Presentation Transcript

  1. Prokaryote • The prokaryotes are a group of organisms whose cells lack a cell nucleus.

  2. Eukaryote • A eukaryote is an organism whose cells contain complex structures enclosed within membranes.

  3. Organelle • Tiny structures that carry out functions necessary for the cell to stay alive

  4. Nucleus • Control center of the cell

  5. Ribosome • small organelles that make proteins

  6. Cytoplasm • region between the cell membrane and the nucleus

  7. Vacuole • an organelle that stores food, water, and other materials needed by the cell

  8. Lysosome • contain substances that break down large food particles into smaller ones

  9. Chloroplast • A structure in the cells of plants and some other organisms that captures energy from sunlight and uses it to produce food.

  10. Mitochondria • organelles that convert the chemical energy stored in food into compounds that are more convenient for the cell to use

  11. Cilia and Flagella

  12. Chlorophyll • Chlorophyll is a green pigment found in cyanobacteria and the chloroplasts of algae and plants.

  13. Cell Wall • A rigid structure that surrounds the cells of plants and most bacteria

  14. Plasma Membrane • thin, flexible barrier around a cell; regulates what enters and leaves the cell

  15. Microfilaments/Microtubules • Microfilaments or actin filaments are the thinnest filaments of the cytoskeleton, a structure found in the cytoplasm of eukaryotic cells. • Microtubules are a component of the cytoskeleton, found throughout the cytoplasm. These tubular polymers of tubulin can grow as long as 25 micrometres

  16. Golgi Apparatus • receives proteins and other newly formed materials from the ER, packages them, and distributes them to other parts of the cell or to the outside of the cell

  17. Endoplasmic Reticulum • network of membranes within a cell's cytoplasm that produces a variety of substances

  18. Chromatin • contains information for directing a cell's activities

  19. Centrioles • A centriole is a cylinder shaped cell structure found in most eukaryotic cells, though it is absent in higher plants and most fungi.
