Science 10 – C2.1 The Cell NG Name: _______________________ Date: ___________________ 1. Define organelles. 2. Cells are open systems. Define an open system. 3. Identify the seven life processes that cells carry out. Classifying Cells – Prokaryotic or Eukaryotic Cells? Here is a summary of the characteristics of prokaryotic and eukaryotic cells: 1. 2. 3. 4. Prokaryotic Cells no nucleus – nuclear material is dispersed throughout cytoplasm membrane-bound organelles absent – no mitochondria, lysosomes, ER, chloroplasts, centrioles, Golgi apparatus chlorophyll, if present, is not in chloroplasts consist of members of kingdom Monera – e.g., bacteria and blue-green algae Eukaryotic Cells 1. nucleus present and separate from cytoplasm 2. all membrane-bound organelles present 3. chlorophyll, if present, is found in chloroplasts 4. members of kingdoms Protista (protozoans e.g., amoeba), Fungi (algae and fungi), Plantae (plants), Animalia (animals, humans) Classifying Cells – Plant or Animal Cells? 4. Use the generalized plant cell above and on text p. 270 to label the diagram below. 5. Use the generalized animal cell above and on text p. 270 to label the diagram below. 6. Compare and contrast plant and animal cells. Complete the Venn diagram below. Plant Cells Animal Cells Both Plants And Animals 7. Complete the following table. Use pages 267–269 of your textbook. Organelle cell membrane cytoplasm Function(s) Present in Plant Animal cells cells Organelle Function(s) nucleus nuclear pores: tiny holes in the nuclear membrane that allow substances into and out of the nucleus nucleolus: Vacuoles and vesicles vacuoles: vesicles: endoplasmic reticulum (ER) rough ER: smooth ER: mitochondrion (plural: mitochondria) Present in Plant Animal cells cells Organelle Function(s) cell wall chloroplasts chlorophyll: Golgi apparatus ribosomes lysosomes centrioles cytoskeleton cilia and flagellum cilia = fine hairlike structures on the surface of some cells that aids in movement (motility) flagellum = whiplike tail on some cells that aids in movement (motility) Present in Plant Animal cells cells
