Characteristics of living things Presentation Transcript

  • 1. Characteristics of Living Things
  • 2. Characteristics of Living Things1. Living things respond to Stimulisuch as light, sound, temperatureand pressure.
  • 3. 2. All living things perform different lifeprocesses such as: a. METABOLISM the used or released of energy in order to perform different life processes. Metabolism includes the: a)breaking down food
  • 4. Metabolism includes the: b) building body parts c) removing waste
  • 5. Metabolism includes the: b) building body parts c) removing waste d) releasing energy e) movement
  • 6. b. ADAPTATIONThe ability of living toadapt to any changes intheir environment.
  • 7. c. GROWTHAll living things take in food or produce theirown food. Plants make their own foodAnimals take using water and carbonfood by simple dioxide along with energyputting food into from the suntheir mouth.
  • 8. Living things use the energy they get from thefood to grow.Growth does not only involved increase in size.Growth for most living things involvesdevelopment.
  • 9. d. REPRODUCTIONLiving things produce their own kind.
  • 10. Cells as Unit of StructureOur body is made up of trillions of buildingblocks of life called CELLS.Cells were discovered by anEnglish scientist, Robert Hooke,over 300 years ago.He was looking at a thin slice ofcork under a microscope.He saw that the cork showedregular patterns of tiny, openspaces.The pattern reminded him of tiny rooms that he called“cells”
  • 11. All the activities of life take place in each cell. Every cell in our body is a living building block. Each cell takes in food and gets rid of wastesOur body is made up of many kinds of cells that dodifferent jobs.
  • 12. The cells in our body form tissue.Tissue is a group of the same kind of cells. Nerve cell Nerve tissueEach kind of tissue does a certain job.Nerve cells form nerve tissues that carry messagesbetween our brain and other parts of the body.
  • 13. Different tissues that work together form anORGAN.
  • 14. Different organs that work together make up anORGAN SYSTEM. Digestive organ
  • 15. Cell Structure and Function
  • 16. Cell Membrane Is a thin, flexible membrane surrounding the cell.In an animal cell, the cell membrane forms the outercovering of the cell.In a plant cell, the cell membrane is inside the cell wall.
  • 17. Cell WallThe cell wall of plant cells contains cellulose, a nonlivingmaterials.Cellulose is a long chain of sugar molecules that is madeby the cell.
  • 18. Food, water, and oxygenpass into the cell throughthe cell membrane.Wastes pass out of thecell through the cellmembrane too. In plants, although the cell wall is thick, it does allow water and gases to pass through. The plant cell wall helps give protection and support so the plant can grow tall.
  • 19. The nucleus is the control center of the cell.It controls all cellular activities.
  • 20. The thin membrane that separates the nucleus from the rest of the cell is called Nuclear Membrane.Nuclear Membrane is similar to cell membrane.Nuclear membrane allows materials to pass into and out ofthe nucleus.
  • 21. Outside the nucleus is a clear, thick jellylike materialscalled Cytoplasm, which is constantly moving.Cytoplasm is the term for all the protoplasm, or livingmaterials of the cell, outside the nucleus.
  • 22. Cytoplasm is where the food, water, and oxygen taken in by the cell are used.The cytoplasm contains other structure like the:a) ribosomesb) endoplasmic reticulumc) Mitochondriad) lysosomes
  • 23. It is the site of proteinsynthesis
  • 24. EndoplasmicReticulum is involved in the transport of proteins.
  • 25. Mitochondria supply most of the energy of the cell and are often referred to as the „powerhouse”
  • 26. Lysosomes are small, round structures involvedin the digestive activities of the cell.
  • 27. Vacuoles act like storage tanks. Food and other materials needed by the cell are stored inside the vacuolesPlant cells have large vacuoles while animalcells have few, small vacuoles.
  • 28. CentriolesVery important during the cell division
  • 29. The primary Golgi body functions are to modify the new proteins synthesized from the ER present in the cytoplasm, then process them and sort them for transportation.The Golgi body is a veryimportant cell organelle in oursystem and without it, no livingcell can function appropriately.
