The document discusses the basic structure and organization of cells. It begins by outlining the main characteristics of living things and then describes the different levels of organization, from atoms and molecules up to biomes and the biosphere. It then provides details on the basic structure of plant and animal cells, including the organelles and their functions. It discusses the differences between prokaryotic and eukaryotic cells and describes specialized cell types.

43. Specialized Plant cells Xylem cells Pollen Guard Cells

44. Organization Levels of Life Atoms to Organisms

45. ATOMS  MOLECULES  ORGANELLES Nonliving Levels

46. CELLS – life starts here TISSUES – Similar cells working together Living Levels  

47. ORGANS ORGAN SYSTEMS ORGANISM Different tissues working together Different organs working together   More Living Levels

48. Simple or Complex Cells

53. Two Main Types of Eukaryotic Cells Plant Cell Animal Cell

54. Organelles

56. Animal Cell Organelles Nucleolus Nucleus Nuclear envelope Ribosome (attached) Ribosome (free) Cell Membrane Rough endoplasmic reticulum Golgi apparatus Mitochondrion Smooth endoplasmic reticulum Centrioles

57. Plant Cell Organelles

71. Inside the Nucleus - The genetic material (DNA) is found DNA is spread out And appears as CHROMATIN in non-dividing cells DNA is condensed & wrapped around proteins forming as CHROMOSOMES in dividing cells

75. Cytoskeleton MICROTUBULES MICROFILAMENTS

82. What do mitochondria do? Burns glucose to release energy (ATP) Stores energy as ATP “ Power plant” of the cell

88. Endomembrane System Includes nuclear membrane connected to ER connected to cell membrane (transport)

93. Golgi

94. Golgi Animation Materials are transported from Rough ER to Golgi to the cell membrane by VESICLES

99. Cell Movement with Cilia & Flagella

100. Cilia Moving Away Dust Particles from the Lungs Respiratory System
