1. Common Features of Animal and Plant Cells Cell Membrane Mitochondrion Nucleus Cell membrane Cytoplasm Ribosome Endoplasmic Reticulum Nucleolus Chromosome

2. Plant cells have three more structures than animal cells Cell wall - made up of cellulose it protects and supports the cell Chloroplast - contains chlorophyll (green pigment) used in photosynthesis Vacuole - stores water, food and waste products until they are needed. * A plant cells vacuole is much larger than an animal cells vacuole

4. Cells are the basic unit of structure and function in all living things. If you look inside cells, there are even smaller structures called organelles.

5. The Job of Each Organelle * Organelle – specific structure of a cell. Cell Membrane : covers the entire cell and acts as a gate keeper. Outer layer of cell. Decides what gets into and out of the cell. Nucleus: acts as a command or control center; directs all of the cell’s activities. It acts like a boss that hands out directions to the other cell parts.

6. Cell Structures Continued … Cytoplasm: nutrients are absorbed, transported and processed. Floats around the cells and carries organelles. Mitochondrion: oval shaped organelle that provides cells with energy. It breaks down food and releases energy. Nucleolus: found inside the nucleus of some cells; involved in the making of proteins.

7. Continued …. Endoplasmic reticulum: acts like a conveyor belt. It moves food, waste and water around the cell. Golgi apparatus: packs up and stores proteins until needed for use inside or outside the cell. Lysosome: breaks down food, cell waste and worn out cell parts.

8. Continued …. Chromosomes: thread like structures containing genetic information (DNA) Genes: genetic information that determines the specific characteristics of an individual Ribosome: builds proteins. Centriole: small protein structure important to cell division (found only in animal cells)
