1 GENERAL BIOLOGY REVIEWER

• Gates and walls of the house

  Plasma Membrane
• Powerhouse or the energy source of the cell

  Mitochondria
• Gelatin-like surface

  Cytoplasm
• Control-center or brain of the cell

  Nucleus
• Macro-Machine for making Proteins

  Ribosomes
• A sphere-like structure inside the nucleus that produce and assemble cell's ribosome

  Nucleolus
• Small vacuoles. They break down fatty and amino acids

  Peroxisomes
• Digestive system of the cell. It breaks down and digest food particles in a cell

  Lysosomes
• Roadway to produce proteins

  Endoplasmic Reticulum
• Fuel pump of the cell that pushes/sends the package

  Golgi Apparatus
• Whip-like structure

  Flagella
• Small and hair-like structure

  Cillia
• Solar panel of the cell because its energy comes from the sun

  Chloroplast
• One of the major branch of Biology that studies the function and structures of plant and animal cells with the help of microscope

  Cytology
• He was the first person to demonstrate cells using cork cells (bark tree) in his book called Micrographia (1665) he saw a dead plant cell. They're small squares that look like a monastery of the monks which are called cells.

  Robert Hooke
• He was the first person to observe the blood and sperm cell. He is also known as the "Father of Microbiology"

  Anton Van Leeuwenhoek
• Leeuwenhoek introduced the first unicellular or one one-celledcelled organism called ______ . He called it as animalcules or the wretched beasties

  Protozoa
• He greatly contributed to improving microscope which is one of the primary needed to study biology

  Anton Van Leeuwenhoek
• This scientist discovered the plant cell out of its vegetative/meristematic tissues and the embryonic plants organized

  Matthias Schleiden
• 1676

  Anton Van Leeuwenhoek
• 1838

  Matthias Schleiden
• 1839

  Theodor Schwann
• 1858

  Rudolf Virchow
• He generalized that all plants are made of cells

  Matthias Schleiden
• He is the person to discovered animal cells using muscle and nerve fiber tissues now called Schwann cells. His discovery also led him to conclude that all animals are made of cells. After studying the theory of Schleiden, He proposed that all organisms are made out of cells.

  Theodor Schwann
• He is the proponent of the cell theory's third postulate which states that, "all cells came from pre-existing cells"

  Rudolf Virchow
• 2 barrel-shaped clusters that served as the main microtubule-organizing centers for cells (MTOC)

  centrosome
• The beams of the house. It helps the cell maintain its shape and internal organ

  Cytoskeleton
• 1. All living organisms are composed of one or more cells.
  2. The cells are the basic unit of life in all living things
  3. All cells came from pre-existing cells

  The Three Postulates of Cell Theory
• contains only one single cell

  unicellular
• performs all life functions of the cell

  unicellular
• It can only be seen using microscope (Microscopic)

  unicellular
• Reproduce through budding and binary fission

  unicellular
• This organism has both prokaryotic and eukaryotic cells

  unicellular
• contains multiple cells

  multicellular
• performs different life functions

  multicellular
• visible to naked eye

  macroscopic
• reproduce through gamete fusion

  multicellular
• include organisms with only eukaryotic cell types

  multicellular
• these are little organs that are separated membranous compartments inside the cells

  cell organelles
