Eukaryotic Cell Structure Most organisms are eukaryotes. Cell Wall • found in plants, algae, fungi, bacteria • Rigid; protects and supports • contains cellulose for structure • surrounds cell membrane Cell Membrane 1. 2. 3. Animal Cell cytoplasm cell membrane nucleolus chromatin nuclear membrane Plant Cell nucleus nucleolus chromatin nuclear membrane cell wall cell membrane cytoplasm Types (both in all cells): 1. smooth E R – lipid synthesis, neutralizes poisons 2. rough E R – has ribosomes, transports protein Ribosomes • site of protein synthesis • found on rough E.R. and free floating in the cytoplasm Animal Cell cytoplasm cell membrane smooth ER nucleolus chromatin ribosome rough ER nuclear membrane Plant Cell smooth ER nucleus nucleolus chromatin nuclear membrane cell wall cell membrane rough ER ribosome cytoplasm Golgi complex • packages and distributes protein • forms small membrane sacs known as vesicles vesicle Mitochondrion • “power house” • respiration centers of cell (breaks down glucose to release stored energy) Mitochondrion • produces energy (ATP) • structure – inner folded membrane for more surface area = more energy produced • have there own DNA • can divide to make more energy • ex: muscle cells have large amounts of mitochondria because they need a lot of ATP Chloroplasts • found in plant and algae cells • contain a green pigment called chlorophyll • where photosynthesis takes place Animal Cell cytoplasm cell membrane smooth ER nucleolus chromatin ribosome mitochondria Golgi complex rough ER nuclear membrane Plant Cell smooth ER nucleus nucleolus chromatin chloroplast nuclear membrane Golgi complex cell wall cell membrane rough ER mitochondria ribosome cytoplasm Lysosomes • “suicide sacs” • vesicles which contain digestive enzymes • digests food particles, kills bacteria, destroys worn out cells and organelles, degenerates tissue • found in animal cells White blood cells have a lot of lysosomes to digest bacteria. Vesicles • small sacs used to transport material around the cell Vacuole • large storage compartments for enzymes, waste, water, sap • found in plant cells Animal Cell cytoplasm vesicle cell membrane smooth ER nucleolus chromatin ribosome mitochondria Golgi complex rough ER nuclear membrane lysosome Plant Cell smooth ER nucleus nucleolus chromatin chloroplast nuclear membrane Golgi complex cell wall cell membrane rough ER vacuole mitochondria ribosome cytoplasm
