U2 LESSON 2 Plant cell parts and functions

• Robert Brown (1833) - discovered the nucleus in plant cells
• Felix Dujardin (1835) - said that cells contain gelatinous fluid, a life substance called “sarcode”
• Johannes Purkinje (1839) - first to use the word “protoplasm” in the modern sense

       Protos - first

       Plasm - thing form
• Rudolph Albert von Kolliker (1874) - coined the term “cytoplasm” from protoplasm
• • Protoplasm INCLUDES nucleus and cytoplasm
  • Cytoplasm INCLUDES the organelles, except the nucleus
• plant cell

  
• animal cell

  
• Microtubules are made of tubulin and microfilaments are made of actin.
