The word cell was first used in 1665 by the Englishman Robert Hooke (1635-1703). With a very simple microscope he observed pieces of cork, and realized that it was formed by empty compartments that he called cells.
Animal cell It is a cell that can be found in animals and is distinguished from the plant cell by the absence of cell wall and plastos. It has flagella, which is not common in plant cells.
- Animal Cell (no chloroplasts and no cell wall; several small vacuoles)
Metabolism - Organs
- Nucleolus: stores genetic charge
- Cell nucleus: DNA chromosomes
- Ribosomes: make protein synthesis
- Ergastoplasma or Rough Endoplasmic Reticulum (RER): protein transport (ribosomes are attached to it)
- Golgi Complex: Stores and Releases Proteins
- Smooth Endoplasmic Reticulum: Lipid Production
- Mitochondria: Breathing
- Vacuole: They exist in the animal cell, but are much larger in the plant cell, serving as an energy reserve.
- Lysosomes: Digestion
- Centrioles: Cell Division
