Presentation Transcript

  1. The animal Cell

  2. What is a cell?

  3. “cell” is! • The Cell - basic unit of structure & function in the organism; most cell are vary small and invisible without using a microscope.

  4. Cell Theory 1. Every living organism is composed of cells. 2. Every cell in an organism produced by anther cell.

  5. Cell Structure

  6. Cell Membrane Structure: • Surround the parts of cell together. Function (job): • Controls the movement of material into and out of cell.

  7. Cytoplasm Structure: • Substance between the cell membrane and the nucleus.(Everything within the cell membrane which is not the nucleus is known as the cytoplasm). • Makes up most of the mass of many cell. Function (job): • Different cell material are produced by cytoplasm.

  8. Cytoplasm Cytosol is the jelly-like mixture in which the other organelles are suspended, so cytosol + organelles = cytoplasm.

  9. Nucleus Structure: • Usually round/oval • Near center The nucleus separated from the cytoplasm by a thin membrane is called nuclear membrane.

  10. Nucleus Function (job): • Controls cell activities

  11. Mitochondria Structure: • Rod shaped

  12. Mitochondria Function (job): • Release energy & it is called (Power house of cell)

  13. Ribosomes Structure: • Tiny particle, so small, they can see only with an electron microscope.

  14. Ribosomes Function (job): • Site of Protein synthesis because it consisting of RNA and protein.

  15. Endoplasmic Reticulum Structure: • Like tubes • Smooth ER - no ribosomes attached • Rough ER - ribosomes are attached

  16. Endoplasmic Reticulum Function (job): • Transports materials “intracellular

  17. Golgi Bodies Structure: • Series of flattened sacs

  18. Golgi Bodies Function (job): • Processes, packages and secretes material • Materials that are transported by the ER usually stop first at the Golgi bodies where they are stored or altered before moving to other parts of the cell

  19. Lysosomes Structure: • Round organelles surrounded by a membrane. Function (job): • Contains powerful digestive enzymes

  20. Vacuoles Structure: • Fluid-filled sacs that float in the cytoplasm

  21. Vacuoles Function (job): • Stores water and food materials • Stores waste and helps the cell get rid of waste

  22. Cell types: • Prokaryotic cell - very simple; no membrane-bound structures (ex: bacteria) • Eukaryotic cell - more advanced; has membrane-bound structures (ex: animal cells, plant cells)

  23. Organization of Living Things Five main levels of organization 1. Cell 2. Tissue 3. Organ 4. Organ System 5. Organism

  24. Tissue • Example: Muscle • Tissues are made of specialized cells.

  25. Organ • Examples: Heart, Lung, Brain • Found in both plants and animals. • Composed of tissue that is organized into groups that work together to perform special functions.

  26. Organ System • Example: Circulatory System • A group of organs that work together.

  27. 1. Circulatory 2. Digestive 3. Nervous 4. Respiratory 5. Skin 6. Skeletal 7. Muscular 8. Reproductive 9. Excretory 10.Endocrine 10 Organ Systems in complex organisms(humans, dogs, birds, etc.)

  28. Different organ systems work together to keep the organism alive. ORGANISMS

  29. Classify the following as a tissue, organ, or organ system.a. Brain, spinal cord, and nerves b. Heartc. Group of muscle cells QUESTION:

  30. Can a single-celled organism contain tissue? Explain. QUESTION:

  31. Give one example of each:a. Cell c. Tissueb. Organ d. Organism QUESTION:
