5. 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
6. 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
7. Vital functions REPRODUCTION New individual living beings are produced. Asexual reproduction: one parent Sexual reproduction: male and female parents Living beings GO BACK
8. water mineral salts Biomolecules calcium, iron, magnesium, etc. Organic molecules
9. 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
10. 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.
