Parts of a Eukaryotic Cell CELL WALL- A rigid structure that gives the support to a cell. It is the outermost part of a cell. CELL WALL- A rigid structure that gives the support to a cell. It is the outermost part of a cell. Plants have a cell wall made out of cellulose to help plants stand upright. Plants have a cell wall made out of cellulose to help plants stand upright.

Parts of a Eukaryotic Cell CELL MEMBRANE- A protective barrier that encloses a cell. CELL MEMBRANE- A protective barrier that encloses a cell. It separates the cell contents from the outside. It separates the cell contents from the outside. ALL CELLS HAVE A MEMBRANE! ALL CELLS HAVE A MEMBRANE! It’s made up of lipids and proteins. It’s made up of lipids and proteins.

Parts of a Eukaryotic Cell CYTOPLASM- A liquid web of proteins. CYTOPLASM- A liquid web of proteins. It helps keep cell membranes from collapsing. It helps keep cell membranes from collapsing. It also helps cells move. It also helps cells move. Suspends organelles Suspends organelles

Parts of a Eukaryotic Cell NUCLEUS- A large organelle that contains the cell’s DNA (genetic material). NUCLEUS- A large organelle that contains the cell’s DNA (genetic material). The nucleolus is a dark area inside the cell and makes ribosomes. The nucleolus is a dark area inside the cell and makes ribosomes.

Parts of a Eukaryotic Cell Ribosomes- The smallest of all organelles. Some are free floating and others are attached to membranes. Ribosomes- The smallest of all organelles. Some are free floating and others are attached to membranes. They make proteins They make proteins Proteins are made up of amino acids Proteins are made up of amino acids ALL cells have ribosomes ALL cells have ribosomes

Parts of a Eukaryotic Cell ENDOPLASMIC RETICULUM- (ER) A system of folded membranes in which proteins, lipids, and other materials are made. ENDOPLASMIC RETICULUM- (ER) A system of folded membranes in which proteins, lipids, and other materials are made. There is Rough ER and Smooth ER There is Rough ER and Smooth ER

Parts of a Eukaryotic Cell Rough ER is found near the nucleus Rough ER is found near the nucleus Ribosomes are found on the Rough ER and make proteins that are taken all over the cell. Ribosomes are found on the Rough ER and make proteins that are taken all over the cell. The Smooth ER lacks ribosomes. It makes lipids and breaks down toxins. The Smooth ER lacks ribosomes. It makes lipids and breaks down toxins.

Parts of a Eukaryotic Cell MITOCHONDRIA- The main power source in the cell. MITOCHONDRIA- The main power source in the cell. It breaks down sugar to produce energy. It breaks down sugar to produce energy. It stores energy as ATP. It stores energy as ATP. Most Eukaryotic cells have mitochondria Most Eukaryotic cells have mitochondria

Parts of a Eukaryotic Cell CHLOROPLAST- Organelle found in plant and algae cells in which photosynthesis takes place to make food. CHLOROPLAST- Organelle found in plant and algae cells in which photosynthesis takes place to make food. Photosynthesis is the process by which plants use sunlight, Carbon Dioxide, and water to make food. Photosynthesis is the process by which plants use sunlight, Carbon Dioxide, and water to make food.

Parts of a Eukaryotic Cell GOLGI APPARATUS- The organelle that packages and distributes proteins GOLGI APPARATUS- The organelle that packages and distributes proteins It looks like the Smooth ER It looks like the Smooth ER This membrane pinches off to form small bubbles that transport contents to other places in the cell This membrane pinches off to form small bubbles that transport contents to other places in the cell

Parts of a Eukaryotic Cell VESICLE- A small sac that surrounds material to be moved into or out of a cell. VESICLE- A small sac that surrounds material to be moved into or out of a cell. ALL Eukaryotic Cells have Vesicles ALL Eukaryotic Cells have Vesicles

Parts of a Eukaryotic Cell LYSOSOMES- Organelles that contain digestive enzymes LYSOSOMES- Organelles that contain digestive enzymes They destroy worn- out or damaged organelles, get rid of waste, and protect the cell from foreign invaders. They destroy worn- out or damaged organelles, get rid of waste, and protect the cell from foreign invaders.

Parts of a Eukaryotic Cell Vacuoles- A Large Vesicle that stores digestive enzymes and aid in digestion within the cell. Vacuoles- A Large Vesicle that stores digestive enzymes and aid in digestion within the cell. Some vacuoles store plant cells water and other liquids Some vacuoles store plant cells water and other liquids ONLY FOUND IN PLANTS! ONLY FOUND IN PLANTS!
