• Cell is the basic membrane-bound unit that contains the fundamental molecules of life and of which all living things are composed
• Cell is the smallest living organism and the basic unit of life on earth
• Cell biology is a branch of biology that focuses on the study of cells, their structure, function, and life processes
• Cell biology involves the examination and analysis of cells, including their organelles and other cellular components, to understand the fundamental principles governing life at the cellular level
• Microscope is an optical instrument used to magnify and observe objects that are too small to be seen with the naked eye
• Microscope enables scientists, researchers, and students to study the details of tiny structures such as cells, microorganisms, and small particles by making them appear larger and more visible
• Cell theory states that cells are the basic units of all living tissues
• Cell theory was proposed by Matthias Schleiden for plant tissues and extended to animals by Theodor Schwann
• Rudolf Virchow contributed the principle "Omnis cellula e cellula" (All cells come from pre-existing cells) to the cell theory
• Basic principles of the cell theory:

  • All living organisms are composed of cells
  • Cells are the basic unit of life
  • Cells come from pre-existing cells
• Modern cell theory:

  • All living organisms are composed of cells
  • Cells are the basic unit of life
  • Cells come from pre-existing cells
  • The genetic material is contained in cells
  • Energy flow occurs within cells
  • Cells of all organisms within a similar species are mostly the same both structurally and chemically
• plant tissues were composed of

  individual cells and aggregates of cells
• The nucleus is the control center of the cell, containing DNA.
• Virchow's contribution to the cell theory was the idea that new cells arise only from preexisting cells.
• Schwann's work on animal tissue led him to propose that all living things consist of cells.
• Konseptong Papel


  Tinatawag din itong Panukalang Papel
• Konseptong Papel


  • Isa sa mga pangunahing kailangan bago ang aktwal na pagsulat ng isang Papel-Pananaliksik
  • Nagsisilbing proposal para maihanda ang isang pananaliksik
  • Unang hakbang sa pagsasagawa ng pagsisiyasat
  • Maikling akademikong papel na nagbibigay ng pangkalahatang impormasyon tungkol sa isang panukalang saliksik
  • Naging gabay sa mga hakbanging naisisagawa mula sa simula hanggang sa katapusan ng pagsisiyasat
  • Nagsisilbing outline o istruktura ng kabuuang pag-aaral
  • Tinitiyak ng konseptong Papel ang pagkakaroon ng isang komprehensibong plano at awtput ng pananaliksik ukol sa isang paksa, isang kabuuuang ideya na nabuo mula sa isang balangkas ng paksang bubuuin
