Vital functions VITAL FUNCTIONS Living beings NUTRITION INTERACTION REPRODUCTION
Vital functions NUTRITION  Living beings obtain  the  matter  and  energy   necessary for life. Autotrophic organisms inorganic matter organic matter Heterotrophic organisms Living beings GO BACK
Living beings Vital functions INTERACTION Living beings relate  with their surrounding  environment. Animals have  receptors and  effectors . Plants do not have  receptors, but they  can respond to stimuli.  GO BACK
Vital functions REPRODUCTION New individual living  beings are produced. Asexual reproduction: one parent Sexual reproduction: male and female parents  Living beings GO BACK
water mineral salts  Biomolecules calcium, iron, magnesium, etc. Organic molecules
History of cell discovery He was the first person to use the word “cell”.  He discovered tiny organisms in a drop of water. 1675 Anthony van Leeuwenhoek microscope “ animacules” 1665 Robert Hooke microscope cork under a microscope
History of cell discovery 1838 Matthias J. Schleiden and Theodor  Schwann CELL  THEORY The cell is the structural and functional unit of all living things. 1855 Rudolf Virchow CELL THEORY All cells come from  pre-existing cells.
