  1. Cell
    The smallest functional and structural unit of all living things
  2. Organism
    Is any living thing. All organisms are made up of cells
  3. Cell membrane
    a protective layer that covers a cell's surface and acts as a barrier between the inside of a cell and the cell's environment
  4. Cytoplasm
    The region of the cell within the membrane that includes the fluid, the cytoskeleton, and all of the organisms except for the nucleus
  5. Organelle
    Is a small body in a cell's cytoplasm that is specialized to perform a specific function
  6. Nucleus
    • Where the thinking is usually done.
    • in the eukaryotic cell the nucleus has a role either as growth, metabolism, and reproduction
  7. Prokaryotic
    Is a single-celled organism that does not have a nucleus or membrane-bound organelles
  8. Eukaryotic
    Is an organism made up of cells that contain their DNA in the nucleus added note most are multicellular but some are unicellular.  the eukaryotic cells are not all the same 
  9. Atom
    Both non living and living, is made up of these basic particles
  10. Molecule
    Is a group of atoms that are held together by chemical bonds
  11. Lipid
    Is a fat material or a molecule that has similar properties
  12. Protein
    Is a molecule made up of smaller molecules called amino acids
  13. Carbohydrate
    Molecules that includes sugar starches and fiber and they use them as a source of energy and energy storage
  14. Nucleic acid
    The molecule that carries information in the cells
  15. Phospholipid
    Lipid that contains phosphoris
  16. Cytoskeleton
    It's a network of protein  flatmates that give shape and support to cells
  17. Mitochondrion
    This is my cellular respiration occurs and cellular respiration uses oxygen to release energy in stored food
  18. ribosome
    And is this organelle that makes proteins by putting together chains of a aminio acids using instructions encoded in the cells DNA
  19. Endoplasmic reticulum a.k.a. ER
    It assists in the production of processing in transport of protein and in the production of lipids
  20. GOLGI complex
    A cell organells that helps make and package materials to be transported out of the cell
  21. Cell wall
    The wall is a rigid structure that surrounds the cell membrane
  22. vacuole
    Is a fluid filled vessel found in the cells most of animals  plants and fungi
  23. chlorplast
    This is in  a plant cell and it is where photosynthesis occurs  photosynthesis is the process by which cells use sunlight carbon dioxide and water to make sugar and oxygen
  24. lysosomes
    These contain digestive enzymes that break down worn-out or damages organelles, waste materials and foreign invaders inside the cell
  25. Homeostasis
    This is the maintenance of a constant internal state in a changing environment
  26. Xylem
    This is the tissue that Transports water and minerals from the roots to the rest of the plant
  27. Phloem
    transports food made with in plant cells
  28. Photosynthesis
    This process by which plants algae and some bacteria make their own food
  29. Cellular respiration
    The process by which cells use oxygen to produce energy from food, plants,animals,and most other organisms use this
  30. Cell cycle
    During a self lifecycle or cell cycle a cell can undergo cell division in order to make new cells
  31. Mitosis
    Cell division that form nuclei are identical to each other is called and it ensures that each new cell received a copy of each chromosome
  32. Passive transport
    The movement of particles across a cell membrane without the use of energy by the cell
  33. Diffusion
    Is the movement of molecules from high concentrates to low concentrations
  34. Osmosis
    Is the diffusion if wate through a semi- permeable membrane
  35. Active transport
    Is the movement of particles against a concentration gradient and requires the cell to use energy
  36. Endocytosis
    The process by which a cell uses energy to surround a particle and enclose the particle in a vesicle to bring the particle in to the cell
  37. Exocytosis
    When particles are enclosed in a vesicle and released from the cell
  38. Organism
    Is a living thing that can carry out life processes by itself
  39. Tissue
    Is a group of similar cells that perform a common function
  40. Organ
    Structure  made up of a collection of tissues that carries out a specialized function


    cells – tissues – organs – organ system
  41. Organ system
    Is a group of organs that work together to perform body functions
  42. Structure
    Is the arrangement of  parts in the organism or an object
  43. Function
    The activity of each part in an organism
  44. cell theory
    The cell theory is fundamental to the study of organisms medicine hereditary evolution and all other aspects of life science
  45. Multicellular organisms
    Contain more than one cell inside of the organism
  46. Unicellular organism
    Contains only one cell in the  organism
  47. Elements
    Each different type of atoms are known as these
  48. Compound
    A substance that is made up of atoms of one or two more elements joined by chemical bonds is called this
  49. Enzymes
