Presentation Transcript

  1. The Cell How do cell parts interact to help the cell function as a system to meet the characteristics of life?

  2. Systems • A system is something with two or more parts that interact • A change to one part of the system will cause a change to the overall system • The cell is a system

  3. The Cell • The cell is the smallest unit of life • It is made of small parts called organelles (little organs) which work together so the cell will function correctly • Plant, animal, and bacteria cells are structured differently

  4. Cell Membrane • All cells have a cell membrane that controls what enters/leaves the cell and helps protect it from the outside environment

  5. Cell Wall • The cell wall surrounds plant cells, as well as some fungal and bacterial cells • It surrounds the cell membrane and serves as extra protection • In some plant and fungal cells, it also provides structure/support

  6. Plant Cell • Bacteria cell

  7. Nucleus • The “brain” of the cell • Gives the other organelles instructions so that they can carry out their functions • Contains DNA (deoxyribonucleic acid), genetic material that determines how an organism looks and contains the “instructions for life”

  8. Mitochondrion(plural = mitochondria) • Produces energy for the cellthrough the process of cellular respiration so the cell can carry out its functions • Cellular respiration is a chemical reaction where food is converted into energy

  9. Chloroplast • Found in plant cells and some single celled organisms • Contain a green pigment called chlorophyll • Carries out photosynthesis, a chemical reaction where the cell uses sunlight to convert carbon dioxide and water into food called glucose (sugar)

  10. Other Organelles • Ribosome- manufacture proteins (each protein has a unique function) • EndoplasmicReticulum - makes ribosomes and lipids (used in membranes and energy storage) and helps transport those materials around the cell • GolgiApparatus – packages substances in the cell • Lysosome- break down and recycle cell components • Vacuole – store food, water, and waste; plant cells contain a giant one that stores water to give the cell support
