -cytoplasm -vacuole

What are similarities and differences between animal and plant cells Animal cell Both Plant cell -Cell Wall -chloroplasts -peroxisomes -Nucleus -Cell membrane -lysosome -ribosome -golgi bodies -ER -mitochondria -cytoplasm -vacuole

Animal cell Both Plant cell -Nucleus -Cell membrane -lysosome -ribosome -golgi bodies -vacuole -mitochondria -cytoplasm - ER -peroxisomes -Cell Wall -chloroplasts
