1 Cells 2 Cell Theory { { 3 Cells are the basic unit of structure and function of all living things Cells come from pre-existing cells Contributing Scientists { Anton Van Leeunhoek { Robert Hooke z z Robert Brown { Mathias Schleiden z { Louis Pasteur { Organelles { Plasma Membrane or Cell Membrane { Cytoplasm z z z z Fluid like environment between nucleus and the plasma membrane The goo inside Gives the cell shape Gives a place for the organelles to sit in so they don’t move around as much { Nucleus { Nucleolus z Contains genetic information in chromosomes and directs all cell activities. Inside the nucleus, synthesis of ribosome's Organelles { Endoplasmic Reticulum z z Interconnecting channels associated with storage. Associated with synthesis and transport of substances in the cell. Organelles { Ribosome's z Site of protein synthesis Organelles { Mitochondria z z Produces ATP The power house of the cell Organelles { Golgi Complex z 11 Holds in cytoplasm. Controls what goes in and out of the cell Organelles z 10 Cells come from pre-existing cells Cells are made up of smaller parts called organelles. z 9 Proved tiny organisms (microbes) caused disease Cell Organelles { 8 All animals are made up of cells Rudolph Vicchow z 7 Determined plants were made of cells Theodor Schwann z 6 Discovered the nucleus { z 5 Used a 2 lens microscope to examine the bark of a tree. Discovered empty cork cells that led to the discovery of cell walls, and he named them cells { z 4 Discovered one-celled organisms in the water by using a simple one lens microscope Sacs that make cellular products Organelles { Lysosomes z Contain digestive enzymes 1 12 Organelles { Vacuole z 13 Organelles { Centrioles: z z 14 Chloroplasts z z Site for photosynthesis Contain Chlorophyll Plant Vs Animal Cell { Plant cell z z z z 16 Only found in animal cells Function during cell division Organelles { 15 Storage. Can be specialized for waste management or it could be a contractile vacuole and control water balance. Has a cell wall made of cellulose Contains chloroplasts and chlorophyll Gave the name to cells because they appear like a structured bunch of cells together. Cell divides from inside out Plant vs. Animal Cell { Animal Cells z z z Only has a cell membrane Has centrioles used to help cell division Cell divides from outside in 2
